Web documents can contain text, images, animations, audio, PostScript, and other file formats.
Most Web documents consist primarily of text with other types of files embedded inside.
Formatting a document means that the client reads the HTML codes, interprets them, and determines how the document should look online. Clients vary on how they depict different elements on the screen, although most clients follow standard display conventions. HTML codes identify the elements of a file such as headings, paragraphs, or lists. Most tags are paired with the closing tag including a slash. A hyperlink to another file is created with a tag that includes complete information about the document's location.
