The operating environment of this tutorial: windows7 system, html5 version, DELL G3 computer.
The difference between html5 and html:
1. In the document type declaration
In the document declaration, html has a long code, And it is difficult to remember this code, but html5 is different. There are only simple declarations, which is also easier for people to remember and is more streamlined. For example:
html： <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" " http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd" <html xmlns="http://www.w3.org/1999/xhtml">
html5:
<!DOCTYPE html>
2. In terms of structural semantics
html4.0: There is no tag that reflects structural semantics. We usually name it like this :60462f285538ec7c7020ffc11063dae716b28748ea4df4d9c2150843fecfba68;
html5: It has great advantages in semantics. Provides some new html5 tags, such as: 1aa9e5d373740b65a0cc8f0a02150c53, c787b9a589a3ece771e842a6176cf8e9, 23c3de37f2f9ebcb477c4a90aac6fffd, 15221ee8cba27fc1d7a26c47a001eb9b, c37f8231a37e88427e62669260f0074d...
3. Compared with html, HTML5 has powerful new features
(1) Powerful drawing function
There may be some animations or pictures, which can be achieved in HTML5 through the powerful drawing function and JS. But it doesn't work in html4.0.
2) Add a new video tag
Maybe in html4.0, if we want to insert a video, we also need to quote a long section of code. But in the case of html5. We only need to use it for a video tag.
