1.What is HTML5
Generally speaking, HTML5 includes three parts: HTML, CSS and JavaScript. It is not just the first impression of just the HTML part, but also at the CSS 3 and JavaScript levels. Many innovations have made the entire web page more powerful from layout to processing. The newly included technologies have made functions that were previously difficult to implement and full of security risks a reality.
HTML is the abbreviation of HyperText Markup Language. It is an application under the standard universal markup language. It is also a specification and a standard. Use mark symbols to mark the various parts of the web page that you want to display.
From the emergence of the first version to the present, HTML has gone through 5 revisions, from HTML 2.0 to HTML 5. HTML has used its own advantages to prove its advantages in websites, so much so that it has replaced the ancient C language programming to structure part of the website.
2. Why use HTML5
THML5 is more appropriate in layout. Remember the transition from the previous mainstream table to the mainstream div; today’s layout is more friendly to search engines, such as
Article content will always be included, and nav is navigation information; HTML5 mobile phone support is also becoming increasingly complete, and mobile compatibility is a simple concept.
Although multiple networks are integrated into one, compatibility issues will always exist, and layout adaptation is also a technical job; in addition, it also plays an increasingly important advantage in other clients such as Pad.

HTML is used to organize the structure of web pages, just like the human skeleton. The first thing you have to do is learn its syntax and everything related to it. The key points to learn are as follows:

Task - After learning the basics of HTML, please write at least 5 HTML pages. My suggestion is to choose any website page, for example, try writing any Github configuration page or Twitter login page, and make sure the structure is correct.
Although the finished page looks ugly, there is no need to worry yet. The focus at this stage is to learn to write the correct structure.
Currently, the mainstream web browsers Firefox 5, Chrome 12 and Safari 5 already support many HTML5 standards, and the latest version of IE 9 also supports many HTML5 standards.
As users continue to upgrade to new versions of browsers, developers should start developing now, and compatibility issues will become less common over time.
