Introduction to source code layout of HTML pages

XHTML specification: it must be in lower case, with the start and end tags, and double quotation marks for attributes.

HTML specification: It is case-insensitive and has the start and end tags. You can also put the end tag in the start tag, for example, <input type = 'text'/>. Double quotation marks and single quotation marks are available for attributes (must be paired ).

 

The root node of the HTML page. The code information of the page is stored in this node.

Head> node: head node. It contains the following subnodes:

Mete> tag: provides meta-information of a page, such as a page keyword;

Title> tag: the title of the page;

Script> tag: the area where Css and JavaScript code are generally stored;

Body> node: The content area of the page, which stores html Element Information.

Div> tag: stores all element controls.

Script> tag: Because the Html page is loaded from top to bottom, the content is not displayed once after loading, but the content is loaded and displayed simultaneously.
