一、在样式表开头添加一个注释块,用以描述这个样式表的创建日期、创建者、标记等备注信息。
Example Source Code:
/*
---------------------------------
Site: Site name
Author: 52CSS.com
Updated: Date and time
Updated by: Name
---------------------------------
*/
二、包括公用颜色标记
Example Source Code:
/*
---------------------------------
COLORS
Body background: #def455
Container background: #fff
Main Text: #333
Links: #00600f
Visited links: #098761
Hover links: #aaf433
H1, H2, H3: #960
H4, H5, H6: #000
---------------------------------
*/
三、给ID和Class进行有意义的命名
不推荐的命名方式:
Example Source Code:
.green-box { ... }
#big-text { ... }
推荐使用的命名方式:
Example Source Code:
.pullquote {... }
#introduction {... }
四、将关联的样式规则进行整合
Example Source Code:
#header { ... }
#header h1 { ... }
#header h1 img { ... }
#header form { ... }
#header a#skip { ... }
#navigation { ... }
#navigation ul { ... }
#navigation ul li { ... }
#navigation ul li a { ... }
#navigation ul li a:hover { ... }
#content { ... }
#content h2 { ... }
#content p { ... }
#content ul { ... }
#content ul li { ... }
五、给样式添加清晰的注释
Example Source Code:
/*
---------------------------------
header styles
---------------------------------
*/
#header { ... }
#header h1 { ... }
#header h1 img { ... }
#header form { ... }
/*
---------------------------------
navigation styles
---------------------------------
*/
#navigation { ... }
复制代码
