Question

我想用css实现如下图像的图像。我的意思是我想让图像背景出现但在前面图像应该是透明的。我的意思是它应该像模糊一样被覆盖。我想达到如下图像。

＆＃13;

img {
  -webkit-filter: blur(5px);
-moz-filter: blur(5px);
-o-filter: blur(5px);
-ms-filter: blur(5px);
filter: blur(5px);
position:fixed;
}

＆＃13;

<div><img src="http://i.imgur.com/v06GqMK.jpg" /></div>

＆＃13;

Answer 1

您可以使用CSS伪元素或其他html元素来实现此目的。这是一个使用伪元素的例子：在

之前

＆＃13;

.blur {
  position: relative;
  display: inline-block; /* make the div not 100% */
}
/* the 'blur' effect */
.blur:before {
  content: '';
  background-color: #000;
  opacity: 0.5;
  width: 100%;
  height: 100%;
  z-index: 1;
  position: absolute;
  top: 0;
  left: 0;
}
.blur img {
  display: block; /* remove bottom space */
}

＆＃13;

<div class="blur">
  <img src="http://i.imgur.com/v06GqMK.jpg" />
</div>
