Custom Animated Range Slider using HTML CSS & JavaScript
In this video you’ll learn how to create a Custom Animated Range Slider Using HTML CSS & JavaScript. Earlier I have shared a blog on how to create a Page Screen Preloader using JavaScript. And now I’m going to create a Custom Range Slider.
The range slider offers two handles to set a min and max value with a numeric continuum. Range Sliders are used on web pages to let the user define a numeric value which must be no less than a given value, and no more than another given value. That is, it permits us to choose a value from a range that is represented as a slider.
In this program (Custom Animated Range Slider), on the webpage, there is a white container box and inside this box, there is a range slider. At first, that center tooltip value is hidden but when you slide or change the value of range slider then the center tooltip value is visible and this value is dynamic but the other two values are fixed.
Dynamic value means that value change according to the range value but the left and right side values are fixed and it doesn’t change. You can also create a default range slider using HTML5 <input type="range"> but default range slider can’t attract the visitors and content viewers towards the website. If you’re feeling difficult to understand what I am saying. You can watch a full video tutorial on this program (Custom Animated Range Slider).

How to Automatic Image Slider in Html, CSS and Javascript
In this article, you will learn how to create an automatic image slider using HTML CSS, and JavaScript code. Earlier I shared with you many more types of manual and automatic image sliders. Like other designs, I hope you like this design.
Image slider is a common web element that is currently used in many websites. It is mainly used for the slideshow on the website’s homepage. This type of Auto Image Slideshow is also used to organize many images in a gallery. If you want to learn more about javascript, check out my best HTML, CSS, and javascript projects.
There are two types of image sliders, one automatic and the other manual. In the case of the automatic image slider, the image will change automatically at regular intervals. In the case of the manual, you need to change the image using the Next and Previous buttons.
Automatic Image Slider
In this case, the image can be changed automatically and manually. This means that it will automatically change the image and you can also change the image using the Next and Previs buttons separately.
The design can only be created with the help of HTML and CSS but in this case, I have used JavaScript programming code.
If you want to know how these automatic image slideshows work then you can watch the live demo below. Below I have given the source code so you can copy them if you want. You can also download the code using the download button at the bottom of the article.
As you can see in the demo above, this is a very simple image slider with automatic and manual image changes.
In this case, I have used a total of five images but you can use many more if you want. The image will change automatically every 5 seconds. There are also two buttons to change the image.
Automatic Image Slider in Html, CSS, and Javascript
If you know basic HTML CSS and JavaScript then you can easily understand this design. To create this automatic image slider, first, you need to create an HTML and CSS file.
In this case, I did not create a separate JavaScript file, but you can create a separate file if you want.
Step 1: Create the basic structure of the slider
I have used a little HTML and CSS code below to create the background of this slider. In this case, I have used the slider height 256 px and width 500 px.
I didn’t use any different colors in the background. If you have seen the demo, you will understand that a shadow has been used around this slide for which I have used box-shadow: 0 0 30px rgba(0, 0, 0, 0.3) here.
<div id=”slider”>
</div>
body {
margin: 10%;
}
#slider {
position: relative;
width: 500px;
height: 265px;
overflow: hidden;
box-shadow: 0 0 30px rgba(0, 0, 0, 0.3);
}
Step 2: Add the required images
I have added images to this Automatic Image Slider using the code below and designed those images. I have used a total of five images you can increase or decrease as you wish.
If you take a closer look at the CSS code below, you will understand that I have used Slider Ul Width 10000%.
You may wonder why I used 10,000% here. Take a good look at the image below to understand why and how this slider works.
<ul id=”slideWrap”>
<li><img src=”img1.jpg” alt=””></li>
<li><img src=”img2.jpg” alt=””></li>
<li><img src=”img3.jpg” alt=””></li>
<li><img src=”img4.jpg” alt=””></li>
<li><img src=”img5.jpg” alt=””></li>
</ul>In this case, the height of the image is 256 px and the width is 500 px. Of course in this case you will use the same size of each image.
