Themes allow users to change the look and functionality of a WordPress website or installation without altering the informational content. Themes may be installed by using the WordPress “Dashboard” administration tool, or by uploading theme folders via FTP.[9] The PHP and HTML code in themes can also be edited for more advanced customizations.[/pwal]


One very popular feature of WordPress is its rich plugin architecture which allows users and developers to extend its abilities beyond the features that are part of the base install; WordPress has a database of over 18,000 plugins[10] with purposes ranging from SEO to adding widgets.


Widgets are small modules that offer users drag-and-drop sidebar content placement and implementation of many plugins‘ extended abilities. Widgets offer wordpress developers to add functionality to their site. These small widgets can be used to add functionality such as a slideshow, facebook like box, small news slider etc.
