尝试规范css代码

1.模块分割，用如下的标注来提示你的css代码作用；
    /* -------------*/ /* ---------->>> GLOBAL <<<-----------*/ /* ----------*/

A sample format I try to stick to is this:

Global Styles – (body, paragraphs, lists, etc)
    Header
    Page Structure
    Headings
    Text Styles
    Navigation
    Forms
    Comments
    Extras

2.代码的统一管理

例如：
        1）.标题
                h2 { }

#snapshot_box h2 {
                        padding: 0 0 6px 0; }

#main_box h2 {
                        color: #e2e2e2; }

.sidetagselection h2 {
                        color: #fff;
                        font: bold 14px/14px “Verdana”, sans-serif; }
                        
     you’ll be able to style each one independently and not worry about child classes inheriting attributes from the parent class.
        
3.使用简写
        例如：margin: 0px 1px 0 0;
4.头部样式的使用的重要性；important；
    If you know that all of the h2’s will not have a margin or padding, define that on the top level and let its effect cascade as it is supposed to.
