True or False: Knowing HTML and CSS is necessary to edit contents of a WordPress site.

The assertion that knowing HTML and CSS is necessary to edit contents of a WordPress site is not entirely accurate. WordPress is designed to be user-friendly and allows users to edit content through a graphical interface known as the block editor or visual editor. This means that users can create and modify posts, pages, and other content without needing to know any coding languages.

While having knowledge of HTML and CSS can enhance a user's ability to customize the design and layout of a WordPress site further, it is not a requirement for basic content editing. Users can change text, add images, and manage other content elements using the built-in tools within WordPress. Therefore, it is possible for someone to effectively use WordPress without any coding knowledge at all, making the statement false.
