+# Apply Multiple Box Shadows To Single Element
+
+Multiple box-shadows can be applied to the same DOM element. The `box-shadow`
+property accepts a comma-separated list of `box-shadow` directives.
+
+Here is a pretty nasty looking example from the [MDN
+docs](https://developer.mozilla.org/en-US/docs/Web/CSS/box-shadow#Syntax):
+
+```css
+/* Any number of shadows, separated by commas */
+box-shadow: 3px 3px red, -1em 0 0.4em olive;
+```
+
+Here is a more practical [example](https://codepen.io/jbranchaud/pen/GRReaxo):
+
+```css
+box-shadow: 0 0 0 2px #4caf50,
+  0 3px 5px 0 rgba(0,0,0,0.5);
+```
+
+This gives the effect of a solid border with some shadow for depth.
+
+Multiple shadows has [pretty robust browser
+support](https://developer.mozilla.org/en-US/docs/Web/CSS/box-shadow#Browser_compatibility).