#slider ul {
position: relative;
list-style: none;
height: 100%;
width: 10000%;
padding: 0;
margin: 0;
transition: all 750ms ease;
left: 0;
}
#slider ul li {
position: relative;
height: 100%;
float: left;
}
#slider ul li img{
width: 500px;
height: 265px;
}
Step 3: Add prev and next button
Now we will add the Previs and Next buttons to this slider. The HTML and CSS code below helped to add and design these two buttons.
<a id=”prev” href=”#”>≪</a>
<a id=”next” href=”#”>≫</a>
#slider #prev, #slider #next {
width: 50px;
line-height: 50px;
border-radius: 50%;
font-size: 2rem;
text-shadow: 0 0 20px rgba(0, 0, 0, 0.6);
text-align: center;
color: white;
text-decoration: none;
position: absolute;
top: 50%;
transform: translateY(-50%);
transition: all 150ms ease;
}Step 4: Determine the exact location of the two buttons
I have used a little CSS below to place these two buttons in their proper place. I kept the Previs button 10 pixels away from the left.
I kept the next button 10 px away from the right. As a result, these two buttons are located on either side of the slider.
#slider #prev {
left: 10px;
}
#slider #next {
right: 10px;
}I have used the following CSS code to use a small amount of hover effect in the background of these two buttons.
#slider #prev:hover, #slider #next:hover {
background-color: rgba(0, 0, 0, 0.5);
text-shadow: 0;
}
Step 5: Activate the image slider by adding JavaScript code
So far we have only designed it, now we will implement the image change of this slider.
var responsiveSlider = function() {
var slider = document.getElementById(“slider”);
var sliderWidth = slider.offsetWidth;
var slideList = document.getElementById(“slideWrap”);
var count = 1;
var items = slideList.querySelectorAll(“li”).length;
var prev = document.getElementById(“prev”);
var next = document.getElementById(“next”);
window.addEventListener(‘resize’, function() {
sliderWidth = slider.offsetWidth;
});First of all, we will decide in advance what kind of work will be done by clicking on the Next button. If you are a beginner then first of all look at the code structure below. Then follow the explanation below which will help you understand better.
var nextSlide = function() {
if(count < items) {
slideList.style.left = “-” + count * sliderWidth + “px”;
count++;
}
else if(count = items) {
slideList.style.left = “0px”;
count = 1;
}
};
As we have seen, in the nextSlide variable, we have stored how the Next button will work.
First, we added value if (count <items) this code will work when the amount of image is more than count.
Using else if (count = items) we have determined what will happen if the previous function does not work. If both the image and the count are equal then there will be no change in the slider.
‘count’ is the number of times you clicked on the button. If you click on that button once, the value of the count is one. If you click three times at once, the value of the account is 3.
We have decided what kind of change will happen if we click on the Next button. Now we will implement the previous button.
Similarly here we have determined what kind of effect will work if you click on the previous button.
var prevSlide = function() {
if(count > 1) {
count = count – 2;
slideList.style.left = “-” + count * sliderWidth + “px”;
count++;
}
else if(count = 1) {
count = items – 1;
slideList.style.left = “-” + count * sliderWidth + “px”;
count++;
}
};
Determining what kind of effect will work when clicking the previous and Next buttons in this Automatic Image Slider. Now we will associate those effects with two buttons.
As I said earlier, we have stored how the Next button will work in a constant called ‘next Slider’. Now below we have instructed that if you click on the Next button, that constant will work.
next.addEventListener(“click”, function() {
nextSlide();
});We’ve saved what works on the previous button in the ‘prevSlide’. Now below we have instructed that if you click on the previous button, that constant will work.
prev.addEventListener(“click”, function() {
prevSlide();
});Since this is an automatic image slider, in this case, I have arranged for the image to change automatically. Here I have used 5000 i.e. 5 seconds. This means the image will change every 5 seconds. If you want the images to change every 2 seconds, use 2000 instead of 5000 here.
setInterval(function() {
nextSlide()
}, 8000);
};
window.onload = function() {
responsiveSlider();
}
Hope you learned from this tutorial how I created this beautiful automatic image slider using HTML CSS and JavaScript code. If you want to download the required source code, you can use the download button below.
