在图像上显示项目

flexbox image css html

usernameabc · 技术社区 · 6 年前

我打开了以下代码 codepen page . (包括用于代码运行目的-在代码段中不起作用)目标是能够显示 <div class="item__boxes"> 元素的底部 <div class="item"> .

问题

我该如何显示 <DIV class=“项目框”> 元素的底部 <DIV class=“item”> ?

目标:

作为 <div class="item__text"> 由于其中的内容而增加,文本和 <DIV class=“项目框”> .
<DIV class=“项目框”> 应始终显示在 <DIV class=“item”> 不考虑断点的元素。

当前问题

期望输出

代码

.item {
  position: relative;
}
.item__wrapper {
  max-width: 50%;
  position: relative;
}
.item__img img {
  width: 100% !important;
}
.item__text {
  position: absolute;
  background: rgba(238, 238, 238, 0.5);
  padding: 64px;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  z-index: 5;
  display: flex;
  flex-direction: column;
  justify-content: center;

我玩弄过你的密码。为了总是有一些填充物,不管有多宽,你必须使用文本的相对位置和绝对位置的图像。由于衬垫底部的宽度不同,所以我建议您 将图像作为 background-image 并将背景图像的大小设置为 cover 在CSS中 ,这样无论屏幕有多宽/窄/高/短,都不会有间隙。我尝试了80%宽度的给定代码,并将填充设置为33%(我没有将背景图像代码放入),50%,初始宽度,不需要底部填充。

由于CSS结构的原因,代码片段不会运行,但我还是将其包含进来以供将来参考。这里是一个 codepen link 和A second one

希望这有帮助
