in the the early 1990s, HTML was published as a simple markup language for displaying hypertext on the Internet. After the development, the HTML gradually contains the picture and the layout design function. To support interactivity, it adds JavaScript. Gradually being contacted by netizens, good page color and some layout experience are important factors to attract netizens to visit the page, in order to meet the requirements of page designers, HTML adds a lot of display function. But as these features grow, HTML becomes more cluttered and HTML pages become bloated. So CSS was born, because of the introduction of the stack style sheet (CSS) so that data and design can be separated, so div+css of the front-end page development model appears, to color and pictures to the original page elements of the construction and beautification, with page elements of the page data layout and classification. Because of the rapid development of the front-end pages, the development of HTML and CSS applications began to develop quickly, and finally, the advent of APIs and core code to enable HTML access to more complex software features-support for more advanced interaction and cloud services integration. This is today's HTML5: It's a collection of technologies that set HTML, JavaScript, CSS, and APIs together.

HTML is a continuous development and innovation story. Through open, flexible collaborative innovation, HTML has been supporting the ever-changing needs of the Internet. The invention of the browser manufacturer, technician, and developer inspires the infinite possibility of HTML ... The standard regulatory Body (the consortium) has been pushing the industry to agree on what HTML should contain, and to encourage compatibility. This allows HTML to be parallel to the browser. Now the introduction of HTML5 enables HTML and browser technology to meet the needs of developers to adapt to a variety of devices. Today many browsers are based on open source code development, most mobile browsers are based on open source project WebKit development. Modern browsers actually have a few large components. Some browser vendors use Open-source code in their browser engine, and then innovate on their own, creating proprietary components such as their user interface. Google uses WebKit in its Chrome browser engine to run HTML5 based applications on Android phones and tablets. So is Apple's Safari and iOS. Most mobile platforms are the same. The browser engine is large for running a particular application like this, which we call the Web runtime. These HTML5-based runtime developers offer great convenience. HTML5 enables developers to develop robust applications more easily and faster. And because Web browsers and mobile Web runtimes are based on the same code, developers can now cost-effectively develop applications for a variety of devices. Really cool, everything just starts with a simple angle bracket. --------------------the point------------------------- ~~~~~~~~~~ Front-End PK back-end ~~~~~~~~~~~~ ------------------KO and OK---------------------- ~ If you're the front end then ask 1, what is the reason for you to choose the front end. 2, will also write compatible code to IE678.
