HTML Tag is a most important part in HTML Language. An HTML Tag carries all about HTML contents and this the main thing to maintain all of the codes in a web page. HTML Tag is the mother of an HTML document.
HTML tags are the hidden keywords within a web page that define how your web browser must format and display the content.
Most tags must have two parts, an opening and a closing part. For example, <html> is the opening tag and </html> is the closing tag. Note that the closing tag has the same text as the opening tag, but has an additional forward-slash ( / ) character. I tend to interperet this as the "end" or "close" character. There are some tags that are an exception to this rule, and where a closing tag is not required. The <img> tag for showing images is one example of this. Each HTML file must have the essential tags for it to be valid, so that web browsers can understand it and display it correctly. The rest of the HTML file can contain as little or as many tags as you want to display your content.
Example: <html>, </html>, <head>, </head>, <body>, </body>, <br>, <hr>, <marquee> etc.
All of the HTML Tags are described bellow...
