Some web developers love to show their work/code in their personal blogs for the users to learn. But problem is that, they can’t insert or highlight their code snippet in the editor directly. So, some developers have developed some very nice plugins to tackle this problem. Following are a list of best WordPress plugins to highlight code within your blog that I have personally tried.
1. CodeColor Plugin
This plugin allows you to highlight code or snippet within your blog with amazing styling. It supports many languages.
Color Customization in CSS file
Highlight colors included: Railscasts, Vibrant Ink, Twitlight, Mac Classic, Dawn, Slush & Poppies and Blackboard.
For large code highlight, there would appear scrolling.
Line numbers Support and music more.
2. Code Markup Plugin
This plugin will allow to highlight your code in an efficient way. It is compatible from WordPress 1.5 to latest version. This plugin helps you by escaping special HTML characters and tags so they display exactly as you enter through your input device. For example, if you will use normal code block with <em>, it will be displayed as emphasized text, but if you will use in HTML code block, it will be displayed as <em>.
3. Code Snippet Plugin
4. WP-SynHighlight Plugin
This is a WordPress plugin for highlighting your source code and works like BBCode tag. It would highlight everything you will put between BB code tags. The plugins support 116 programming languages via Geshi.
