In this issue, the editor will bring you about what functions and advantages have been added to HTML5. The article is rich in content and analyzes and describes it from a professional point of view. I hope you can get something after reading this article.

From HTML4.0 to XHTML to HTML5, in a sense, this is a more standardized process of HTML descriptive markup language. As a result, HTML5 has not had much impact on developers. But HTML5 has added a lot of new features and features that are very useful. Here are some of the advantages of HTML5.

1. Solved the cross-browser problem

Before HTML5, major browser manufacturers added a variety of functions to their browsers in order to compete for market share, and did not have a unified standard. Using different browsers, you often see different page effects. In HTML5, all reasonable extension functions are included, and it has good cross-platform performance. For older IE browsers that don't support new tags, you can use new elements by simply adding JavaScript code. It is recommended to understand the dark horse programmer web front-end course.

2. Several new features have been added.

HTML language has undergone great changes from 1.0 to 5.0. from a single text display function to a multimedia display function with pictures and texts, many features have been improved for many years and have developed into a very important markup language. The new features of HTML5 are as follows.

● new special content elements, such as header, nav, section, article, footer.

● new form controls, such as calendar, date, time, email, url, search.

● the canvas element used for painting.

● video and audio elements for media playback.

● has better support for local offline storage.

API such as ● geographic location, drag, camera, etc.

The formulation of HTML5 standards is based on the principle of "user first". In case of conflicts that cannot be resolved, the specification will put users first. In addition, in order to enhance the experience of using HTML5, the following two aspects of the design have been strengthened.

Design of ● Security Mechanism

In order to ensure the security of HTML5, a lot of security designs have been done when designing HTML5. HTML5 introduces a new open source-based security model that is not only easy to use, but also common to different API (Application Programming Interface, application programming interface). Using this security model, you can have secure conversations across domains without the help of any insecure hack.

Separation of ● presentation and content

The separation of presentation and content is another important part of HTML5 design. In fact, the separation of presentation and content has been designed for a long time in HTML4.0, but the separation is not complete. In order to avoid the problems of poor accessibility, high code complexity, and large files, the HTML5 specification separates the performance from the content more carefully and clearly. However, considering the compatibility of HTML5, some old performance and content code can still be used.

4. The advantage of turning complexity into simplicity

As a popular universal markup language, HTML5 is as simple as possible and strictly follows the principle of "simplicity first", which is mainly reflected in these aspects:

● 's new simplified character set declaration

● 's new simplified DOCTYPE

● simple and powerful HTML5 API

● replaces complex JavaScript code with native browser capabilities. In order to achieve these simplified operations, the HTML5 specification needs to be more detailed and precise than before. In order to avoid misunderstanding, HTML5 has a very clear specification for every detail and does not allow any ambiguity or ambiguity.

These are the functions and advantages of the HTML5 shared by the editor. If you happen to have similar doubts, you might as well refer to the above analysis to understand. If you want to know more about it, you are welcome to follow the industry information channel.
