问题描述：

，所以我试图把一个过滤器：灰度我的PNG图像，但它是不工作的一些原因。灰度PNG图像

我切断部从我的图像（山，用photoshop，透明背景）。并把它放在我的背景图片上。当我尝试转换旋转我的山它正在工作，但是当我尝试灰度它，它不工作。

这里是我的HTML代码：

在#container中添加-webkit-filter: grayscale(100%);filter: grayscale(100%);以使整体灰度。即使它在关键帧中工作。在这里，我已经添加了演示

#container { 
 
position: relative; 
 
margin: 0 auto; 
 
width: 801px; 
 
height: 1233px;

width: 801px; 
 
height: 1233px;

它不工作;），让我们说，当我把我的山上的图像悬停，它的颜色透明的东西，我想要的任何颜色但不图像本身。我可以旋转，缩放与关键帧的图像，但是当我想要灰度时，它不起作用。 – Sid

我已经添加了使用灰度几个关键帧的演示。如果有帮助，接受答案，以便像你这样的人可以轻松找到答案。 – jafarbtech

我试图把灰度（bergk）不（huufd）;）所以你的代码是不正确的;） – Sid

答

我现在不能试试这个，但你可以托盘这段代码

img { 
-webkit-filter: grayscale(100%); /* Safari 6.0 - 9.0 */ 
filter: grayscale(100%); 
}
