Bleach Is an HTML Cleaning Library

Bleach

Bleach is an allowed-list-based HTML sanitizing library that escapes or strips markup and attributes.

Bleach can also linkify text safely, applying filters that Django's urlize filter cannot, and optionally setting rel attributes, even on links already in the text.

Bleach is intended for sanitizing text from untrusted sources. If you find yourself jumping through hoops to allow your site administrators to do lots of things, you're probably outside the use cases. Either trust those users, or don't.

Because it relies on html5lib, Bleach is as good as modern browsers at dealing with weird, quirky HTML fragments. And any of Bleach's methods will fix unbalanced or mis-nested tags.

The version on GitHub is the most up-to-date and contains the latest bug fixes. You can find full documentation on ReadTheDocs.

Commonly Used HTML Tags with Examples

HTML tags are keywords used in HTML to display web-pages with certain properties. They are further used for defining HTML elements. An HTML element consists of a starting tag, some content, and an ending tag. The web browser reads the HTML document from top to bottom, left to right. Each HTML tag defines a new property that helps in rendering the website.

HTML Tags

The ‘<>’ brackets contain an HTML tag. There are two types of HTML tags- empty tags or singleton tags and container tags. Singleton tags or empty tags do not contain any content such as an image or a paragraph and hence do not need to be closed, whereas container tags should be closed.

Syntax

1. Some Content

Examples of:

Empty tag:

Container tags:
