The difference between html and html5

With the popularity and development of the Internet, Html (Hypertext Markup Language) has gradually been continuously upgraded and improved from version 1.0, version 2.0, version 3.2, version 4.01 to version 5. Among them, the latest version of Html5 has gradually become the new favorite in the online world. So, what are the differences between Html and Html5? Let’s explore it together.

First of all, the syntax of Html5 is more rigorous than the old version of Html. Html5 has strict grammar standards and respects standards more. It cancels some strange tags and attributes in the old version of Html, such as font tags, center tags, etc., and pays more attention to the semantics and structure of tags. At the same time, Html5 also adds new syntax elements, such as section, article, nav, header, footer, etc. These new elements can better describe the structure of the page and enhance the readability and maintainability of the page.

Secondly, Html5 has stronger support for multimedia and graphics processing. Html5 provides web developers with more standard APIs for processing video, audio, painting and animation. Through these APIs, multimedia content can be embedded in web pages. For example, you can use the HTML5 video tag to embed video files, and the audio tag to embed audio files, etc. Html5 also provides Canvas API, which allows more flexible drawing of 2D and 3D graphics in web pages.

Once again, Html5 can better support the development of mobile devices. Html5 provides more support for mobile devices, such as allowing developers to generate specialized Touch events on mobile devices, as well as more intelligent canvases and styles, so that web programs on mobile devices can be better developed.

In addition, Html5 can better support the development of offline web applications. By using Html5's offline application cache, web applications can be stored locally in the repository without needing to be connected to the Internet, making offline applications more common.

To sum up, Html5 not only retains the basic functions of Html, but also makes many improvements and extensions in aspects such as graphics and media processing, mobile devices and offline web applications. At the same time, Html5 is also more compliant with standards and pays more attention to semantics and structure, making web pages accessible faster, with stronger functions and better compatibility.

Of course, Html5 is not perfect. It also has some flaws, such as browser compatibility, some new technologies that are not mature enough, etc. However, with the continuous advancement of technology and the continuous improvement of Html5 technology, we believe that Html5 will become the main standard for future web development.
