Theme

In WordPress, your choice of a theme is the most fundamental or simplest way to customize your blog.

A theme is a collection of templates that work together to produce a specific and consistent display layout design throughout your blog. The style template uses CSS to change the look of your blog.

Starting with WordPress’ Classic theme, themes implement a variety of optional PHP templates that change the functionality of your blog. Not all themes are the same, some use a lot more templates than others do. And, some have more SEO than others are.
