what html5 does

With the popularity of the Internet and mobile devices, HTML5 has become the focus of web design and development. So, what can HTML5 do? This article will introduce you to the main features and functions of HTML5 in detail.

1. Multimedia processing

HTML5 can handle audio and video files, eliminating the need to use plug-ins such as Flash. The playback of video and audio requires the use of HTML5 video and audio tags. These tags can easily control the playback, pause, volume and other settings of audio and video. In addition, HTML5 also adds some new image tags, such as canvas and svg, allowing developers to process images more flexibly.

2. Local Storage

HTML5 provides the local storage function, making accessing local files more convenient. Developers can use HTML5's localStorage or sessionStorage objects to store data in the user's local browser. Therefore, when the user disconnects from the network, the user can still access the data from local storage.

3. Support Responsive Design

Responsive design refers to the design and development of web pages that work across all device types, screen sizes, and resolutions. HTML5 provides media queries, flexboxes, fluid layouts, and other features that allow web pages to automatically adapt to all screens.

4. Progressive enhancement function

HTML5 has many new features, but old browsers that do not support HTML5 cannot use these features. To solve this problem, HTML5 supports progressive enhancement. This means developers can write basic functionality for existing browsers without having to consider HTML5's advanced features. When users use advanced browsers, web pages will automatically enable these advanced features.

5. Web Application

HTML5 can use some new tags and features to develop web applications. HTML5 supports Web application offline storage, Web Worker, Web Socket and other functions, which can enhance the performance and interactivity of Web applications.

In short, HTML5 has many powerful features, including multimedia processing, local storage, support for responsive design, progressive enhancement and web applications, etc. As a web designer and developer, understanding the capabilities of HTML5 allows you to develop high-quality web pages and promote an improved user experience.
