CSS Box Shadow for all browsers

Drop shadows are often used in web and print design to give elements more depth. Creating drop shadows for the Web used to require multiple images, created in image editing software and then attached to the page as CSS background images. This approached worked, but as well as being labour-intensive in terms of creating the necessary graphics, it also required bloating your markup with nested divisions, as each element could only have one image attached to it.

Used in casting shadows off block-level elements (like divs and span tags).

CSS code

.shadow {
  -moz-box-shadow:    3px 3px 5px 6px #ccc;
  -webkit-box-shadow: 3px 3px 5px 6px #ccc; 
  box-shadow:         3px 3px 5px 6px #ccc;
} 
  1. The horizontal offset of the shadow, positive means the shadow will be on the right of the box, a negative offset will put the shadow on the left of the box.
  2. The vertical offset of the shadow, a negative one means the box-shadow will be above the box, a positive one means the shadow will be below the box.
  3. The blur radius (optional), if set to 0 the shadow will be sharp, the higher the number, the more blurred it will be.
  4. The spread radius (optional), positive values increase the size of the shadow, negative values decrease the size. Default is 0 (the shadow is same size as blur).
  5. Color

 Example

Inner Shadow

.shadow {
   -moz-box-shadow:    inset 0 0 10px #000000;
   -webkit-box-shadow: inset 0 0 10px #000000;
   box-shadow:         inset 0 0 10px #000000;
}

Example

Internet Explorer Box Shadow

You need extra elements...

HTML Code

<div class="shadow1">
 <div class="content">
  Box-shadowed element
 </div>
</div>

CSS Code

.shadow1 {
 margin: 40px;
 background-color: rgb(68,68,68); /* Needed for IEs */

 -moz-box-shadow: 5px 5px 5px rgba(68,68,68,0.6);
 -webkit-box-shadow: 5px 5px 5px rgba(68,68,68,0.6);
 box-shadow: 5px 5px 5px rgba(68,68,68,0.6);

 filter: progid:DXImageTransform.Microsoft.Blur(PixelRadius=3,MakeShadow=true,ShadowOpacity=0.30);
 -ms-filter: "progid:DXImageTransform.Microsoft.Blur(PixelRadius=3,MakeShadow=true,ShadowOpacity=0.30)";
 zoom: 1;
}
.shadow1 .content {
 position: relative; /* This protects the inner element from being blurred */
 padding: 100px;
 background-color: #DDD;
}

One-Side Only

Using a negative spread radius, you can get squeeze in a box shadow and only push it off one edge of a box.

.one-edge-shadow {
 -webkit-box-shadow: 0 8px 6px -6px black;
    -moz-box-shadow: 0 8px 6px -6px black;
         box-shadow: 0 8px 6px -6px black;
}
