WordPress uses “themes” to determine the overall design of a site including the color, graphics, layout, and even the fonts used. Nowadays, you can find thousands of themes to choose from. Some are free to use, some are paid.
A WordPress Theme also called WordPress template is a ready made layout that can be used to define the overall look and feel of your site. It is a pre-designed template done by a “WordPress theme designer”. The php and html codes are already done by a coder or a web programmer.
All you have to do is install it on your dashboard and you will get a predefined site layout complete with sidebar or widget positions including the main website graphics like, header, logo or footer.
WordPress users may install and switch between themes. 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. The PHP and HTML code in themes can also be edited for more advanced customizations. – Wikipedia.
