This plugin hasn’t been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.



This is a very basic and crude highlighter. It doesn’t highlight keywords, strings, or any of the things fancy highlighters everywhere else do. Simply, this highlights every alternate line of code with a separate background colour.

Requires the jQuery framework, but only to select the <pre><code> blocks. If you know what you’re doing, you can remove the code to include the framework, and fix the code from the plug-in editor page.

Known Bugs

0.7: Still no keyword highlighting. Will skip 0.8, 0.9 and include that in 1.0.
