I would like to turn an entire website to grayscale. Of course, I can manually edit the CSS and adjust every single color
, background-color
& co. property, and I can adjust every single image in Photoshop.
But is there an easier way, e.g. by using pure CSS?
E.g., something such as putting a 100% x 100% overlay div
on top of your site that turns every color to grayscale?
Any hints?
Yes there is, just use filter grayscale
CSS
*{
-moz-filter: grayscale(100%);
-webkit-filter: grayscale(100%);
filter: gray; /* IE6-9 */
filter: grayscale(100%);
}
Note: You can apply this in any element (html, body, header, etc...)
