WordPress themes, essentially, are sets of files and folders that incorporate templates, CSS style sheets, and PHP programming language, among other elements. Their function is to give your website its unique and distinctive appearance. A WordPress theme defines the aesthetics and design of your website, and the appropriate selection can act as a true reflection of your brand.
There are numerous WordPress templates available to choose from when setting up your website and deciding its final look. WordPress, in its vast scope, provides a variety of preconfigured themes to facilitate the task. If, for any reason, none of these preconfigured themes meet your preferences or needs, you can always turn to the extensive WordPress theme directory to find an alternative that aligns with your vision.
