Basic knowledge and skills to be mastered by web front-end engineers

At present, the Web product interaction is more and more complex, user experience and site front-end performance optimization These all rely on the Web front-end engineers to do, web front-end engineers are design and development of the complex, web front-end engineers are the most direct-oriented products in the developer, user-oriented designers, The result of a development team is to rely on the Web front-end engineers to show, because the user does not care about the background of how strong the processing, in the designer of the Web front-end engineers are directly oriented to the developers of the designer, to the developers in a computer language to pass their design ideas, Web front-end engineers are critical throughout the team.
The basic knowledge and skills to be mastered by web front-end engineers include:
1, the basic structure of the Web page (HTML + CSS)
HTML is a markup language, not a programming language, the most basic is the tag is and, CSS is used to define how to display HTML elements. It's easy to get started with html+css, but a lot of people aren't deep enough to give a few examples:
What's the use of the sign? What is the difference between margin-left and left, and under what circumstances should it be used? And then a div+css layout problem: A div with a width of three horizontal aligned div inside, two div width fixed to 150px, The Middle Div fills the remaining width. If you do not know these problems at the moment, the layout of the problem within a few minutes can not be resolved, indicating that you are not enough in-depth html+css.

2, the browser is how to show the Web page
Different kernel browser to the page rendering is not the same, the browser now has a client debugging tool, showing a Google home page under the IE9 loading details:
Learn more about browser rendering and details when doing Web performance optimization. Say a more useful point of knowledge: the current browser parallel loading limit is 6, the old version of the browser will be different.
3, the life cycle of the Web page
Depending on the web framework, the life cycle of the page will be different, roughly the same: the client sends a GET request, the server returns to the corresponding page, the client completes the operation and data, and then posts it to the server. Be sure to keep the details of the data passing (front and back, between pages) in mind.

4, server-side language development experience, PS cutting technology
Web front-end development is somewhere in the middle of design and development, so everything on both sides has to be understood. Editing language is interlinked, previously written server language, for learning JavaScript is very useful, from the picture to static HTML page, without the PS cut graphics technology.

5. Browser compatibility
For historical reasons, browser compatibility has always plagued the Web front-end engineers, although there are W3 organizations, and developed some specifications, although the browser manufacturers are trying to improve and close to their specifications, but the real network environment of various kernels, various versions of the browser has a place. Solve browser compatibility by accumulating experience.

6. Rapid learning ability and active learning willingness
The development of the Web front-end quickly, engaged in this industry must have rapid learning ability and active learning will, so as to adapt to the requirements of web products. In the Web front-end domain there is no absolute and non, solve a problem in a number of ways, but we have to find a more appropriate method, to find a more appropriate method needs to accumulate experience, in short, the Web front-end easy to get started, want to proficiency difficult, need more active learning will.
7. Good communication skills
Excellent front-end engineers need to have good communication skills, because your work is closely related to many people's work, such as project managers, designers, end users, development engineers, front-end engineers at the intersection of these categories of people, these roles require you to take care of, balance the needs of these four categories of people, Come up with a more appropriate solution. This shows that the communication ability to the front-end engineers demanding higher.
The future of the web and today will be a big difference, and your job is to figure out how to use their own web application to reflect this tremendous change, since stepping on the Web front-end development road, it is strong to go down!
