扩展 flexbox 容器不按下下面的 div

Question

我有一些元素将包含一个固定大小的图像和一些可变长度的文本，当文本大于 div 元素增长但不下推显示的元素的文本容器高度时，我注意到了一个令人讨厌的行为下面（Body 有带有方向列的 flex 显示）所以这将是更可取的结果，对吧？

这就是我要说的：https://imgur.com/a/MjwOxXX

注意上部是如何通过重叠在下部从下部占据空间的，而不是整个容器在下部生长并向下移动。

这是我的代码：

body{display:flex; flex-direction:column; height:auto; font-family:Roboto Slab; position:relative; scroll-bahaviour:smooth;}

Answer 1

我查看了您的代码，发现 .squared_content_texts_container 类将描述文本高度固定为 145 像素。这就是为什么当第一个盒子的高度增长时它没有调整父 div 的高度。

尝试从 .squared_content_texts_container 类中删除 145px 的高度，或者将 min-height 设置为 145px。

然后，三个 flex box 将在中间垂直对齐，但如果你想让它们顶部对齐，你必须使用 align-self: flex-start; .squared_content_container 类的样式。

请看这个 jsFiddle 的结果。 https://jsfiddle.net/katerynas/d3n5ksps/

 .squared_content_texts_container{
     width:100%;
     min-height:145px;
     display:flex;
     flex-direction:column;
     padding:10px;
     position:relative;
 }
 .squared_content_container{
     width:32%;
     height:auto;
     display:flex;
     flex-direction:column;
     margin:10px 0px;
     align-self: flex-start;
 }
