WordPress themes are a way to change the look and feel of a WordPress site.
Some people build their website from scratch, while others prefer to use a pre-built theme. Themes can be used in countless creative ways to make your site look unique. Themes make the process of designing your site much easier and faster, as it can take many hours or days to hand code everything from scratch.
There are over 100,000 free themes available for download on WordPress.org alone! If you want more premium templates, hundreds of thousands more are available on sites like Themeforest and Creative Market. When you install a new theme, all the old content is replaced with that theme’s content automatically in just a few clicks!
