如何从模糊背景图像中删除白色边框

如何从背景图像中删除白色模糊边框.

CSS,我尝试添加保证金:-10px,但它不起作用

.background-image {
  background: no-repeat center center fixed; 
   background-image: url('https://img.php1.cn/3cd4a/1eebe/cd5/d84f9786330d9e41.png') ; 
  background-size: cover;
  display: block;
  height: 100%;
  left: -5px;
  top:-5px;
  bottom:-5px;
  position: fixed;
  right: -5px;
  z-index: 1;
  margin:0px auto;
  -webkit-filter: blur(5px);
  -moz-filter: blur(5px);
  -o-filter: blur(5px);
  -ms-filter: blur(5px);
  filter: blur(5px);
  -webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;

 }

最简单的方法是添加transform:scale(1.1).在这里试试吧.

#overlay {
 position: fixed;
 left: 22.5em;
 top: 3em;
 height: 75%;
 width: 50%;
 background: url("https://s-media-cacheak0.pinimg.com/originals/ae/b4/c5/aeb4c53cab2b550187644af503a0f17e.png");
 background-size: cover;
 filter: blur(9px);
 transform: scale(1.1); 
}

我已经添加了溢出,填充甚至边距,但仍然没有解决问题.所以我试图在div之间给出图像标签.问题解决了.

CSS

 .background-image {
  background: no-repeat center center fixed; 
  background-size: cover;
  display: block;
  left: -5px;
  top:-5px;
  bottom:-5px;
  position: fixed;
  right: -5px;
  z-index: 1;
  -webkit-filter: blur(5px);
  -moz-filter: blur(5px);
  -o-filter: blur(5px);
  -ms-filter: blur(5px);
  filter: blur(5px);
  -webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;
  margin:-5px;

 }
