CSS Question

Change color of PNG image via CSS?

Given a transparent PNG displaying a simple shape in white, is it possible to somehow change the color of this through CSS? Some kind of overlay or what not?

Answer

You can use filters by -webkit-filter and filter: Filters are very new to browsers and is only support in very modern browsers. You can change an image to grayscale, sepia and lot more (look at the example).

So you can now change color of a PNG file with filters now.

body {
    background-color:#03030a;
    min-width: 800px;
    min-height: 400px
}
img {
    width:20%;
    float:left; 
     margin:0;
}
/*Filter styles*/
.saturate {-webkit-filter: saturate(3); filter: saturate(3);}
.grayscale {-webkit-filter: grayscale(100%); filter: grayscale(100%);}
.contrast {-webkit-filter: contrast(160%); filter: contrast(160%);}
.brightness {-webkit-filter: brightness(0.25); filter: brightness(0.25);}
.blur {-webkit-filter: blur(3px); filter: blur(3px);}
.invert {-webkit-filter: invert(100%); filter: invert(100%);}
.sepia {-webkit-filter: sepia(100%); filter: sepia(100%);}
.huerotate {-webkit-filter: hue-rotate(180deg); filter: hue-rotate(180deg);}
.rss.opacity {-webkit-filter: opacity(50%); filter: opacity(50%);}
