What is Box Shadow?

Box shadow is one of those little known CSS tricks that can completely change how your element looks on the website. As the name sound, Box Shadow is all about creating shadow effect around box (container). Think of it as the digital version of a drop shadow you use to see in Photoshop.

It basically adds a shadow behind any element: like a card, button, image, or even a simple div: so it looks like it is floating above the page or has some real depth. Without it, everything can feel flat and stuck to the background; with a well-placed box shadow, things suddenly pop and look way more modern. It comes with various features like you can use inset or outset shadow, or you can use horizontal offset, vertical offset, blur radius and spread radius features. It is been around forever in CSS3 and pretty much every browser supports it now, so you are safe to use it anywhere.

Inset vs. Outset Box Shadow

Outset box shadows is the dafault shadow effect that psh the shadow outside the element. Just like natural phenomenon, shadow of any element is portrayed outside the object. The shadow sits behind the element and spreads outward, giving depth and separation from the background. This is what you use 95% of the time when you want something to popout.

Inset shadows, on the other hand, go inside the element, reverse of natural phenomenon. You just add the word inset in the CSS (or toggle it in a generator), and suddenly the shadow is carved into the box instead of flowing out. It creates a sunken or "pressed-in" feeling. These shadow is perfect for use cases like active or depressed button states, the old-school Windows XP look, but cooler now or input fields that look recessed.

box-shadow: 0 10px 20px rgba(0,0,0,0.15); box-shadow: inset 0 4px 8px rgba(0,0,0,0.2);
