An Introduction to CSS Variables

This article is part 1 out of 3 articles detailing CSS files. You can find links to the other two at the bottom of this page.

One of the biggest issues with writing large amounts of CSS is keeping things consistent. For example, in a large codebase a single color can be used hundreds of times in hundreds of places. This repetition makes maintenance difficult as a simple design tweak like changing a color can result in that change needing to be made in many, many places.

CSS pre-processors like Sass and Less attempt to solve this particular problem (and others) by including variables. Variables let you set common values like colors and sizes in a single place then reference the variable when you need to use those values. Now a simple color change only needs to be made in one place.

Modern CSS, though, is very powerful and CSS now has native support for variables. You don’t need any build tools or pipelines; they are just part of the language. The code you write is the code that the browser uses. Formally, variables are “custom properties” but are commonly referred to simply as variables. Let’s explore how they can be used and how they can make writing CSS a much better experience.

Declaring and Using Variables

One of the telling things about the name “custom properties” is that they are CSS properties. Since they are properties, they have to be declared within a CSS rule like any other property:

/* Nope! */
--brand-color: #003d7d;

.foo {
    /* Yep! */
    --brand-color: #003d7d;
}

To differentiate variables from standard properties, they must start with --. Any name can be used though, so long as you only use letters, numbers, and dashes. Remember that they are case-sensitive, so --foo and --Foo are not the same variable.

Variables are also part of the normal cascade of CSS properties. This effectively means that you will want to declare your global variables on the highest element in the document tree, which is almost always html. But if you have styles that apply to the html element and want to keep your variable declarations separate, a common practice is to use the :root pseudo-class:

:root {
    --brand-color: #003d7d;
}

The values of your variables can be many different things as basically any valid CSS value can be the value of a variable. Sizes and colors are just the beginning as entire border and background values can also be stored. You can also use the value from one variable to set another. The possibilities are endless.

:root {
    --brand-color: #003d7d;
    --spacing: 4px;
    --spacing-large: calc(var(--spacing) * 2);
    --border: 2px solid var(--brand-color);
    --info-icon-bg-image: url('data:/...');
}

In the code sample above, you probably noticed how we access the value of variables: the var() function. The first parameter to that function should be the variable you need the value from. The second (optional) parameter is used as a fallback value. This is useful if you are not sure if a variable has been set and can be used for all sorts of fun tricks.

:root {
    --some-color: #003d7d;
}

.widget {
    background-color: var(--some-color);
    font-size: var(--font-size, 16px);
}

In that example, since we did not declare a --font-size variable, var() will return 16px since that is the fallback value. Note that only the first value is considered the variable to evaluate and, like the values of variables, the fallback value can contain commas. For example, var(–foo, red, blue) defines a fallback of red, blue and not two separate fallback values.

📺 Demo

🔩 Basic Demo

// FButton #1
FButton(
  height: 40,
  alignment: Alignment.center,
  text: "FButton #1",
  style: TextStyle(color: Colors.white),
  color: Color(0xffffab91),
  onPressed: () {},
)

// FButton #2
FButton(
  padding: const EdgeInsets.fromLTRB(12, 8, 12, 8),
  text: "FButton #2",
  style: TextStyle(color: Colors.white),
  color: Color(0xffffab91),
  corner: FCorner.all(6.0),
)

// FButton #3
FButton(
  padding: const EdgeInsets.fromLTRB(12, 8, 12, 8),
  text: "FButton #3",
  style: TextStyle(color: Colors.white),
  disableStyle: TextStyle(color: Colors.black38),
  color: Color(0xffF8AD36),

  /// set disable Color
  disabledColor: Colors.grey[300],
  corner: FCorner.all(6.0),
)

By simply configuring text andonPressed, you can construct an available FButton.

If onPressed is not set, FButton will be automatically recognized as not unavailable. At this time, ** FButton ** will have a default unavailable status style.

You can also freely configure the style of FButton when it is not available via the disabledXXX attribute.