If you have any problem understanding how to make this auto image slider then you can definitely let me know by commenting.

如何在 Html、CSS 和 Javascript 中使用自动图像滑块
在本文中，您将学习如何使用 HTML CSS 和 JavaScript 代码创建自动图像滑块。早些时候，我与您分享了更多类型的手动和自动图像滑块。和其他设计一样，我希望你喜欢这个设计。
图像滑块是一种常见的网络元素，目前在许多网站中使用。主要用于网站首页的幻灯片放映。这种类型的自动图像幻灯片还用于组织图库中的许多图像。如果您想了解有关 javascript 的更多信息，请查看我最好的HTML、CSS 和 javascript 项目。
有两种类型的图像滑块，一种是自动的，另一种是手动的。在自动图像滑块的情况下，图像将定期自动更改。对于手册，您需要使用“下一个”和“上一个”按钮更改图像。
自动图像滑块
在这种情况下，可以自动和手动更改图像。这意味着它会自动更改图像，您也可以 分别使用 Next 和 Previs 按钮更改图像 。
该设计只能在 HTML 和 CSS 的帮助下创建，但在这种情况下，我使用了 JavaScript 编程代码。
如果你想知道这些自动图像幻灯片是如何工作的，那么你可以观看下面的现场演示。下面我给出了源代码，所以你可以根据需要复制它们。您还可以使用文章底部的下载按钮下载代码。
正如您在上面的演示中看到的，这是一个非常简单的图像滑块，具有自动和手动图像更改功能。
在本例中，我总共使用了五张图片，但如果你愿意，你可以使用更多图片。图像将每 5 秒自动更改一次。还有两个按钮可以更改图像。
Html、CSS 和 Javascript 中的自动图像滑块
如果您了解基本的 HTML CSS 和 JavaScript，那么您可以轻松理解此设计。要创建这个自动图像滑块，首先，您需要创建一个 HTML 和 CSS 文件。
在本例中，我没有创建单独的 JavaScript 文件，但如果需要，您可以创建一个单独的文件。
第 1 步：创建滑块的基本结构
我在下面使用了一些 HTML 和 CSS 代码来创建这个滑块的背景。在本例中，我使用的滑块高度为 256 像素，宽度为 500 像素。
我没有在背景中使用任何不同的颜色。如果你看过演示，你就会明白这张幻灯片周围使用了阴影，我在这里使用了 box-shadow: 0 0 30px rgba(0, 0, 0, 0.3)。
<div id=”slider”>
</div>
body {
margin: 10%;
}
#slider {
position: relative;
width: 500px;
height: 265px;
overflow: hidden;
box-shadow: 0 0 30px rgba(0, 0, 0, 0.3);
}第 2 步：添加所需的图像
我使用下面的代码向这个自动图像滑块添加了图像并设计了这些图像。我一共使用了五张图片，你可以随意增减。
如果你仔细看看下面的 CSS 代码，你就会明白我使用了 Slider Ul Width 10000%。
你可能想知道为什么我在这里使用 10,000%。仔细查看下图，了解此滑块工作的原因和方式。
<ul id=”slideWrap”>
<li><img src=”img1.jpg” alt=””></li>
<li><img src=”img2.jpg” alt=””></li>
<li><img src=”img3.jpg” alt=””></li>
<li><img src=”img4.jpg” alt=””></li>
<li><img src=”img5.jpg” alt=””></li>
</ul>在本例中，图像的高度为 256 像素，宽度为 500 像素。当然，在这种情况下，您将使用相同大小的每个图像。
#slider ul {
position: relative;
list-style: none;
height: 100%;
width: 10000%;
padding: 0;
margin: 0;
transition: all 750ms ease;
left: 0;
}
#slider ul li {
position: relative;
height: 100%;
float: left;
}
#slider ul li img{
width: 500px;
height: 265px;
}第三步：添加上一个和下一个按钮
现在我们将 Previs 和 Next 按钮添加到此滑块。下面的 HTML 和 CSS 代码有助于添加和设计这两个按钮。
<a id=”prev” href=”#”>≪</a>
<a id=”next” href=”#”>≫</a>
#slider #prev, #slider #next {
width: 50px;
line-height: 50px;
border-radius: 50%;
font-size: 2rem;
text-shadow: 0 0 20px rgba(0, 0, 0, 0.6);
text-align: center;
color: white;
text-decoration: none;
position: absolute;
top: 50%;
transform: translateY(-50%);
transition: all 150ms ease;
}第四步：确定两个按钮的准确位置
我在下面使用了一些 CSS 将这两个按钮放在适当的位置。我将 Previs 按钮保持在距左侧 10 像素的位置。
我将下一个按钮保持在距离右侧 10 px 的位置。因此，这两个按钮位于滑块的两侧。
