CSS Filter Effects

It's not fully cross-browsers solution, but must work well in most modern browser.

<img src="image.jpg" />
<style>
    img:hover {
        /* Ch 23+, Saf 6.0+, BB 10.0+ */
        -webkit-filter: hue-rotate(240deg) saturate(3.3) grayscale(50%);
        /* FF 35+ */
        filter: hue-rotate(240deg) saturate(3.3) grayscale(50%);
    }
</style>

  • Edge, element or it's parent can't have negative z-index (see bug)
  • IE use old school way (link) thanks @Costa
