Convert an image to grayscale in HTML/CSS
Is there a simple way to display a color bitmap in grayscale with just HTML/CSS?
It doesn't need to be IE-compatible (and I imagine it won't be) -- if it works in FF3 and/or Sf3, that's good enough for me.
I know I can do it with both SVG and Canvas, but that seems like a lot of work right now.
Is there a truly lazy person's way to do this?

Support for CSS filters has landed in Webkit. So we now have a cross-browser solution.
img {
filter: gray; /* IE6-9 */
filter: grayscale(1); /* Microsoft Edge and Firefox 35+ */
-webkit-filter: grayscale(1); /* Google Chrome, Safari 6+ & Opera 15+ */
}
/* Disable grayscale on hover */
img:hover {
filter: none;
-webkit-filter: grayscale(0);
}
