Talking about HTML5

　The difference between HTML5 and HTML:

　　1. On the document type declaration

html:<! DOCTYPE HTML PUBLIC "-//W3C//DTD XHTML 1.0 transitional//en" "Http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd ">

　　

html5:<! DOCTYPE html>

　　2. In structural semantics

HTML: There is no structure semantic label, we are usually named <div id= "header" ></DIV> This represents the head of the Web site.

HTML5: There is a great advantage in semantics. Provides a number of new semantic tags, such as:

　　HTML5 Common structure Tags: article,aside,figcaption,figure,footer,header,hgroup,nav,section,time

The <article> tag defines the external content, which can be a new article.

<aside> tags define content other than article, and aside content can be used as the sidebar for the article.

The <figcaption> tag defines the caption of the figure element.

The <figure> tag is used to group elements, using the figcaption element to add headings to the element groups.

The <footer> tag defines the section or footer of the document.

The

<nav> tags define the part of the navigation link.

<section> tags define the sections (section, section) in the document. such as chapters, headers, footers, or other parts of the document.

The <time> tag defines the date or time, or both.

HTML5 Advantages:

　　1. Network standards

2. Multi-device cross-platform

3. Self-adapting web design

4. Instant Updates

cons :　　 The standard is not well supported by the browser. Due to the introduction of new tags, there is a lack of a unified data description format between browsers, resulting in poor user experience.