#slider #prev {
left: 10px;
}
#slider #next {
right: 10px;
}我使用下面的 CSS 代码在这两个按钮的背景中使用了少量悬停效果。
#slider #prev:hover, #slider #next:hover {
background-color: rgba(0, 0, 0, 0.5);
text-shadow: 0;
}第 5 步：通过添加 JavaScript 代码激活图像滑块
到目前为止我们只是设计了它，现在我们来实现这个滑块的图像变化。
var responsiveSlider = function() {
var slider = document.getElementById(“slider”);
var sliderWidth = slider.offsetWidth;
var slideList = document.getElementById(“slideWrap”);
var count = 1;
var items = slideList.querySelectorAll(“li”).length;
var prev = document.getElementById(“prev”);
var next = document.getElementById(“next”);
window.addEventListener(‘resize’, function() {
sliderWidth = slider.offsetWidth;
});首先，我们将通过单击“下一步”按钮来提前决定要完成什么样的工作。如果您是初学者，那么首先请看下面的代码结构。然后按照下面的说明进行操作，这将帮助您更好地理解。
var nextSlide = function() {
if(count < items) {
slideList.style.left = “-” + count * sliderWidth + “px”;
count++;
}
else if(count = items) {
slideList.style.left = “0px”;
count = 1;
}
};正如我们所见，在 nextSlide 变量中，我们存储了 Next 按钮的工作方式。
首先，我们添加了 value if (count <items) 此代码将在图像数量超过 count 时起作用。
使用 else if (count = items) 我们已经确定了如果前面的函数不起作用会发生什么。如果图像和计数都相等，则滑块不会发生变化。
'count' 是您点击按钮的次数。如果您单击该按钮一次，则计数值为一。如果一次单击三次，则该帐户的值为 3。
我们已经决定了如果我们点击 Next 按钮将会发生什么样的变化。现在我们将实现上一个按钮。
类似地，我们已经确定了如果您单击上一个按钮会产生什么样的效果。
var prevSlide = function() {
if(count > 1) {
count = count – 2;
slideList.style.left = “-” + count * sliderWidth + “px”;
count++;
}
else if(count = 1) {
count = items – 1;
slideList.style.left = “-” + count * sliderWidth + “px”;
count++;
}
};确定单击此自动图像滑块中的上一个和下一个按钮时将产生何种效果。现在我们将这些效果与两个按钮相关联。
正如我之前所说，我们已经将 Next 按钮的工作方式存储在名为“next Slider”的常量中。下面我们已经指示如果您单击“下一步”按钮，该常量将起作用。
next.addEventListener(“click”, function() {
nextSlide();
});我们已经在“prevSlide”中保存了对上一个按钮起作用的内容。下面我们已经说明，如果您单击上一个按钮，该常量将起作用。
prev.addEventListener(“click”, function() {
prevSlide();
});由于这是一个自动图像滑块，在这种情况下，我已安排图像自动更改。这里我使用了 5000 即 5 秒。这意味着图像将每 5 秒更改一次。如果您希望图像每 2 秒更改一次，请在此处使用 2000 而不是 5000。
setInterval(function() {
nextSlide()
}, 8000);
};
window.onload = function() {
responsiveSlider();
}希望您从本教程中了解到我是如何使用 HTML CSS 和 JavaScript 代码创建这个漂亮的自动图像滑块的。如果您想下载所需的源代码，可以使用下面的下载按钮。
如果您对如何制作此自动图像滑块有任何疑问，那么您绝对可以通过评论让我知道。

Как сделать автоматический слайдер изображений в Html, CSS, Javascript
В этой статье вы узнаете, как создать автоматический слайдер изображений с помощью HTML CSS и кода JavaScript. Ранее я поделился с вами еще многими типами ручных и автоматических слайдеров изображений . Как и другие проекты, я надеюсь, вам понравится этот дизайн.
