Joomla contains thousands of verified third-party extensions, which can be found on Joomla extensions directory (i.e., extensions.joomla.org). There are several high-end templates available, and most of them are free to use. However, there is also an option to use paid themes that come with support. Templates are used to get different types of user interfaces, which allow us to change the colors, font style, layouts, and features, etc.
