Don't worry, it sounds much more complicated than it is. Basically, HTML is a way of telling the browser what to display on the screen and how to display it. To do so, it uses what are known as tags .
Tags are instuctions set into the text of the page that the browser responds to.
For example, I use a tag to tell the browser to place this text in boldface starting here, and it will continue until I tell it to stop, which I do here. The sa me can be used for italics and other ways of altering text. The first pair of tags in any HTML document is the tag which tells the browser that they page it is about to read is simply an HTML document in the first place. Everything else will be between these two tags. Next, the page is divided into a head and a body.
