在Firefox上制作灰度图像

Question

我被困在一个地方,我的HTML和CSS可以在Chrome和IE上运行,但不适用于Firefox.我已经通过CSS应用了灰度.

<div class="content_text"> 
    <img class="grpimg" src="../clients/2AEW%20Infratech.JPG" />
    <img class="grpimg" src="../clients/4APCTT.JPG" />
    <img class="grpimg" src="../clients/astonfield.PNG"/>
</div>

.content_text .grpimg{
    width:30%;
    height:30%;
    margin:7px;
    filter: grayscale(100%); /* Current draft standard */
    -webkit-filter: grayscale(100%); /* New WebKit */

    -ms-filter: grayscale(100%); 
    -o-filter: grayscale(100%); /* Not yet supported in Gecko, Opera or IE */ 
    filter: url(resources.svg#desaturate); /* Gecko */
    filter: gray; /* IE */
    -webkit-filter: grayscale(1); /* Old WebKit */
}

Answer 1

用这个

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"); /* Firefox 10+, Firefox on Android */

代替

filter: url(resources.svg#desaturate)
