Web front-end development engineers need to master what are the core skills, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain in detail for you, people with this need can come to learn, I hope you can gain something.

The content of Web front-end development mainly includes the structure, behavior and performance of W3C standards, 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, and after many updates, the emergence of HTML5 and CSS3 is another innovation. Some people think that the skills that front-end developers need to master are simple, that is, making web pages. In fact, xHTML+CSS+JavaScript,JavaScript, the core language that web front-ends need to master, is one of the most difficult languages, and many programmers dare not belittle themselves and claim to be proficient. Due to the difference between JavaScript and html, as well as some benefits of static and dynamic separation. Writing static and dynamic effects in large companies is often done separately by different people. Because of the need to reduce costs, small companies require everyone to know as much as possible. if you want to develop as a project manager and understand one or two background languages, it is definitely the icing on the cake!

two。 Browser compatibility

At present, the mainstream browsers of the Internet are IE6\ 7\ 8\ 9, Firefox, ChromePhone, Opera, Safari, roaming, including domestic mainstream Sogou, Tencent TT,360,the World and so on. From the kernel, there are mainly IE, roaming version of IE,safari,firefox and opera, these are common, if there is an old web worm around you who likes to collect browsers, if you flip through his hard drive, I believe there must be dozens of them (or check the browser collection in the front-end community http://www.w3cfuns.com). The parsing of code in each kernel is not exactly the same, and even the same kernel may vary greatly, such as IE and the roaming version of IE. Not to mention non-mainstream browsers, it is not easy for mainstream browsers to be fully compatible, which requires a long time of accumulation and testing, and requires front-end development engineers' love and passion for front-end development.

At present, the development trend of the mobile Internet should not be underestimated, and it will gradually occupy the main share of the Internet. The most prominent advantage of the mobile Internet is convenient and timely. Just imagine, walking in a certain place has a good scenery, and after being photographed, it is automatically shared with all kinds of friends, so it is urgent to see the compatibility of browsers on mobile phones. Now browsers on mobile phones are also numerous and complicated, with mainstream UCWEB,safari,IE,3G portals and "crippled children" of symbian low-end phones, including some browsers that we do not know about popular mobile phones abroad. To make matters worse, each browser gets a completely different result because of the different hardware of the phone.

3.hack technology

Because different browsers have different understanding of CSS parsing, it will lead to different page effects. 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 in accordance with the standard, not hack code, but in order to be compatible with mainstream browsers, hack code is inevitable, so this should also be a necessary skill for every front-end developer.

4. Industry standard

At present, W3C standard is most mentioned in Web front-end development, which is a collection of a series of standards, representing the direction of the development of the Internet, but also represents a belief in front-end development. All the code written must pass 100% of the standard verification, and be proud to pass the standard verification, which will effectively promote the rapid development of the Internet.

5. Development tools

At present, the more popular is Dreamweaver, which was once popular for a time, but now it has not withdrawn from the historical stage, which proves that DW still has great advantages, especially for beginners, its powerful prompt function can help us quickly familiarize ourselves with and master the page layout, but now we are more advocating pure handwritten code, which not only reflects the excellence of skills, but also effectively avoids redundant code generated by tools such as DW. In addition, if you master some photoshop skills, you can easily process some images even if you don't have artists.

Summary, with 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 on your own. Although this looks similar to web design, in terms of effect, it is to make web pages, but in fact, the technology has gone beyond several levels of things.
