Core skills that web front-end development engineers need to master

The content involved in Web front-end development mainly includes the structure, behavior and performance in the W3C standard. So what are the core skills we need to master in these three items?

1. Development Language

HTML has a history of more than 20 years of development and has undergone many version updates. The emergence of HTML5 and CSS3 is another innovation. Some people think that the skills required for front-end development are simple, isn't it just making web pages? In fact, it is not. The core languages ​​that need to be mastered in the web front end are xHTML+CSS+JavaScript. JavaScript is one of the most difficult languages, and many programming experts do not dare to belittle themselves and claim to be proficient in it. Due to the differences between JavaScript and HTML, as well as some benefits of separate processing of static and dynamic. In large companies, the writing of static effects and dynamic effects is often done separately by different people. Because small companies need to cut costs, they require everyone to know as much as possible. If you want to develop into a project manager, knowing one or two backend languages ​​will definitely be icing on the cake!

2. Browser Compatibility

The current mainstream browsers on the Internet are IE6\7\8\9, Firefox, Chrome, Opera, Safari, Maxthon, including the domestic mainstream Sogou, Tencent TT, 360, the World, etc.; in terms of the kernel, there are mainly IE, Maxthon version of IE, safari, firefox and opera, which are all common. If you have an old Internet addict around you who likes to collect browsers, you can look through his hard drive and I believe he must have dozens of them (or check the browser list in the front-end community http://www.w3cfuns.com ). Each kernel parses the code differently. Even the same kernel may have big differences, such as IE and the Maxthon version of IE. Not to mention non-mainstream browsers, even achieving full compatibility with mainstream browsers is not an easy task. It requires a long period of accumulation and testing, as well as the love and passion of front-end development engineers.

The current development trend of mobile Internet cannot be underestimated and will gradually occupy the main share of the Internet. The most prominent advantage of mobile Internet is its convenience and timeliness. Imagine that you are walking somewhere and see a beautiful scenery, and you can take a photo and automatically share it with your friends. Therefore, browser compatibility on mobile phones is urgent. Nowadays, browsers on mobile phones are complicated, including the mainstream UCWEB, Safari, IE, 3G portal, and the "incomplete children" of Symbian low-end phones, including some browsers on popular foreign phones that we don't know about. What's worse is that these browsers parse completely different results from each browser due to different mobile phone hardware.

3. Hack technology

Since different browsers have different understandings of CSS parsing, the generated page effects will be different. At this time, you need to write different CSS for different browsers. This process is called CSS hack. Although we are required to write code according to standards and not write hack code, hack code is inevitable in actual work in order to be compatible with mainstream browsers, so this should also be a necessary skill for every front-end developer.

4. Industry Standards

Currently, the most mentioned standard in Web front-end development is the W3C standard, which is a collection of standards that represents the direction of Internet development and also represents a belief in front-end development. All the codes we write must pass 100% standard verification, and we should be proud of passing the standard verification, which will effectively promote the rapid development of the Internet.

5. Development Tools

Currently, Dreamweaver is more popular. It was once all the rage and has not left the stage of history. This proves that DW still has great advantages, especially for beginners. Its powerful prompt function can help us quickly become familiar with and master the layout of web pages. However, pure handwritten code is more recommended now, which not only reflects excellent skills, but also effectively avoids redundant code generated by using tools such as DW. In addition, if you master some Photoshop skills, you can simply process some images even without an artist.

In summary, if you master the above skills, you can be said to be a qualified front-end developer who can participate in a large project or write a web page independently. Although this looks similar to web page design and the effect is similar to web page production, in fact, the technology is several levels higher.
