This article introduces the "how to carry out CSS code to lose weight to improve the front-end performance" related knowledge, in the actual case of the operation process, many people will encounter such a dilemma, then let the editor lead you to learn how to deal with these situations! I hope you can read it carefully and be able to achieve something!

Use the tool

This tool allows us to input our own CSS code and give CSS code to lose weight. So let me give it a try. There is a file to convert. Here is the CSS code.

Nav {height: 40px; width: 100%; background: # 000; border-bottom: 2px solid # fff;} nav ul {padding: 0; margin: 0 auto;} nav li {display: inline; float: left;} nav a {color: # fff; display: inline-block; width: 100px; text-shadow: 1px 1px 0px # 000 } nav li a {border-right: 1px solid # fff; box-sizing:border-box;} nav li:last-child a {border-right: 0;} nav a:hover, nav a:active {background-color: # fff;}

Here are the results.

Nav a:hover, nav a:active {background-color: # fff;} nav {height: 40px; width: 100%; background: # 000; border-bottom: 2px solid # fff; a {color: # fff; display: inline-block; width: 100px; text-shadow: 1px 1px 0px # 000;} ul {padding: 0 Margin: 0 auto;} li:last-child {a {border-right: 0;}} li {display: inline; float: left; a {border-right: 1px solid # fff; box-sizing:border-box;}

As we can see above, our old CSS code has lost a lot of weight, leaving it shorthand, which has the advantage of reducing server-side pressure.

Limitation

However, we can also see some restrictions on the conversion results. In the old CSS, we had several identical code, two declarations about the border border-bottom: 2px solid # fff; and border-right: 1px solid # fff; we just need to manually do other possibilities until the above limitations are resolved. Although there are still limitations, this tool can save us time, and nesting CSS rule sets is very helpful.
