Ask a question about css under ie6! _html/css_WEB-ITnose

I would like to ask:

#name_a{.....;}li{....;}

Is this not possible? ?
Should they be separated:

#name_a{....;}#name_a li{.....;}

Reply to discussion (solution)

Isn’t the first one written separately? Well. . Just no line breaks. . What has changed is everything. . .

#name_a li{
and
li{
The range of selection is different

Both are ok, personal preference, you can use the entire css file without A branch is enough. Look at Jingdong’s css, which is densely packed. There are no branches.

.main{...}.menu{....}.top{...}
As above Writing will make the css file take up less space, but it will be difficult to read

.main{...}
.menu{....}
.top{...}
The css file written like this will be a little larger, but more organized
