In WordPress, a theme consists of a collection of files (stylesheets, graphics, and code) that dictate what your blog or website will look like. Depending on your theme, you can tweak everything from your site's layout to the link colors. While a theme can be thought of as a 'skin' for your site, they are incredibly powerful. Your website theme affects the appearance of your site, including the typography, layout, color scheme, and other design elements.

When you create a new WordPress website, it comes with a pre-installed theme, but you can change it in WordPress to match your industry and needs. The right theme can improve visitors' engagement, enhance the appearance of your website, and make it easier to use. Divi, Astra, OceanWP, etc., are the most popular and best WordPress themes available for download.
