Today, the editor will share with you the relevant knowledge of what the seven advantages of html5 are. The content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article. Let's take a look at it.

Html5 is free and open, without plug-ins, faster, more efficient, search engine friendly, better security, cross-platform, low development cost and simple development. And HTML5 has a more powerful video function; supports video recording; allows Web pages to run applications; supports rich 2D images; supports instant messaging.

The operating environment of this tutorial: windows7 system, HTML5 version, Dell G3 computer.

Flash was born in the 1990s and was developed by a stroke software company called FutureWave. At first, Flash was just an animation assistant software. Flash pictures and animations are based on vector storage, and vector graphics can be generated through CPU, and zoom in and out without distortion, so you only need dozens of KB to hundreds of KB, you can easily achieve a few MB pictures that others need. In the early 1990s, the speed of the Internet was still calculated by Kb, so Flash, which supports the compact vector format, became the most suitable animation software at that time.

Flash is suitable for low-speed Internet content, and it is also very attractive in the fields of games and animation. Mini Game such as 4399 Mini Game and "Sail" have sprung up one after another, and you can open and play directly on the web page. Ten years ago or even five years ago, Flash games represented by 4399 Mini Game brought countless happy times to teenagers. In animation, the production of Flash animation is simple, and small animations such as loving kids, spoofed mung bean frogs and cured Ali have spread widely on the Internet, and there are still many old net names to remember these classic animation images.

H5 replaces Flash

At its best, Flash even had a separate user base-Flash. Flash word is Flash, flash refers to the use of Flash to create a variety of animation groups. Now that times have changed, many people no longer use Flash, and flash passengers are once dispersed in the dust of history. Open video websites, mostly switch to H5 technology, once represented the advanced trend of Flash, but was abandoned by the major video sites.

Some people may not understand why Flash was abandoned. This has to mention one person, Jobs. The Apple founder is the first celebrity to take the initiative to criticize Flash. In Jobs' view, Flash has three main shortcomings: "the first Flash consumes a lot of power, the second it runs slowly, and the third it has security problems."

As a product of the PC era, Flash directly uses CPU resources, which naturally brings huge energy consumption. Apple mainly uses mobile touch screen phones, which have strict requirements for battery life, and the Flash is obviously not suitable. In addition, after more than ten years of development, Flash has too many functions and low efficiency. The later Flash, which can decode H.264, do 3D rendering, play 7.1-channel surround sound, and support game consoles, is powerful but too bloated.

Jobs prefers H5 technology to Flash. H5 has the technology to do almost everything Flash can do, with free open, plug-in-free, faster, search engine-friendly and other advantages, completely killed Flash. H5 is more efficient and secure, and there is no need to install plug-ins, and H5 will soon replace Flash in video, animation, and even advertising.

7 advantages of html5 over Flash:

1. Video playback is supported.

One of the reasons why Flash is popular is that it can play videos. HTML5 has a more powerful video function, which can control pause, playback and start at any time. Its powerful functional system is completely comparable to YouTube and other Flash sites.

2. Support video recording function

Today, this feature is not popular. According to Beccue, this feature will become increasingly important. Because at present, all mobile virtual devices that provide Web access interface have camera function.

3. Support audio playback / recording function

At present, you may need to use Flash, Quicktime or Java to play / record audio, which is one of the features of HTML5.

4. Application program

HTML5 allows Web pages to run applications, just like normal applications. (download Financial Times app to experience this feature)

5. Support rich 2D images

HTML5 embeds all complex two-dimensional picture types. It runs much faster than the way the website loads pictures at present.

6. Support instant messaging

The Web sockets-based instant messaging function is built into HTML5, and once this function is enabled between two users, you can maintain smooth communication.

7. Real-time stream

WebSockets will allow any Web page designer to easily add real-time data streams (from stock market prices to online reports) that require more complex programming skills than HTML programmers.
