html - 框阴影不会出现在等高 div 的底部

Question

我有一个由高度相等的响应框组成的布局。他们有 box-shadow 但底部阴影没有出现。

我认为这是因为 div#latest 的 overflow:hidden 被设置为使框等高，正如 One True Layout Method 中所建议的那样.

HTML代码:

    <div id="latest">
                    <div id="section-header"><h4>NEWS</h4></div>
          <div class="row">
<div id="article-container" class="col-md-3 col-sm-3">
                            <div id="article">
                                <figure>
                                    <img class="img-responsive" src="http://i.imgur.com/74aBLNQ.jpg" />
                                </figure>
                                <h4><a href="#">About surviving despite of everything</a></h4>
                                <div id="meta" class="row">

附言我使用的是 Bootstrap 3。

Answer 1

首先，ID 是唯一，而您正在复制 ID，因此请改用类。

由于您使用的是 Bootstrap ，因此缺少包装 .row 和 col-*-* 的 .container。

然后，要有相等的 height 而不是那个 hack，可以使用新的灵活布局，它是 flexbox 然后是 box-shadow 会出现

body {
  background: #ebebeb;
}
.row {
  display: flex
}
.article-container {
  padding: 1em;
  background: #ddd;
  display: flex
}
.article {
  padding: 0;
  background: #FFF;
  height: auto;
  box-shadow: 0 1px 3px 0 rgba(0, 0, 0, .2)
}
.article figure {
  max-width: 100%;
  height: auto;
}
.article figure img {
  /*height: 30%;*/
}
.article h4 {
  padding: 1em;
}
.article h4 a {
  text-decoration: none;
  color: #000;
}
.article h4 a:hover {
  text-decoration: underline;
}
.meta {
  color: #ccc;
  width: 100%;
  padding-left: 1em;
}
.meta a {
  text-decoration: none;
  color: #ccc;
}
.meta a:hover {
  text-decoration: underline;
}
.section-header {
  height: 40px;
  width: 100%;
  background: #FFF;
  display: table;
  border-left: 5px #FFC640 solid;
  margin-left: 0;
  margin-top: 2em;
  box-shadow: 0 1px 3px 0 rgba(0, 0, 0, .2)
}
.section-header h4 {
  padding-left: 1em;
  vertical-align: middle;
  display: table-cell;
}
