Web pages are written in the Hyper-Text Markup Language or HTML, a fairly simple and small collection of commands to format text. Most of an HTML file consists of text with a few markup tags , which affect how text looks and behaves. The structure of a page is very basic.
Many browsers display it outside the main body of the page for easy reference.
However, it may save you from annoying editing when browsers become less lenient. So if you just type text, you will see no paragraphs. There are many ways to make text stand out. Most formatting tags work in exactly the same way. These tags designate physical styles instead of logical ones .
