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.

Highlight your code with beautiful highlighters.

Code Snippets in Comments plugin extends the Comments function by show code in highlighting without modifying the saving of comments in database.
By default Code Snippets in Comments plugin using Prism JavaScript Library as the code highlighter for its fast and light property.
Code Snippets in Comments plugin also support with two famous plugins, Prismatic and Code Syntax Block, automatically set the code highlighter with these two plugin setting.
And I suggest just using one of these code highlighter plugin.
One more function is that Code Snippets in Comments plugin add a new code input bar below comment textarea box, let visitor type their code with problem more easier.
