CSS使用:不是带CLASS的ID

我相信你正在扭转选择者.您有一些相同的元素class,但您想过滤掉具有特定元素的元素ID.在这种情况下:

HTML:

<p class="someclass">hello</p> <!-- will be targeted by css below, thus green -->
<p class="someclass" id="some-id">hi</p> <!-- will not be targeted by css below -->

CSS:

.someclass:not(#some-id){ color: green; } 
/* selects all elements with classname 'someclass', 
   but excludes the one that has also has an id of 'some-id' */

正如@secretSquirrel指出的那样,请注意浏览器兼容性:Internet Explorer 8及更早版本不支持此选择器.
