WordPress and Less
Nowadays, WordPress is not only used for weblogs; it can also be used as a content management system to build a website.
The WordPress system, written in PHP, has been split up into the core system, plugins, and themes. Plugins add additional functionalities to the system and themes handle the look and feel of a website built with WordPress. Plugins work independent of each other. Plugins are also independent of the theme, and the theme mostly does not depend on plugins either. WordPress themes define the global CSS for a website, but every plugin can also add its own CSS code.
WordPress theme developers can use Less to compile the CSS of themes and plugins.
