Every HTML document must contain a few basic things. The HTML header, a heading, and a body. Below is an example of all the necessary pieces one may use to shape a web document. All documents need these things. The HTML structure is very simple.
Most commands have a starting point and an ending point.
Most HTML commands follow this simple format. Only a few stand alone. It goes at the very beginning and end of every document, and everything else lies inside of it. This is important to formatting the text, because HTML does not pay any attention to line spaces or anything. Within a link command can be placed other text formatting and image commands to define how you want you link to be displayed.
