php - 我模态中的布局未正确显示

Question

我的页面中有这段代码，可以正常工作，但是当出现大模式窗口时，我的页脚出现在上面的内容上。一定是我在代码中看不到的东西，也许有人可以帮助我？

Answer 1

这里可能的原因是 modal-body 没有获得实际高度，因为它的所有内容都是 float 的。您可以在主体的末尾添加一个 clearfix 类。

然后有人可能会说 “但是 form-control 没有 float ”。是的，但是每个 form-control 中的所有内容都使用 col-X，即 float:left。因此，您的 form-control 也没有实际高度。
