tjf*_*ker 2 css css-selectors css-specificity
我正在使用FirefoxDeveloperEdition并遇到意外的选择器优先级.我已经阅读了Smashing Magazine的文章"CSS特异性:你应该知道的事情",并且,据我所知,已经构建了CSS选择器,因为它们应该是为了达到每个特定的预期水平.但是,错误的声明正在被取消.
这是什么问题?我是不是完全围绕选择器特异性的运作?这是一个错误吗?或者是其他东西?

试过.hud > .main > .buttonvs.hud > .main p

也试过.hud > .main > .buttonvs.hud > .main p:not(.botton)

这是因为第一个样式匹配元素,第二个样式从它的父元素继承.
当两个选择器匹配相同的元素时,特异性仅起作用.不是从父元素继承样式.
你可以看到这个非常简单的例子:
#myID {
color: red;
}
p {
color: green;

<div id="myId">
<p>Some text</p>
</div>Run Code Online (Sandbox Code Playgroud)
即使#myId更具体的文本是绿色的,因为p选择器直接匹配该元素,因此比color继承更重要div.
要p在.button白色内部制作元素,您需要:
.hud > .main > .button p {
color: #fff;
}
