I'm trying to get an effect like an inset drop shadow effect in CSS that looks like the following image:
(source: gyazo.com)
Does any body know how I can get that effect with CSS?
The key here is multiple box shadows, a larger darker one inset from the top left and a very subtle shadow below thats slightly brighter than the background.
Notice the form of box-shadow is "x-offset, y-offset, blur, color"
Learn to use the blur amounts and multiple shadows and you can make some really nice effects.
Example style (for display on a background of #222):
.button {
display:inline-block;
padding: 10px 15px;
color: white;
border-radius: 20px;
box-shadow: inset 2px 3px 5px #000000, 0px 1px 1px #333;
}
