Not all HTML tags have a beginning and an end. It is common practice, however, to specify all tags in uppercase because they are easier to spot when editing an HTML document. The following sections describe the use of commonly used HTML tags. If HTML is new to you, I suggest that you read each section in sequence.

Web forms let a reader return information to a Web server for some prescribed action.
For example, suppose you collect names and email addresses so you can email information to people who request it. For each person who enters his or her name and address, you need to send some response back to them and to add the respondent's data to a data base. This processing of incoming data is done by a script or program executed on the web server. The forms themselves are not hard to code. They follow the same constructs as other HTML tags.
