Update
I just realized that the desaturation is only working in Chrome. How do I make it work in FF, IE and other browsers? (Headline changed)
I'm converting a color picture to greyscale by following the suggestions here: Convert an image to grayscale in HTML/CSS
And it works great (in Chrome): http://jsfiddle.net/7mNEC/
<img src="https://imagizer.imageshack.us/v2/350x496q90/822/z7ds.jpg" />
// CSSS
img {
filter: url(~"data:image/svg+xml;utf8,<svg xmlns=\'http://www.w3.org/2000/svg\'><filter id=\'grayscale\'><feColorMatrix type=\'matrix\' values=\'0.3333 0.3333 0.3333 0 0 0.3333 0.3333 0.3333 0 0 0.3333 0.3333 0.3333 0 0 0 0 0 1 0\'/></filter></svg>#grayscale");
-webkit-filter: grayscale(100%);
-moz-filter: grayscale(100%);
-ms-filter: grayscale(100%);
-o-filter: grayscale(100%);
filter: gray;
}
img:hover {
filter: none;
cursor: pointer;
}
But I'm not able to remove the desaturation on e.g. mouse over.
Any ideas to what I'm doing wrong?