Слайдер изображений — это распространенный веб-элемент, который в настоящее время используется на многих веб-сайтах. Он в основном используется для слайд-шоу на главной странице сайта. Этот тип автоматического слайд-шоу изображений также используется для организации большого количества изображений в галерее. Если вы хотите узнать больше о javascript, ознакомьтесь с моими лучшими проектами HTML, CSS и javascript .
Существует два типа ползунков изображений: автоматический и ручной. В случае автоматического ползунка изображения изображение будет автоматически меняться через равные промежутки времени. В случае с мануалом менять изображение нужно с помощью кнопок Next и Previous.
Автоматический слайдер изображений
При этом изображение можно менять автоматически и вручную. Это означает, что он автоматически изменит изображение, и вы также можете изменить изображение, используя кнопки «Далее» и «Предварительный просмотр» по отдельности.
Дизайн можно создать только с помощью HTML и CSS, но в данном случае я использовал программный код JavaScript.
Если вы хотите узнать, как работают эти автоматические слайд-шоу изображений , вы можете посмотреть живую демонстрацию ниже. Ниже я дал исходный код, так что вы можете скопировать их, если хотите. Вы также можете скачать код с помощью кнопки загрузки внизу статьи.
Как вы можете видеть в демо выше, это очень простой слайдер изображений с автоматической и ручной сменой изображений.
В этом случае я использовал в общей сложности пять изображений, но вы можете использовать гораздо больше, если хотите. Изображение будет меняться автоматически каждые 5 секунд. Также есть две кнопки для смены изображения.
Автоматический слайдер изображений в HTML, CSS и Javascript
Если вы знаете основы HTML, CSS и JavaScript, вы легко разберетесь в этом дизайне. Чтобы создать этот автоматический слайдер изображений, сначала вам нужно создать файл HTML и CSS.
В данном случае я не создавал отдельный файл JavaScript, но вы можете создать отдельный файл, если хотите.
Шаг 1: Создайте базовую структуру слайдера
Я использовал небольшой код HTML и CSS ниже, чтобы создать фон для этого слайдера. В этом случае я использовал ползунок высотой 256 пикселей и шириной 500 пикселей.
Я не использовал разные цвета фона. Если вы видели демонстрацию, вы поймете, что вокруг этого слайда была использована тень, для которой я использовал box-shadow: 0 0 30px rgba(0, 0, 0, 0.3) здесь.
<div id=”slider”>
</div>
body {
margin: 10%;
}
#slider {
position: relative;
width: 500px;
height: 265px;
overflow: hidden;
box-shadow: 0 0 30px rgba(0, 0, 0, 0.3);
}Шаг 2: Добавьте необходимые изображения
Я добавил изображения в этот автоматический слайдер изображений, используя приведенный ниже код, и разработал эти изображения. Я использовал в общей сложности пять изображений, которые вы можете увеличивать или уменьшать по своему усмотрению.
Если вы внимательно посмотрите на приведенный ниже код CSS, вы поймете, что я использовал Slider Ul Width 10000%.
Вы можете задаться вопросом, почему я использовал здесь 10 000%. Внимательно посмотрите на изображение ниже, чтобы понять, почему и как работает этот ползунок.
<ul id=”slideWrap”>
<li><img src=”img1.jpg” alt=””></li>
<li><img src=”img2.jpg” alt=””></li>
<li><img src=”img3.jpg” alt=””></li>
<li><img src=”img4.jpg” alt=””></li>
<li><img src=”img5.jpg” alt=””></li>
</ul>В этом случае высота изображения составляет 256 пикселей, а ширина — 500 пикселей. Конечно, в этом случае вы будете использовать одинаковый размер каждого изображения.
