一次级联几个班级 [英] Cascading several classes at once
问题描述
我尝试组合几个类的属性。这是通过将一个
空格分隔的类定义列表分配给一个元素来完成的。但是，在选择合适的房产时，IE显示了一种优惠价格，我认为这可能是错误的。这就是它的作用：
如果在提供相同属性的样式表中定义了两个类，并且如果将这两个类分配给一个类，则为
单个元素，使用类'的属性的首选项是* * *由元素类定义
设置，而是由样式表中的类定义序列设置。
我认为这会带来很大的灵活性。任何意见？
这是一个例子：
---------------- -
..c1
{颜色：黑色;
}
..c2
{color：red;
}
-----------------
< span class =" c1 c2">这显示为红色。< / span>
< span class =" c2 c1">这也显示红色。< / span>
-----------------
我的意见应该是：
-----------------
< span class =" c1 c2">这显示为红色。< / span>
< span class =" c2 c1">这显示为黑色。< / span>
---------- -------
I try to combine properties of several classes. This is done by assigning a
space separated list of class definitions to an element. However, IE shows a
kind of preference when choosing the right property which I think is
probably wrong. Here''s what it does:
If two classes are defined in a stylesheet providing the same property, and
if these two classes are assigned to one single element, the preference
which class''s property is used is *not* set by the elements class definition
but by the sequence of class definitions in the stylesheet.
I think this takes away much flexibility. Any opinion?
Here''s an example:
-----------------
..c1
{color: black;
}
..c2
{color: red;
}
-----------------
<span class="c1 c2">This is shown red.</span>
<span class="c2 c1">This is also shown red.</span>
-----------------
To my opionion it should be:
-----------------
<span class="c1 c2">This is shown red.</span>
<span class="c2 c1">This is shown black.</span>

这是正确的行为。
查看
http://www.w3.org/TR/CSS2/cascade.html#specificity
和
http://www.w3.org/TR/html401 /struct/...tml#adef-class
没有什么可以暗示为
单指定的多个类元素除了具有相同的特异性之外还有因此
标准CSS特异性规则适用，样式表确定
适用。

That''s correct behaviour.
Check out
http://www.w3.org/TR/CSS2/cascade.html#specificity
and
http://www.w3.org/TR/html401/struct/...tml#adef-class
There''s nothing there to imply that multiple classes specified for a
single element have anything other than equal specificity. Thus the
standard CSS specificity rules apply and the stylesheet determines
which applies.

你认为向CSS小组提出这样的行为是否值得？

Do you think it might be worth proposing such behaviour to the CSS group?
