Creating a Fuzzy Border in CSS 3 - css

Question

Here's my source image:
And my source image zoomed in:
Any thoughts on how to accomplish this with only CSS3? Notice the slight bleed upwards into the element.

Answer 1

Update: I've removed the vendor prefixes, since almost every browser that supports these properties do not need them. Dropping them is considered a best practice at this point.
See Caniuse page for border-radius and box-shadow.
the best (and only) way to do this is to use multiple box-shadows:
element {
box-shadow: rgba(0,0,0,0.2) 0px 2px 3px, inset rgba(0,0,0,0.2) 0px -1px 2px;
border-radius: 20px;
}
box-shadow works like this:
box-shadow: [direction (inset)] [color] [Horizontal Distance] [Vertical Distance] [size];
border-radius works like this:
border-radius: [size];
/*or*/
border-radius: [topleft/bottomright size] [topright/bottomleft size];
/*or*/
border-radius: [topleft] [topright] [bottomright] [bottomleft];
you can specify the Height an length of the curve like this:
border-radius: [tl-width] [tr-width] [br-width] [bl-width] / [tl-height] [tr-height] [br-height] [bl-height];

Answer 2

It's just using two box shadows, one inset and the other outset, i.e:
.box {
width: 100px;
height: 100px;
box-shadow: 0 3px 6px rgba(0,0,0,0.3), inset 0 -3px 3px rgba(0,0,0,0.1);
border: solid #ccc 1px;
border-radius: 10px;
margin: 50px 0 0 50px;
}

Answer 3

This is actually done with two CSS3 box-shadows.
CSS:
#fuzz
{
height: 100px;
width: 100px;
border-radius: 5px;
border: 1px solid #333;
box-shadow: 0px 0px 5px #333, inset 0px 0px 2px #333;
}
You can see it in action when i get back to real computer to edit the fiddle :-) (using my tablet now)
Obviously change the colors to your taste :)

Answer 4

Look at css3 property border-radius. It has options for x and y offset color and the blur radius. In your case a greyish color no offset and blur if 4px ought to work.

Answer 5

I'm a bit late but, yes, use border radius and box-shadow(s) and you should be good to go.
.block {
border-radius:6px;
box-shadow: inset 0px 0px 2px 2px #aaa, 3px 3px 5px 0px #eee;
}

Answer 6

Try adding a border-radius and a text-shadow in your css.
.box {
border-radius:20px;
text-shadow:2px 2px black;
}
Hope this helps.

Answer 7

You can probably just get away with setting the border to a light colour and outline to a darker colour, then just set the border-radius. Note I haven't tested this, and if memory serves the outline does not curve with border-radius. Also note that border-radius requires several attributes to be set to become cross-browser compatible. Refer to http://perishablepress.com/press/2008/11/24/perfect-rounded-corners-with-css/ for more info.
If this fails, you could always use an inner-div, which you set to position absolute, left 0, right 0, top 0 and bottom 0 and then use that as either the inner or outer border. Setting the border-radius will definitely work then.
