How to make Css--better (Series II)

The previous article (How to make Css--beter series one) analyzes what kind of code is efficient and what kind of code should be avoided, so what kind of code is easier to extend? What code is better to maintain? What code is better?

Let's just talk about the efficient code. If the style of the input type on the registration and login page is the same now, what should I do? Registered outer container for REG login The outer container is login so trust me.

. Input-user { This is a property } General and registration and login  or. log. Input-user{ This is the property }. reg. input-user{ This is the property }

We prefer the generic code (because it's the same), why write it two times?

This is a better code.

So if the code is better maintained, please come out three mysterious guest (semantic css, and annotations, the last powerful modular CSS).

A brief introduction (1) semantics is what you write CSS to see what is written if you have a lot of code to write is AAA BBB CCC or CSDB and so on, you will feel upset. Suggest direct English alphabet to write

Like what

Input-user He's talking about the input tag that fills in the user's name.

Input-password that is to fill in the user name password that input tag and so think a bit long can take the abbreviation but to let others can see you write this thing is what things can not be abbreviated to I-P at least also want to input-pwd kind of

How about thousands of lines? It is recommended to write a note indicating that the following code is placed there in this case we implemented the module in the CSS file if you want to rebuild the sidebar later I can directly delete your code or rewrite it, there is no need to continue to find a page to write code (maybe there is a style conflict)

The Last is (3) modular modularity is simply to put your CSS into modules to deal with, for example, your reset.css may not change in ten years, so just put it in a new folder to save your page CSS as for the modular CSS I don't have to say the time is limited we can straight Baidu Modular CSS selection to fit their own modular structure

This is the younger brother's modularity may be some simple because this project is very small can not give more pictures .... Hey...
