html - 对齐 div 底部的元素

Question

我希望每个 div 的每个按钮“阅读更多”在同一级别对齐(在本例中是 div 的底部)。问题是我不想给 div 一个特定的高度，也不想更改任何标记或样式。

我可以使用一堆伪类选择器，但我希望保持代码简单，也许有更简单的方法。

Here's the working fiddle

.btn{
display: inline-block;
font-family: 'Oswald', sans-serif;  
font-weight: 400px;
padding: 5px 10px;
border: 2px solid #1AC4F8;
color: #1AC4F8;
cursor: pointer;}

Answer 1

Flexbox 可以做到这一点。

它将所有列设置为相同的高度，并告诉按钮位于每列的底部。

* {
  box-sizing: border-box;
  margin: 0;
  padding: 0;
}
*::before,
*::after {
  box-sizing: border-box;
}
.row {
  display: flex;
}
#services {
  background-color: rgb(265, 265, 265);
  color: #424242;
}
#services .col-3 {
  text-align: left;
  float: none;
  display: flex;
  flex: 0 0 25%;
  padding: 10px;
  flex-direction: column;
}
#sevices h3 {
  margin: 10px 0
}
.btn {
  margin-top: auto;
  display: inline-block;
  font-family: 'Oswald', sans-serif;
  font-weight: 400px;
  padding: 5px 10px;
  border: 2px solid #1AC4F8;
  color: #1AC4F8;
  cursor: pointer;
  -webkit-transition: color 0.8s, background-color 0.8s;
  transition: color 0.8s, background-color 0.8s
}
