An Overview of HTML
HTML is the hypertext markup language used on the World Wide Web.
HTML documents are plain-text (ASCII) files that can be created with any text editor. You can also use word processing software as long as you save your document as “text only with line breaks.”
HTML commands are not case sensitive; <title> is equivalent to <TITLE>.
An element is a fundamental component of the structure of a text document. Examples of elements: heads, paragraphs, tables, lists, etc. Elements can contain plain text, other elements, or both.
To denote elements in an HTML document you use tags.
