Front-end development is the process of creating front-end interfaces such as Web pages or app to present to users. Through HTML,CSS and JavaScript and various technologies, frameworks and solutions derived from it, the user interface interaction of Internet products can be realized. It evolved from the making of web pages, and its name has obvious characteristics of the times. In the evolution of the Internet, web page making is the product of the Web1.0 era. In the early days, the main content of the website was static, mainly pictures and text, and the behavior of users using the website was also browsing. With the development of Internet technology and the application of HTML5 and CSS3, modern web pages become more beautiful, more interactive and more powerful.

Core technology of Web front-end development

HTML language

Mastering HTML is the core of web pages, a standard language for making World wide Web pages, and a language used by World wide Web browsers. It removes the obstacles to information exchange between different computers. Therefore, it is the most widely used language on the network, and it is also the main language that constitutes web documents. Learning HTML well is the basic condition for becoming a Web developer.

HTML is a markup language that implements Web pages and displays them in browsers. As the latest version of HTML, HTML5 introduces a number of new technologies, which greatly enhance the ability to support applications, so that Web technology is no longer limited to the presentation of web content.

With the development of CSS, JavaScript, Flash and other technologies, the processing ability of Web for applications has been gradually enhanced, and the experience of users browsing the web has been greatly improved. However, several new technologies in HTML5 have achieved a qualitative breakthrough, so that Web technology is considered to be close to native application technology for the first time, and the development of Web applications has really become a choice for developers.

HTML5 can greatly simplify the work of developers, in theory, a single development can be run on different platforms with the help of browsers, reducing the cost of development, which is generally considered by the industry as one of the main advantages of HTML5 technology. AppMobi, Motorola, Sencha, Appcelerator and other companies have launched more mature development tools to support the development of HTML5 applications.
