What is a WordPress Theme?
To put it simply, a WordPress theme is what gives your site its style and function. Basically a theme tells your WordPress website to look and behave a certain way. Your theme will include a whole slew of different files that are responsible for things such as building the site header, the footer, etc. One of the most important files in a theme is the stylesheet. This file controls the look of your custom WordPress website: colors, fonts, etc. WordPress themes can range from simple to extremely complex. They are usually written with particular needs in mind which is why there are so many available.
