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