Question

我的代码在这里：http://jsfiddle.net/u9BsD/2/

您将看到第二部分#indoorRange正在应用最后一个子项，将最后一个框向右推，并将宽度增加1％。 #membership的第一部分是完全相同的，但是有三个块但是last-child类没有影响它应该的元素。是否有一些关于我不知道的最后一个孩子规则的规则？

感谢您的帮助。

Answer 1

从HTML中移除<div class="cl"></div>并将#indoorRange { clear: both; }添加到css中，我相信这会修复它。

样式未应用于最后一个成员资格greyHeading，因为<div class="cl">元素实际上并不是最后一个成员。

编辑：fiddle for proof

EDIT2：我对应用了样式的cl div是正确的，你也许可以使用last-of-type伪选择器来实现你想要的东西，不幸的是我不知道什么是浏览器支持。

Answer 2

这不是最理想的答案，因为它无法解决原因：最后一个孩子不能正常工作。但是，这对我有用，可能是一个合适的解决方案。

我所做的只是从使用最后一个孩子切换到n-child。所以这两个特定的类是变化...我还添加了背景颜色，使它更明显地表现在它们在这里的jsfiddle中工作：http://jsfiddle.net/u9BsD/3/

#memberships .greyHeading:nth-child(3) {
    float: right;
    margin: 0;
    width: 33%;
    background: red;
}

#indoorRange .greyHeading:nth-child(4) {
    float: right;
    margin: 0;
    width: 25%;
    background: blue;
}
