This article is about how tags define what to use in HTML. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

HTML tag

Example

Simple HTML5 document:

Document title

The contents of the document.

Browser support

All major browsers support tags.

Label definition and instructions for use

The tag informs the browser that this is an HTML document.

Tags are the outermost elements in an HTML document.

Tags are containers for all other HTML elements (except tags).

The difference between HTML4.01 and HTML5

In HTML5, a new attribute has been added: manifest.

The difference between HTML and XHTML

The xmlns attribute is required in XHTML, but not in HTML.

However, even if the xmlns attribute is not used in the XHTML document, the HTML validator on the W3C will not report an error. This is because "xmlns= http://www.w3.org/1999/xhtml" is a fixed value, which is added to the tag even if you do not include it."

Global attribute

Tags support the global properties of HTML.
