The differences between HTML5 and HTML are as follows:
1. On the document type declaration, HTML has a long piece of code, which is difficult to remember. However, HTML5 is different, with only a simple declaration, which is convenient for people's memory and more concise. For example:
HTML:
& lt;! DOCTYPEhtmlPUBLIC"-// W3C//DTDXHTML1.0Transitional//EN"& quot;
http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"
< htmlxmlns=" http://www.w3.org/1999/xhtml"& gt;
html5：
<! DOCTYPEhtml>
2, on the Structural Semantics
html4.0: there is no tag reflecting the structural semantics, we usually name it like this: & lt; divid=" header"& gt;& lt;/ div>
HTML5: it has great advantage in semantics. Some new HTML5 tags are provided, such as: & lt; header>、& lt; nav>、& lt; article>、& lt; aside>、& lt; footer>...
3. Compared with HTML, HTML5 has powerful new functions
(1) powerful drawing function
maybe some animations or pictures can be realized in HTML5 through powerful drawing function and JS. But not in HTML 4.0
2) new video tag
maybe when we want to insert a video in html4.0, we need to refer to a long code. But in the case of HTML5. We only need to use one video tag
< videosrc=" Video address & quot& gt;& lt;/ video>
in general, HTML5 is an upgraded version of HTML with new tags and more functions
