Even for the novice, HTML is easy to use and involves adding codes to text documents. These codes tell the browser to show a certain word in bold, for example, or indicate the address of a linked page. This is a reserved character that Netscape and other browsers use to know how to format the text in a document.
Tags are also usually in pairs.
The first says that the following text, until the ending tag is met, is centered. Almost all tags that are used in pairs work with this precept. They also work just like parentheses in mathematical statements. You can nest them and have long strings contained between a single pair. Just don't forget to close every tag that you open.