#slider ul {
position: relative;
list-style: none;
height: 100%;
width: 10000%;
padding: 0;
margin: 0;
transition: all 750ms ease;
left: 0;
}
#slider ul li {
position: relative;
height: 100%;
float: left;
}
#slider ul li img{
width: 500px;
height: 265px;
}Шаг 3. Добавьте кнопки «Предыдущая» и «Далее»
Теперь мы добавим к этому слайдеру кнопки Previs и Next. Приведенный ниже код HTML и CSS помог добавить и спроектировать эти две кнопки.
<a id=”prev” href=”#”>≪</a>
<a id=”next” href=”#”>≫</a>
#slider #prev, #slider #next {
width: 50px;
line-height: 50px;
border-radius: 50%;
font-size: 2rem;
text-shadow: 0 0 20px rgba(0, 0, 0, 0.6);
text-align: center;
color: white;
text-decoration: none;
position: absolute;
top: 50%;
transform: translateY(-50%);
transition: all 150ms ease;
}Шаг 4: Определите точное расположение двух кнопок
Я использовал небольшой CSS ниже, чтобы разместить эти две кнопки на своих местах. Я оставил кнопку «Предварительный просмотр» на расстоянии 10 пикселей от левого края.
Я оставил следующую кнопку на расстоянии 10 пикселей от правого края. В результате эти две кнопки расположены по обе стороны от ползунка.
#slider #prev {
left: 10px;
}
#slider #next {
right: 10px;
}Я использовал следующий код CSS, чтобы использовать небольшой эффект наведения на фоне этих двух кнопок.
#slider #prev:hover, #slider #next:hover {
background-color: rgba(0, 0, 0, 0.5);
text-shadow: 0;
}Шаг 5. Активируйте ползунок изображения, добавив код JavaScript.
Пока мы его только оформили, теперь реализуем смену изображения этого слайдера.
var responsiveSlider = function() {
var slider = document.getElementById(“slider”);
var sliderWidth = slider.offsetWidth;
var slideList = document.getElementById(“slideWrap”);
var count = 1;
var items = slideList.querySelectorAll(“li”).length;
var prev = document.getElementById(“prev”);
var next = document.getElementById(“next”);
window.addEventListener(‘resize’, function() {
sliderWidth = slider.offsetWidth;
});Прежде всего, мы заранее определимся, какая работа будет выполнена, нажав на кнопку «Далее». Если вы новичок, то прежде всего посмотрите на структуру кода ниже. Затем следуйте приведенным ниже объяснениям, которые помогут вам лучше понять.
var nextSlide = function() {
if(count < items) {
slideList.style.left = “-” + count * sliderWidth + “px”;
count++;
}
else if(count = items) {
slideList.style.left = “0px”;
count = 1;
}
};Как мы видели, в переменной nextSlide мы сохранили, как будет работать кнопка «Далее».
Во-первых, мы добавили значение if (count <items), этот код будет работать, когда количество изображений больше, чем count.
С помощью else if (count = items) мы определили, что произойдет, если предыдущая функция не сработает. Если и изображение, и количество одинаковы, то слайдер не изменится.
'count' - это количество раз, когда вы нажали на кнопку. Если вы нажмете на эту кнопку один раз, значение счетчика будет равно единице. Если вы нажмете три раза одновременно, значение учетной записи равно 3.
Мы решили, какие изменения произойдут, если мы нажмем кнопку «Далее». Теперь мы реализуем предыдущую кнопку.
Точно так же здесь мы определили, какой эффект будет работать, если вы нажмете на предыдущую кнопку.
var prevSlide = function() {
if(count > 1) {
count = count – 2;
slideList.style.left = “-” + count * sliderWidth + “px”;
count++;
}
else if(count = 1) {
count = items – 1;
slideList.style.left = “-” + count * sliderWidth + “px”;
count++;
}
};Определение того, какой эффект будет работать при нажатии кнопок «Назад» и «Далее» в этом автоматическом слайдере изображений. Теперь мы свяжем эти эффекты с двумя кнопками.
