This is very important in website SEO optimization and can help the website rank higher.

In addition, HTML is also very important for website maintenance. For well-structured HTML codes, developers can more easily format and modify pages, thereby improving development efficiency. Additionally, having a clear code structure helps with team collaboration as well as code readability and maintainability.

Finally, in today's digital era, HTML plays an increasingly important role. As more and more people use mobile devices to browse the Internet, HTML is very helpful in building responsive web pages and mobile applications. Web responsive design is the core principle of using HTML and CSS, which allows the website to adaptively layout according to different devices and screen sizes, thereby providing a better user experience.

In short, HTML runs throughout the entire Internet and is an important foundation for building web pages. It provides good accessibility and maintainability for the website, and also provides users with a better experience.
