html html5 is different

HTML and HTML5 are two different versions, both of which are very important in web development. HTML is the abbreviation of Hyper Text Markup Language, which is a markup language used to create static web pages. HTML5 is the latest version of HTML. It is a new technical standard that introduces some new elements and functions to make web development more advanced and efficient.

First of all, there are some functional differences between HTML5 and HTML. Some new elements and APIs have been added to HTML5 with stronger support, such as audio, video, canvas elements, geolocation API, etc. These elements and APIs make web development more flexible and creative, increasing the multimedia interactivity and user experience of web pages.

Secondly, HTML5 has some upgrades and changes in syntax compared to HTML. HTML5 has simpler code, fewer tags and attributes, etc., making the code more readable and understandable. At the same time, HTML5 also introduces new semantic tags, such as

,

,

,

, etc., which are slightly similar to XML extension tags, much smaller, and lack of features. Added sections; these tags make the page structure clearer and helpful for search engine optimization (SEO).

Finally, there are some differences in browser compatibility between HTML5 and HTML. Because HTML5 is a more comprehensive and complex standard than HTML, some older browsers may not support some new elements and APIs in HTML5. This requires the use of proper compatibility techniques in web development so that web pages can display and run normally on different browsers.

In short, HTML5 is an upgraded version of HTML, which adds some new elements and functions, and has been upgraded and changed in terms of syntax. It makes web development more flexible, innovative, and has better user experience and search engine optimization (SEO). However, due to browser compatibility issues, web developers need to pay attention to using the correct techniques and tools during the development process to ensure the compatibility and stability of web pages.
