HTML is a "tagged" formatting tool. Tags are usually paired and are not case-sensitive.

A tag may have addition attributes that further define how the tag affects the document in the browser. The are three parts needed when including an attribute:

  1. the name of the attribute
  2. the equal sign (=)
  3. the value enclosed in quotes

The document must be in text format, so use a text editor like Notepad or TextPad to write the document.
