Is HTML5 still supported?

HTML5 is several years old now, and as the living standard of the language as a whole, it will only continue to get updated to work with the modern web.

Does HTML5 require closing tags?

A traditional HTML tag such as <p>, <div>, <section>, etc., had an opening tag and a closing tag. However, due to their fundamental structure, void components in HTML, such as images and links, do not technically require closing tags.
