HTML5 is an upgraded version of HTML4, compared to the latter, HTML5 increased the performance of Web pages, but also increased the form, local data and other new functions, the construction of our website is a new experience, but also an opportunity, Because of the many features of HTML5 innovation and Reform for our future website construction is a good guide.

A new <canvas> mark appeared in the HTML5

Flash you all know, this is a let everyone very headache things, some webmaster in order to make their own picture more gorgeous dynamic, so on the home page loaded with a variety of flash video, so that, although the effect of Web pages has been improved, but the speed of the website to go down. Because when the visitor opens a website, these bloated flash video will load, only after loading completes can present, if your host is sharing, then your website loading speed will be quite sad urge.

But HTML5 is not the same, it produces a new <canvas> tag, it can not only provide flash-related features, but also can make the site video loading speed drop, which makes the site does not need to access speed to reduce the use of video.

Two HTML5 new <header> and <footer> signs

Web site structure is the basis of spider crawling, the site only has a clear level to further improve the spider's crawling effect and crawl rate, but before the HTML4 Css+div program, although the site directory, navigation and other columns set clearly clear, But it does not give spiders the fastest way to reach every corner of the site, and HTML5 changed these, it's designed to better cater to the site's anatomical structure, located on the page of the spider is like in the center, any corner is the same distance, which increased the spider's "Access depth", Conducive to the overall weight of the site to improve.

Third, audio and video embedded functions appear

HTML5 is universally praised, the key lies in its user experience breakthrough, compared to html4,html5 new <audio> and <video> tags, it can be audio and video perfectly embedded in the Web page, without affecting the load speed of the site , compared to what I said earlier <canvas> mark,<audio> and <video> tags more humane, can let the user experience the new page feeling.

But which of the <audio> and <video> tags and <canvas> tags is good? This is not comparable, one is to replace Flash, a user experience to improve, these two things are clearly not a concept of things.

Four more convenient management

The author mentioned earlier that HTML5 has added local data to this new feature, which will embed a local SQL database to speed up interactive search, caching, and indexing functions. Also, those offline Web programs will benefit, in addition, because HTML5 added a new form, so that when we build the site for the URL can use micro-data, this way of change, can let us cleaner management of the Web page, so that the overall level of the entire site is clear, for search engines is quite good.

Of course, the above is not HTML5 all the advantages, I just listed a few for our station more favorable aspects, but HTML5 now function is not perfect, although some browsers already support some of HTML5 functions, but if your site using HTML5, it will constantly update the code, This is a great test of your time and energy, so it's better to HTML5 when it's fully mature.
