This article brings you a detailed explanation of CSS writing specifications. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.

1. Writing order

Write in order according to the importance of the attributes

Just follow the horizontal order, first display the positioning layout class attributes, and then the box model and other own attributes , and finally the text class and modification class attributes.

##list-styleoverflowcolor1.
→→→ Display properties Self properties Text properties and other modifications
display width font
visibility height text-align
position margin text-decoration
float padding vertical-align
clear border white-space
##top min-width background
Position attribute

(position, top, right, z-index, display, float等)
2.

Size

(width, height, padding, margin)
3.

Text series

(font, line-height, letter-spacing, color- text-align等)  
4.

Background

(background, border等)
5.

Others

(animation, transition等)

2. Selector level

a = 行内样式style。
b = ID选择器的数量。
c = 类、伪类和属性选择器的数量。
d = 类型选择器和伪元素选择器的数量。

Selectorstyle=””wrapper #content {}#content .dateposted {}##p# content {}0,1,0,1#content p {}0,1,0,1#content {}0,1,0,0 0,0,2,10,0,1,2## .comment p {}0,0,1,1
Level (a,b,c,d)
1,0,0,0
0, 2,0,0
0,1,1,0
##p.comment .dateposted {}
p.comment p {}
##p.comment {} 0,0,1,1
.comment {} 0,0,1,0
p p {} 0, 0,0,2
p {} 0,0,0,1
##3、 Writing standards, abbreviation attributes Attribute abbreviation

Remove the 0 before the decimal point

Abbreviation naming , but the premise is that people can understand your abbreviation

Hexadecimal color code abbreviation

hyphen CSS selector naming convention

1.长名称或词组可以使用中横线来为选择器命名。

2.不建议使用“_”下划线来命名CSS选择器,为什么呢?

输入的时候少按一个shift键;

浏览器兼容问题 (比如使用*tips的选择器命名,在IE6是无效的)

能良好区分JavaScript变量命名(JS变量命名是用“*”)

Don’t use id easily

id is unique in JS and cannot be used multiple times, but using class selector It can be used repeatedly. In addition, the priority of id takes precedence over class, so id should be used as needed and not abused.

Add status prefix to selector

Sometimes you can add a prefix indicating status to the selector to make the semantics clearer. For example, the following figure is to add The ".is-" prefix is ​​added.

image
