+
+Box shadow on <abbr title="hypertext markup language">HTML</abbr> elements has been widely supported across most browsers for a while now, but I find the default options don't allow for much visual manipulation of the shadows in general.
+
+Let's take a look at a default configuration of `box-shadow`:
+
+
+    .box-container {
+        box-shadow: 0 4px 8px rgba(0,0,0,0.3);
+    }
+
+
+In the example above the first property number is the origin of the *x-axis*, the second number is the origin of the *y-axis* and the third is the amount of *blur*.
+
+We should also add some minimal styling to cleanup the `.box-container` a little bit for our example:
+
+
+    <div class="box-container"></div>
+
+
+    .box-container {
+        box-shadow: 0 4px 8px rgba(0,0,0,0.3);
+        /* Styles to make it less ugly */
+        background: white;
+        border-radius: 10px;
+        border: 1px solid #eee;
+        height: 200px;
+        padding: 10px;
+        position: relative;
+        width: 250px;
+    }
+
+
+Not bad - but we can do a lot better than this.
+
+## Please sir, I want some more (depth)
+
+We just need to add a simple child `div` (or use a `pseudo` element if you prefer) inside our main element we want to apply the shadow to:
+
+
+    <div class="box-container">
+        <div class="box-container-inner"></div>
+    </div>
+
+
+Now we make our inner child element `absolute` and set it's `height` and `width` dynamically to be slightly smaller than it's parent (percentages work best for this). 
+
+Remember to set this child element behind it's parent by adding `z-index: -1`.
+
+
+    .box-container {
+        /* No box-shadow needed on this element anymore */
+        /* Styles to make it less ugly */
+        background: white;
+        border-radius: 10px;
+        border: 1px solid #eee;
+        height: 200px;
+        padding: 10px;
+        position: relative;
+        width: 250px;
+    }
+
+
+## Inner Containers
+
+We also need to target the `box-container-inner` element set inside the current parent to reflect our custom shadow styling:
+
+
+    .box-container-inner {
+        bottom: 0;
+        /* The box-shadow is added here now */
+        box-shadow: 0 4px 12px rgba(0,0,0,0.3);
+        height: 94%;
+        left: 3%;
+        position: absolute;
+        width: 94%;
+        z-index: -1;
+    }
+
+
+Which will make the drop-shadow render with a little more realistic depth.
+
+
+## But wait - there's more!
+
+We could stop now and have a decent drop-shadow that is certainly easier on the eyes - but we can make this even better with one extra property - `filter:blur();`. 
+
+So your final code would look like this:
+
+
+    .box-container {
+        /* Styles to make it less ugly */
+        background: white;
+        border-radius: 10px;
+        border: 1px solid #eee;
+        height: 200px;
+        padding: 10px;
+        position: relative;
+        width: 250px;
+    }
+    
+    .box-container-inner {
+        bottom: 0;
+        box-shadow: 0 4px 12px rgba(0,0,0,0.3);
+        filter: blur(6px);
+        height: 94%;
+        left: 3%;
+        position: absolute;
+        width: 94%;
+        z-index: -1;
+    }
+
+
+Which renders out into a much smoother blend of a drop-shadow, creating a more realistic illusion of depth.
+
