The HTML tag, <HTML>, tells the browser that the document is written and marked up in standard HTML. The <HTML> tag is a paired tag, where <HTML> is the open tag and </HTML> is the close tag.

Web browsers ignore carriage returns, tabs, and extra spaces when the document is reformatted for display.

The <P> tag specifies a paragraph break.
See an example

The <BR> tag specifies a line break to mark the end of a line.
See an example

A good idea is to place all line break tags at the end of text lines and all paragraph tags in lines of their own.

The <PRE> tag specifies preformatted information and is a paired tag. The text displayed with the <PRE> tag is a different typeface.
