HTML as a markup language, is a variety of tags to mark the content of the Web page. We learn HTML is mainly to learn HTML tags.
So what is a label?
# 1, in the HTML stipulation label uses the English angle brackets namely ' < ' and ' > ' to wrap up, such as ' # 2. The tags in the HTML are usually paired, divided into the start and end tags, the end tag is more than the start tag a '/', the start tag and the end tag between the contents of the label. #3, some of the label function is relatively simple, using a label, this label is called the closed and label, such as:<br/>
tags in html are stored in a text file and are organized according to the following fixed document structure:
<! DOCTYPE html>Parts of the HTML document structure are explained
# 1, <! DOCTYPE Html> is a document declaration that must be written in the first line of the HTML document, before the #2, #3, #4, the content between <body> and </body> tags is the main content of the page, will eventually appear in the browser.Relationship between HTML tags

The format of comments in HTML:
<!--here is the content of the note--Note: You can use carriage return to wrap directly in comments.
And we're used to wrapping up the HTML code with the annotated tag. Such as:
