A WordPress theme is a collection of files that work together to produce the visual look of your website. These files are called template files. A theme modifies the way the site is displayed, without modifying the underlying software.
Where can I find themes?
The WordPress Theme Repository is the official site to search for WordPress themes. Every theme in this directory is reviewed by a dedicated team and tested against a wide range of rules, all of which are designed to ensure a secure and pleasant experience for the theme user.
Among the thousands of themes in the directory, you can easily find the right one for your site using the advanced search feature that uses filters for layout, subject and a specific theme’s features.
There are also sites outside of WordPress.org where you can find themes for your site, but the most reliable source is WordPress.org itself.
What makes a good theme?
When considering what theme to use for your site, it’s a good idea to have a general idea of what you want your site to look like.
The WordPress.org theme directory allows you to filter themes by features, layout, and subject. Will you have a photo blog or an e-commerce site? Do you want one, two, or three columns on your site? How about support for full site editing or a custom header?
You don’t need to be able to answer all of these questions, but the more you know, the easier it is to narrow down your choices. As you search through the different themes available, you can click on Details and Preview to find out more information about each theme, including things like what version it’s on and if there are any ratings.
Version updates and ratings can give a good sense of the overall experience others have had with this theme, as well as its support for updates to the core WordPress software itself. Just like WordPress, themes need to be updated in order to take advantage of new features, and for security fixes.
