Document title

The contents of the document.

HTML tag

HTML tag

HTML tag

HTML tag

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).

Differences between HTML 4.01 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."

Attribute

New: a new attribute in HTML5.

The attribute value description manifestNewURL defines a URL on which the document's cache information is described. Xmlns http://www.w3.org/1999/xhtmlHTML does not support it. Only XHTML supports it. Specify the namespace attribute of the XML (use this attribute if you need your content to conform to XHTML. ).

HTML tag

Global attribute

Tags support the global properties of HTML.