Как я уже говорил ранее, мы сохранили то, как кнопка «Далее» будет работать, в константе под названием «следующий слайдер». Теперь ниже мы указали, что если вы нажмете кнопку «Далее», эта константа будет работать.
next.addEventListener(“click”, function() {
nextSlide();
});Мы сохранили то, что работает на предыдущей кнопке, в «prevSlide». Теперь ниже мы указали, что если вы нажмете на предыдущую кнопку, эта константа будет работать.
prev.addEventListener(“click”, function() {
prevSlide();
});Поскольку это автоматический слайдер изображений , в данном случае я устроил автоматическое изменение изображения. Здесь я использовал 5000 т.е. 5 секунд. Это означает, что изображение будет меняться каждые 5 секунд. Если вы хотите, чтобы изображения менялись каждые 2 секунды, используйте здесь 2000 вместо 5000.
setInterval(function() {
nextSlide()
}, 8000);
};
window.onload = function() {
responsiveSlider();
}Надеюсь, вы узнали из этого урока, как я создал этот красивый автоматический слайдер изображений , используя код HTML CSS и JavaScript. Если вы хотите загрузить необходимый исходный код, вы можете использовать кнопку загрузки ниже.
Если у вас есть какие-либо проблемы с пониманием того, как сделать этот автоматический слайдер изображений, вы обязательно можете сообщить мне об этом в комментариях.

Pdf2gerb: Perl Script Converts PDF Files to Gerber format
pdf2gerb
Perl script converts PDF files to Gerber format
Pdf2Gerb generates Gerber 274X photoplotting and Excellon drill files from PDFs of a PCB. Up to three PDFs are used: the top copper layer, the bottom copper layer (for 2-sided PCBs), and an optional silk screen layer. The PDFs can be created directly from any PDF drawing software, or a PDF print driver can be used to capture the Print output if the drawing software does not directly support output to PDF.
The general workflow is as follows:
- Design the PCB using your favorite CAD or drawing software.
- Print the top and bottom copper and top silk screen layers to a PDF file.
- Run Pdf2Gerb on the PDFs to create Gerber and Excellon files.
- Use a Gerber viewer to double-check the output against the original PCB design.
- Make adjustments as needed.
- Submit the files to a PCB manufacturer.
Please note that Pdf2Gerb does NOT perform DRC (Design Rule Checks), as these will vary according to individual PCB manufacturer conventions and capabilities. Also note that Pdf2Gerb is not perfect, so the output files must always be checked before submitting them. As of version 1.6, Pdf2Gerb supports most PCB elements, such as round and square pads, round holes, traces, SMD pads, ground planes, no-fill areas, and panelization. However, because it interprets the graphical output of a Print function, there are limitations in what it can recognize (or there may be bugs).
See docs/Pdf2Gerb.pdf for install/setup, config, usage, and other info.
pdf2gerb_cfg.pm
#Pdf2Gerb config settings:

How to Custom Range Slider using HTML CSS & JavaScript
How to Custom Range Slider using HTML CSS & JavaScript
You will learn how to build a Custom Range Slider using HTML CSS and JavaScript. Custom Range Slider We see it in different types of e-commerce websites or different types of business websites. This type of HTML range slider is used to select a specific value in the slider.
This is a kind of input function of HTML. HTML has many types of inputs like text, password, file, slider, etc. This type of Custom Range Slider has a minimum and maximum value. The user can select any one of those values.
This type of range slider with min and max values is very important for an eCommerce site. I have used animation in this Custom Range Slider. The button that changes the value is designed with CSS. Emojis are used instead of buttons.
How to Create Custom Range Slider with HTML CSS
The emoji in the slider can rotate 360 degrees. The emoji will be at 0 degrees at the slider minimum value. It will rotate when you change the position of the emoji. If you are a beginner then this project (Custom Range Slider using HTML CSS) is very important for you.
