在图像上显示项目

Question

我在codepen page 上有以下代码。 （包括用于代码运行目的 - 在 sn-p 中不起作用）目标是能够在 <div class="item"> 的底部显示 <div class="item__boxes"> 元素。

问题

如何在<div class="item"> 底部显示<div class="item__boxes"> 元素？

目标：

1. 随着 <div class="item__text"> 的高度因其中的内容而增加，文本和 <div class="item__boxes"> 之间应始终有一些填充/边距。
2. 无论断点如何，<div class="item__boxes"> 都应始终显示在 <div class="item"> 元素的底部。

我玩过你的代码。 为了无论​​多宽都始终有一些填充，您必须在文本上使用相对定位并绝对定位图像。按照原样，padding-bottom 将根据它的宽度而有所不同，我建议您将图像包含为 background-image 并将背景图像的大小设置为 css 中的 cover ，这样无论你的屏幕多宽/窄/高/短，都不会出现缝隙。我以 80% 的宽度尝试了给定的代码，并将填充设置为 33%（我没有放入背景图像代码）在 50% 时，您的初始宽度，不需要底部填充。

sn-p 代码由于 css 结构而无法运行，但我还是将其包含在内以供将来参考。这是codepen link 和second one
