children 不在 parent div 内
children not staying inside parent divs
Fiddle: https://jsfiddle.net/uatzust3/
这是针对我的问题的 fiddle,您会发现 children 并没有留在 parent div card
中,而且我希望 div
占据 parent 的全宽,而他们没有占据。
另外,我应该从哪里学习最佳实践?我是社区的新手。提前致谢。
左边div(black_container)
内容不多,但是应该根据右边div(content_container)
的宽度来安排高度,同时一直在card
div.

将 .content_container
css 替换为:
.content_container {
display: inline-block;
padding: 3%;
vertical-align: top;
}
我认为 CSS 属性 position: absolute;
导致了这个问题。简而言之,absolute
position 将元素从其他元素流中移除;因此,它的高度被简单地忽略了,并且永远不会计算在您的 .card
容器中。
如果 child 是 absolute
,A parent 不能获取直接 child 的高度,因为 absolute
元素已从文档流中删除(比如 floats
),所以在这种情况下 "card" 甚至不知道 "content_container" 存在。

没有 flexbox 的解决方案:https://jsfiddle.net/OmarIsComing/eq4L86g9/3/
如果 flexbox
是一个选项,这很容易:
将 display: flex
添加到您的 card
将flex: 1
添加到content-container
参见下面的演示:

使用class卡体,这将保留卡内的内容。
