HTML text tags indicate the structure of HTML pages; that is, they indicate what role a text segment is playing in the page organization. Using these text tags you can indicate which text segments are headings, subheadings, lists, quotes, and paragraphs.
HTML line break tags can be used for poetry or other situations where you want text to appear on a separate line without any extra vertical space. Using a line break looks like this:
Mary had a little lamb
Its fleece was white as snow.
