What is HTML?

HTML or Hyper Text Mark-up Language  is the primary language for formatting web pages.With HTML you describe what a page should look like, what types of fonts to use, what color text should be, where paragraph marks come and many more aspects of the document. It consists of simple text  files (ASCII)  plus "tags" or codes. All HTML documents are written in the extension  of ".htm" or ".html" this tells the browser that it's looking at a  HTML document. HTML documents will not recognize the white space and line breaks unless they are used inside certain special tags which we'll describe later.That means you need not write it tidily. You can use spaces and tabs anyhow you like, and break lines anywhere.
 

Tags

All HTML documents are created by using a tags.Tags have beginning and ending identifiers to communicate to the browser the beginning and ending text that is to be formatted . Most of the tags  have an opening and a closing tag.There are some tags that do not have an ending tag . Each tag is enclosed  with the "less than" (i.e. <) and "greater than" (i.e. >) sign. The closing tag usually looks the exact same as the opening tag with the exception of the "forward slash" (i.e. /) that identifies it is a closing tag. The first word  between the angle brackets is the tag's name. Any further words and characters are the attributes.Tags are not case sensitive.
Formatting text using tags are described in Text control.
