Used in casting shadows off block-level elements (like divs).
.shadow {
-moz-box-shadow: 5px 5px 5px #ccc;
-webkit-box-shadow: 5px 5px 5px #ccc;
box-shadow: 5px 5px 5px #ccc;
}
- 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.
- 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.
- The blur radius, if set to 0 the shadow will be sharp, the higher the number, the more blurred it will be.
- 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;
}

<div class="shadow1">
<div class="content">

</div>
</div>
.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; }