🎈 Corner & Stroke

// #1
FButton(
  width: 130,
  text: "FButton #1",
  style: TextStyle(color: Colors.white),
  color: Color(0xffFF7043),
  onPressed: () {},
  clickEffect: true,
  
  /// 配置边角大小
  ///
  /// set corner size
  corner: FCorner.all(25),
),

// #2
FButton(
  width: 130,
  text: "FButton #2",
  style: TextStyle(color: Colors.white),
  color: Color(0xffFFA726),
  onPressed: () {},
  clickEffect: true,
  corner: FCorner(
    leftBottomCorner: 40,
    leftTopCorner: 6,
    rightTopCorner: 40,
    rightBottomCorner: 6,
  ),
),

// #3
FButton(
  width: 130,
  text: "FButton #3",
  style: TextStyle(color: Colors.white),
  color: Color(0xffFFc900),
  onPressed: () {},
  clickEffect: true,
  corner: FCorner(leftTopCorner: 10),
  
  /// 设置边角风格
  ///
  /// set corner style
  cornerStyle: FCornerStyle.bevel,
  strokeWidth: 0.5,
  strokeColor: Color(0xffF9A825),
),

// #4
FButton(
  width: 130,
  padding: EdgeInsets.fromLTRB(6, 16, 30, 16),
  text: "FButton #4",
  style: TextStyle(color: Colors.white),
  color: Color(0xff00B0FF),
  onPressed: () {},
  clickEffect: true,
  corner: FCorner(
      rightTopCorner: 25,
      rightBottomCorner: 25),
  cornerStyle: FCornerStyle.bevel,
  strokeWidth: 0.5,
  strokeColor: Color(0xff000000),
),

You can add rounded corners to FButton via the corner property. You can even control each fillet individually。

By default, the corners of FButton are rounded. By setting cornerStyle: FCornerStyle.bevel, you can get a bevel effect.

FButton supports control borders, provided that strokeWidth> 0 can get the effect 🥳.

🌈 Gradient


FButton(
  width: 100,
  height: 60,
  text: "#1",
  style: TextStyle(color: Colors.white),
  color: Color(0xffFFc900),
  
  /// 配置渐变色
  ///
  /// set gradient
  gradient: LinearGradient(colors: [
    Color(0xff00B0FF),
    Color(0xffFFc900),
  ]),
  onPressed: () {},
  clickEffect: true,
  corner: FCorner.all(8),
)

Through the gradient attribute, you can build FButton with gradient colors. You can freely build many types of gradient colors.

🍭 Icon

FButton(
  width: 88,
  height: 38,
  padding: EdgeInsets.all(0),
  text: "Back",
  style: TextStyle(color: Colors.white),
  color: Color(0xffffc900),
  onPressed: () {
    toast(context, "Back!");
  },
  clickEffect: true,
  corner: FCorner(
    leftTopCorner: 25,
    leftBottomCorner: 25,),
  
  /// 配置图标
  /// 
  /// set icon
  image: Icon(
    Icons.arrow_back_ios,
    color: Colors.white,
    size: 12,
  ),

  /// 配置图标与文字的间距
  ///
  /// Configure the spacing between icon and text
  imageMargin: 8,
),

FButton(
  onPressed: () {},
  image: Icon(
    Icons.print,
    color: Colors.grey,
  ),
  imageMargin: 8,

  /// 配置图标与文字相对位置
  ///
  /// Configure the relative position of icons and text
  imageAlignment: ImageAlignment.top,
  text: "Print",
  style: TextStyle(color: textColor),
  color: Colors.transparent,
),

The image property can set an image for FButton and you can adjust the position of the image relative to the text, throughimageAlignment.

If the button does not need a background, just set color: Colors.transparent.

🔥 Effect


FButton(
  width: 200,
  text: "Try Me!",
  style: TextStyle(color: textColor),
  color: Color(0xffffc900),
  onPressed: () {},
  clickEffect: true,
  corner: FCorner.all(9),
  
  /// 配置按下时颜色
  ///
  /// set pressed color
  highlightColor: Color(0xffE65100).withOpacity(0.20),
  
  /// 配置 hover 状态时颜色
  ///
  /// set hover color
  hoverColor: Colors.redAccent.withOpacity(0.16),
),

The highlight color of FButton can be configured through the highlightColor property。

hoverColor can configure the color when the mouse moves to the range of FButton, which will be used during Web development.

🔆 Loading

FButton(
  text: "Click top loading",
  style: TextStyle(color: textColor),
  color: Color(0xffffc900),
  ...

