FV Code Highlighter


Do you have a lot of code on your blog, and want to make it more readable? Then this is the plugin for you!
This plugin supports the highlighting of PHP, (x)HTML, JavaScript, CSS and XML. The default highlighter
color scheme uses the same colors Adobe’s Dreamweaver is using. This makes it easy for your visitors to
recognize what type of codes you wrote and quickly read through them.
Want to modify the default color scheme? No problem! With a little bit of knowledge about CSS, you can
completely customize the output of the plugin.


  • PHP Code with dark mode enabled
  • The configuration page.
  • PHP Code with notepaper background and toolbox
  • General Code
  • CSS Code
  • HTML Code with embedded CSS and Javascript
  • JavaScript Code
  • PHP Code


This section describes how to install the plugin and get it up & running.

  • PHP 7.0 or higher

It works, but requires you to format your own CSS to make it look pretty at all. I prefer Prismatic and Simple Code Highlighter.
