Hey kiddo, have you ever noticed that when you stand in front of a light source, like a lamp or the sun, there's a dark area right behind you? That's called your shadow!
Well, software shadows aren't too different. You know how on your computer, some boxes or buttons appear to have a darker background than others, especially when you hover over them? That's because a shadow effect has been added to them!
This effect is usually created by a computer program that calculates where the light source is coming from and generates these dark areas or shadows around objects on your screen that would realistically cast a shadow in real life.
The shadow effect helps us easily identify what's clickable or not, making it easier for us to interact with the software. It also gives a more realistic and visually pleasing dimension to buttons and other objects on our screens, making them look more like real objects that you can touch and manipulate.
So in summary, shadows in software are like the shadows we see in real life when light shines on objects, but instead, they are created by a computer program to add an extra layer of depth and usability to the software we use on our screens!
