There are three parts of an HTML tag- the opening tag, the content, and the closing tag. You can also find some HTML tags with unclosed tags. 

A web browser reads an HTML tag from top to bottom, and from left to right. You can use these tags to create HTML documents and render their properties. For example, is the opening tag, whereas is the closing tag. Note that the closing tag has the same text as the opening tag, but has an additional forward slash (/) character. 

Each HTML tag has different properties which you can use for different purposes. An HTML file needs to consist of some essential tags. This helps the web browsers understand the differences between HTML and simple content. You can use as many tags according to your code requirements.
