Syntax Highlighter HTML5 Web Component Based on Lea Verou’s Prism.JS

AcidJs.XHilite is a syntax highlighter HTML5 Web Component, based on Lea Verou‘s Prism.JS and wrapped as a custom tag with support for multiple languages and both declarative and async loading of the code to be highlighted.


<acidjs-xhilite language="javascript" height="200" width="400">
function sayHi() {
    return "Hello, World"!;

Recently I my HTML5, CSS3 and JavaScript Experiments website received a major facelift and as a next step and I am planning to replace the syntax highlighter I am currently using with AcidJs.XHilite.

HTML Attributes of the Tag

Any native HTML attribute (id, class, data-*, style, etc.) is supported, plus the component-specific:

  • language – The language to highlight, for example language="javascript". Default: "markup" (usable with HTML, SVG, XML, etc.). Check for a complete list of supported languages.
  • width – Optional width in pixels of the code block, for example: width="600".
  • height – Optional height in pixels of the code block, for example: height="200".
  • src – Instead of adding the code to highlight in the tag, you can specify path to the file which content needs to be highlighted, for example: src="example.js"

JavaScript Methods of the Tag

Native JavaScript methods (document.getElementById, document.querySelector, etc. as well as their jQuery or other libraries aliases).