First, we created the basic structure of the slider using HTML. Then JavaScript has been used to activate this Custom Range Slider.
This slider can be used in addition to JavaScript. However, JavaScript is important for activating the display. The value of the display will change when you change the position of the button on the slider.
To make this custom range slider HTML CSS you need to have a basic idea about HTML CSS. I have given a demo that will help you to know more about this custom range slider.
Step 1: Basic structure of Custom Range Slider
Now is the time to create the basic structure of the Custom Range Slider. We know that Range Slider is created using input function. Here I first created Custom Range Slider using input and designed using some amount of CSS.
With this, a small box has been created using the level. All information can be found in this box. This means that the value of this display will change when you change the position of the slider button.
<label for=”slider”>0</label>
<input id=”slider” name=”slider” type=”range” value=0>
html,
body {
margin: 0;
height: 100%;
}
body {
display: flex;
justify-content: center;
align-items: center;
background-color: #1e76d0;
}
Step 2: Design a value viewing display
Now I have designed the level i.e. the following codes have been used to design the value view display. I made a small box with a white background color. The color blue of the text is used here.
label {
background: #eee;
position: absolute;
border-radius: 5px;
box-shadow: 2px 2px 4px rgba(0,0,0,0.4);
padding: 12px;
margin-left: -50px;
margin-top: -170px;
font-family: Roboto, ‘Helvetica Neue’, Arial;
font-size: 24px;
width: 75px;
text-align: center;
color: #2968bb;
font-weight: bold;
content: ”;
}
Step 3: Use images instead of slider buttons
Now the Custom Range Slider has been designed. Here the transparent background of the slider is used. Later I used a different background for this. An emoji is used here instead of the Range Slider button.
As I said before, an emoji has been used to enhance beauty. This emoji will basically act as a button. We know that in the case of a normal Range Slider the button can be relocated. Here too the value of the range will be changed by relocating the image.
As mentioned earlier this button can rotate 360. But that work has been done with the help of JavaScript.
input[type=”range”] {
-webkit-appearance: none;
background: transparent;
width: 90%;
max-width: 500px;
outline: none;
}
input[type=”range”]:focus,
input[type=”range”]:active{
border: 0;
outline: none;
}
input[type=”range”]::-webkit-slider-thumb {
border: none;
height: 40px;
width: 40px;
background-color: transparent;
background-image: url(“https://cdn.pixabay.com/photo/2020/09/14/18/34/amazed-5571740_1280.png”);
background-position: 0 0;
background-size: cover;
transform: scale(1.9) rotateZ(var(–thumb-rotate, 10deg));
cursor: pointer;
margin-top: -15px;
-webkit-appearance: none;
}
input[type=”range”]::-webkit-slider-thumb:active {
background-position: 100% 0px;
transform: scale(2) rotateZ(var(–thumb-rotate, 10deg));
}
Step 4: Design the runnable track of the Range Slider
Now this slider has created a runnable track. That means the background of the slider has been designed. The background is made in white color on which the image will continue.
input[type=”range”]::-webkit-slider-runnable-track {
width: 100%;
height: 20px;
background: #eee;
border-radius: 10px;
box-shadow: 2px 2px 4px rgba(0,0,0,0.4);
cursor: pointer;
-webkit-appearance: none;
}
Step 5: Activate Custom Range Slider with JavaScript
Now is the time to activate the display in this slide and arrange the emoji to rotate 360 degrees. As a result, changing the position of the image will change the value of the display. With this, the emoji will rotate 360 whenever it is changed.
First I set the input and level, that is, the constant of the image and the display, one by one. Because we can’t use any HTML function directly in JavaScript.
const input = document.querySelector(“input”);
const label = document.querySelector(“label”);
input.addEventListener(“input”, event => {
const value = Number(input.value) / 100;
input.style.setProperty(“–thumb-rotate”, `${value * 720}deg`);
label.innerHTML = Math.round(value * 50);
});
Hopefully from this tutorial, you have learned how to create Custom Range Slider Using HTML CSS, and JavaScript. If there is any problem while making this Range Slider, you can definitely let me know by commenting.
