具有相同名称的类? [英] Classes with the same name?
问题描述
在同一样式表中使用同名的几个类
有什么问题吗?类似......
div.pagedown {
保证金:20px 0px 20px 0px;
border-top:1px solid #caa;
border-left:1px solid #caa;
宽度:450px;
}
img.pagedown {
保证金:0px 8px 0px 8px;
border-width:0;
}
a.pagedown {
颜色:#903;
}
thx,

Is there anything wrong with having several classes with the same name
in the same style sheet? Something like...
div.pagedown {
margin: 20px 0px 20px 0px;
border-top: 1px solid #caa;
border-left: 1px solid #caa;
width: 450px;
}
img.pagedown {
margin: 0px 8px 0px 8px;
border-width: 0;
}
a.pagedown {
color: #903;
}
thx,

你不可能有多个班级一样的名字。你_can_有多个
样式,选择器匹配同一个类(这就是你所拥有的
以上)。

Thx。我纠正了。而且作为一种风格问题,由于这些都是一起使用的,所以将它们全部称为pagedown是有道理的。
只是想知道其他人是什么做...

Thx. I stand corrected. And as a matter of style, since these are all
used together, it makes sense to me to have them all called "pagedown".
Just wondered what other people do...

你不能拥有多个同名的课程。你_can_有多个
样式,选择器匹配同一个类(这就是你上面的内容)。

You can''t have multiple classes with the same name. You _can_ have multiple
styles with selectors that match the same class (which is what you have
above).
嗯......我想类和选择器是一样的。一个类
如:
..classname {};
是根元素的选择器,不是吗?
此外,我认为你可以将一个类/选择器分成多个
定义,例如:
img.classname {position:absolute};
img.somethingelse {...);
img.classname {background-color:000} ;
Hmm.. I thought that classes and selectors were the same thing. A class
such as:
..classname {};
is a selector on the root element, is it not?
Further, I thought you could break up a class/selector into multiple
definitions, such as:
img.classname {position:absolute};
img.somethingelse {...);
img.classname {background-color:000};
