Thoughts on HTML5 new functions how to guide future website construction

HTML5 is an upgraded version of HTML4. Compared with the latter, HTML5 adds the expressiveness of Web pages and new functions such as forms and local data, the construction of our website is a brand new experience and an opportunity, because the innovation and reform of all the functions in HTML5 will be a good guide for our future website construction.

　　A new <canvas> tag appears in HTML5.

Flash webmasters all know that this is a headache for everyone. Some webmasters load a variety of Flash videos on the homepage to make their pictures more vivid and dynamic, in this way, although the webpage effect has been improved, the Website access speed will continue. Because when a visitor opens a website, these bloated Flash videos will be loaded and will only be displayed after loading. If your host is shared, then the loading speed of your website will be quite miserable.

But HTML5 is different. It generates a new <canvas> tag, which not only provides Flash-related functions, but also greatly reduces the loading speed of website videos, this makes it unnecessary for websites to reduce video applications for access speed.

　2. HTML5 has a new

The website structure is the foundation for spider crawling. Only a website with a clear level can further improve the crawling effect and crawling rate of spider, however, although the CSS + DIV program, which was previously established in HTML4, makes the directory, navigation, and other columns of the website clear, it cannot provide the spider with the fastest way to reach every corner of the website, HTML5 has changed this. Its design better caters to the anatomical structure of the website. The Spider located on the page is like at the center of the circle, and every corner is the same path, this increases the "Access depth" of the spider and improves the overall weight of the website.

　　3. Audio and Video embedding

The key to HTML5's popularity is its breakthrough in user experience. Compared with HTML4, HTML5 adds the <audio> and <video> tags, it can perfectly embed audio and video into a webpage without affecting the loading speed of the website. Compared with the <canvas> mark I mentioned earlier, the <audio> and <video> tags are more user-friendly, allowing users to experience the new page feeling.

But which of the <audio> and <video> labels and <canvas> labels is better? This is incomparable. One is to replace Flash and the other is to improve the user experience. These two things are obviously not a concept.

　Better Management

I mentioned earlier that HTML5 has added the new feature of local data, which will embed a local SQL database to accelerate interactive search, cache, and indexing. At the same time, those offline Web programs will also benefit a lot. In addition, because HTML5 is added with a new form, we can use micro data for URLs during site building, it allows us to manage webpages more cleanly and clearly define the overall hierarchy of the entire website, which is quite good for search engines.

Of course, the above are not all the advantages of HTML5. I just listed a few aspects that are more advantageous for our website construction. However, HTML5's current functions are not complete. Although some browsers already support some HTML5 functions, however, if your website uses HTML5, the code will be constantly updated, which is a huge test of your time and energy, so it is more appropriate for HTML5 to accept it when it is completely mature.
