防止 div 在调整大小时重叠

Question

这些 div 有一个带有重叠文本的图像，它看起来像我想要的全尺寸。

但是，当我将大小时调整为小移动尺寸时，文本会出现在图像的顶部并且 div 会重叠。

我怎样才能使文本在调整大小时到达图像的底部，但最重要的是，容器不会重叠？

.container {
  position: relative;
  font-family: Arial;
  clear:both;
}

.text-block {
 clear:both;
  position: absolute;
  bottom: 30px;
  right: 10px;
  background-color: black;
  color: white;
  padding-left: 20px;
  padding-right: 20px;
}

<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<style>
.container {
  position: relative;
  font-family: Arial;
  clear:both;
}

.text-block {
 clear:both;
  position: absolute;
  bottom: 30px;
  right: 10px;
  background-color: black;
  color: white;
  padding-left: 20px;
  padding-right: 20px;
}
</style>
</head>
<body>

Answer 1

允许块级元素 (.text-blocks) 堆叠，因为它们自然会用于小视口。然后使用媒体查询在您首选的断点之后应用绝对定位。

.container {
  font-family: Arial;
}

.container img {
  display: block;
  width: 100%;
}

.text-block {
  background-color: black;
  color: white;
  padding-left: 20px;
  padding-right: 20px;
}

@media ( min-width: 48em ) {
  .container {
    position: relative;
  }
  
  .container img {
    width: 90%;
  }
  
  .text-block {
    position: absolute;
    bottom: 30px;
    right: 10px;
  }
}
