$ paint examples

Replacing <pre> blocks with highlighted syntax

The replace command finds <pre> blocks on an html page and replaces them with highlighted blocks. The command doesn't change to the source file; it outputs a copy of the document.

Or use watch mode and highlighting will be updated every time you save the source file:

Each <pre> block needs a data-paint="language" attribute so paint knows what type of syntax to use. You can set options for all snippets on the cmd line, or apply settings individually for each snippet by setting data attributes. By default, CSS styles will be included in a style block above the syntax. You can change this behavior by breaking styles/content into two operations using some combination of --html-only / --css-only options or data-html-only / data-css-inline attributes.

Check this page before and after syntax highlighting:
