How to highlight examples the source code or syntax in Joomla? There are many extensions on the official website, but for some reason they are not satisfied. This is a new plugin for source code, syntax highlight in Joomla - Prism.
The plugin uses the javascript-library Prism for highlight. All you need is just install the plugin, activate, select a theme. Done!

Further in the text of the material, you can use the code:

<pre class="line-numbers" data-start="1"><code language="language-xxx">p { color: red; }</code></pre>

where:
line-numbers – line numbering will be use;
data-start – start value for counter(can be negative);
language-css – language code. Language codes.

Do not use a <pre> tag if do not want block highlight.
