Question

为什么overflow:auto; .pageContent打破了Chrome和Firefox中的布局？它在Safari中运行良好。我该怎么办呢？我添加了它，因此clear:both;上的h2只会清除内容，而不会清除整个.pageAttributes div。

Here是网站。

它似乎是导致它的菜单中的border-bottom .selected。但仍然不确定为什么。

更新 - 测试用例jsfiddle

我已尝试overflow: visible;，但这会打破h2。

        <div class="button selected">Edit</div>

Answer 1

试试这个，

#articleSections{
    float: left;
}

并从overflow: auto;

中删除.pageContent

Answer 2

对我来说，似乎是一个浮动的问题，我无法在.button（s）和搜索输入之间清楚。所以定位可能是这样的解决方案
