Question

我有4个按钮（＆＃34;阅读更多＆＃34;）在父母底部的同一级别对齐。

每个人都有不同的内容，所以为了给他们所有相同的尺寸，我使用了flexbox和绝对定位。

现在的问题是我希望每个父母都有背景颜色和按钮留在里面，但他们留在外面，因为我告诉他们在每一列的底部。

我有点卡住了，因为如果我取消按钮的绝对位置，父母会再次使用不同的尺寸，而且我不希望他们为响应式设计确定高度。

Answer 1

由于您已经在使用flexbox，为什么不使用flex属性将“Read more”按钮固定到底部。你不需要绝对定位。

尝试将.col-3设为嵌套的Flex容器：

.col-3 {
    display: flex;
    flex-direction: column;
    width: 25%;
    background-color: red
}

.btn {
    margin-top: auto;
}

.row {
  display: flex;
  flex-direction: row;
  padding-bottom: 40px;
}
.col-3 {
  display: flex;
  flex-direction: column;
  width: 25%;
  background-color: red
}
* {
  box-sizing: border-box;
  margin: 0;
  padding: 0;
}
*::before,
*::after {
  box-sizing: border-box;
}
#services {
  background-color: rgb(265, 265, 265);
  color: #424242;
}
#services .col-3 {
  padding: 0 20px;
}
#services .row .col-3:first-child {
  margin-left: 0
}
#services .right-align {
  text-align: right;
}
#services [class^="flaticon-"]:before,
#services [class^="flaticon-"]:after,
#services [class*="flaticon-"]:before,
#services [class*="flaticon-"]:after {
  font-size: 60px;
  margin-left: 0;
  -webkit-transition: color 0.8s;
  transition: color 0.8s;
}
#services [class*="flaticon"]:hover {
  color: #1AC4F8
}
#sevices h3 {
  margin: 10px 0
}
.btn {
  margin-top: auto;
  font-family: 'Oswald', sans-serif;
  font-weight: 400px;
  padding: 5px 10px;

  color: #1AC4F8;
  cursor: pointer;
  transition: color 0.8s, background-color 0.8s;

此解决方案将所有弹性项目放置在容器开头的列中（justify-content: flex-start是默认值）。然后使用flex auto margin将按钮固定在底部。