  /// 配置 loading 大小
  /// 
  /// set loading size
  loadingSize: 15,

  /// 配置 loading 与文本的间距
  ///
  // Configure the spacing between loading and text
  imageMargin: 6,
  
  /// 配置 loading 的宽
  ///
  /// set loading width
  loadingStrokeWidth: 2,

  /// 是否支持点击自动开始 loading
  /// 
  /// Whether to support automatic loading by clicking
  clickLoading: true,

  /// 配置 loading 的颜色
  ///
  /// set loading color
  loadingColor: Colors.white,

  /// 配置 loading 状态时的文本
  /// 
  /// set loading text
  loadingText: "Loading...",

  /// 配置 loading 与文本的相对位置
  ///
  /// Configure the relative position of loading and text
  imageAlignment: ImageAlignment.top,
),

// #2
FButton(
  width: 170,
  height: 70,
  text: "Click to loading",
  style: TextStyle(color: textColor),
  color: Color(0xffffc900),
  onPressed: () { },
  ...
  imageMargin: 8,
  loadingSize: 15,
  loadingStrokeWidth: 2,
  clickLoading: true,
  loadingColor: Colors.white,
  loadingText: "Loading...",

  /// loading 时隐藏文本
  ///
  /// Hide text when loading
  hideTextOnLoading: true,
)


FButton(
  width: 170,
  height: 70,
  alignment: Alignment.center,
  text: "Click to loading",
  style: TextStyle(color: Colors.white),
  color: Color(0xff90caf9),
  ...
  imageMargin: 8,
  clickLoading: true,
  hideTextOnLoading: true,

  /// 配置自定义 loading 样式
  ///
  /// Configure custom loading style
  loadingWidget: CupertinoActivityIndicator(),
),

Through the loading attribute, you can configure Loading effects for ** FButton **.

When FButton is in Loading state, FButton will enter an unavailable state, onPress will no longer be triggered, and unavailable styles will also be applied.

At the same time loadingText will overwritetext if it is not null.

The click start Loading effect can be achieved through the clickLoading attribute.

The position of loading will be affected by theimageAlignment attribute.

When hideTextOnLoading: true, if FButton is inloading state, its text will be hidden.

Through loadingWidget, developers can set completely customized loading styles.

Shadow


FButton(
  width: 200,
  text: "Shadow",
  textColor: Colors.white,
  color: Color(0xffffc900),
  onPressed: () {},
  clickEffect: true,
  corner: FCorner.all(28),
  
  /// 配置阴影颜色
  ///
  /// set shadow color
  shadowColor: Colors.black87,

  /// 设置组件高斯与阴影形状卷积的标准偏差。
  /// 
  /// Sets the standard deviation of the component's Gaussian convolution with the shadow shape.
  shadowBlur: _shadowBlur,
),

FButton allows you to configure the color, size, and position of the shadow.

🍭 Neumorphism Style

FButton(

  /// 开启 Neumorphism 支持
  ///
  /// Turn on Neumorphism support
  isSupportNeumorphism: true,

  /// 配置光源方向
  ///
  /// Configure light source direction
  lightOrientation: lightOrientation,

  /// 配置亮部阴影
  ///
  /// Configure highlight shadow
  highlightShadowColor: Colors.white,

  /// 配置暗部阴影
  ///
  /// Configure dark shadows
  shadowColor: mainShadowColor,
  strokeColor: mainBackgroundColor,
  strokeWidth: 3.0,
  width: 190,
  height: 60,
  text: "FWidget",
  style: TextStyle(
      color: mainTextTitleColor, fontSize: neumorphismSize_2_2),
  alignment: Alignment.center,
  color: mainBackgroundColor,
  ...
)

FButton brings an incredible, ultra-high texture Neumorphism style to developers.

Developers only need to configure the isSupportNeumorphism parameter to enable and disable the Neumorphism style.

If you want to adjust the style of Neumorphism, you can make subtle adjustments through several attributes related to Shadow, among which:

shadowColor: configure the shadow of the shadow

highlightShadowColor: configure highlight shadow

FButton also provides lightOrientation parameters, and even allows developers to adjust the care angle, and has obtained different Neumorphism effects.
