Box shadow on HTML 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.

Box shadow on HTML 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 {

<div class="box-container"></div>

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>
+
+
<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.

We also need to target the box-container-inner element set inside the current parent to reflect our custom shadow styling:

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();.
