如何使相对对象始终位于 div [HTML/CSS] [重复] 的底部

【中文标题】如何使相对对象始终位于 div [HTML/CSS] [重复] 的底部

【英文标题】：How can I make a relative object always be on the bottom of a div [HTML/CSS] [duplicate]

【发布时间】：2020-10-30 15:09:42

【问题描述】：

所以我正在为产品制作卡片，但由于产品的某些高度较大，See offer 按钮不会到达底部。

这里有一些图片作为我的问题的一个例子

我将背景更改为蓝色，以便更好地可视化问题。 正如您在第一张卡片中看到的，标题有点短，使得按钮不像图 2 那样位于底部。

这是我的代码

<style>body 
  position: relative;


.see_offer 
  height: 50px;
  background-color: black;
  border-bottom-left-radius: 5px;
  border-bottom-right-radius: 5px;


.see_offer span 
  position: relative;
  left: calc(50% - 39.93px);
  top: calc(50% - 9.2px);

所以我的问题是有什么办法可以让它从 div 的底部始终保持 0px？

【参考方案1】：

给父元素position: relative 和子元素position: absolute; bottom: 0; 应该可以解决问题。
