灰度PNG圖像

-1

，所以我試圖把一個過濾器：灰度我的PNG圖像，但它是不工作的一些原因。灰度PNG圖像

我切斷部從我的圖像（山，用photoshop，透明背景）。並把它放在我的背景圖片上。當我嘗試轉換旋轉我的山它正在工作，但是當我嘗試灰度它，它不工作。

這裏是我的HTML代碼：

<!DOCTYPE html> 
<html lang="en"> 
<head> 
<meta charset="UTF-8"> 
<link rel="stylesheet" href="css/style.css"> 
<title>Document</title> 
</head> 
<body> 

<div id="container"> 
<div id="vrouw"></div> 
<div id="hoofd"></div> 
<div id="berg"></div> 
</div> 


</body> 
</html>

這裏是我的CSS代碼：

您是否嘗試搜索了一下，再發表你的問題？ http://stackoverflow.com/questions/16340159/greyscale-background-css-images – Vel

在#container中添加-webkit-filter: grayscale(100%);filter: grayscale(100%);以使整體灰度。即使它在關鍵幀中工作。在這裏，我已經添加了演示

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

width: 801px; 
 
height: 1233px; 
 
margin: auto; 
 
z-index: 1; 
 
} 
 

 
#hoofd { 
 
background-image: url('https://www.google.co.in/logos/doodles/2016/jagadish-chandra-boses-158th-birthday-5756743989592064.2-hp.png');

它不工作;），讓我們說，當我把我的山上的圖像懸停，它的顏色透明的東西，我想要的任何顏色但不圖像本身。我可以旋轉，縮放與關鍵幀的圖像，但是當我想要灰度時，它不起作用。 – Sid

我已經添加了使用灰度幾個關鍵幀的演示。如果有幫助，接受答案，以便像你這樣的人可以輕鬆找到答案。 – jafarbtech

我試圖把灰度（bergk）不（huufd）;）所以你的代碼是不正確的;） – Sid

我現在不能試試這個，但你可以托盤這段代碼

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