Hi kiddo! Have you ever seen a picture or a painting? Well, there is something called "Formalism" in art, which means that the most important thing about a picture or a painting is how it looks (its form). So, Formalism is like being more interested in how the colors, the lines, the shapes, and the texture of the picture or painting are put together, rather than what the picture is about.
It's a bit like when you play with your building blocks. You can make all sorts of things like castles, cars, and animals, but what matters most is how you build it (the form) and how it looks. So with formalism in art, people care about the way a painting or picture is put together, not necessarily what it represents.
Some people like art that has a lot of bright colors, big shapes, and weird lines. Other people like art that is more realistic and looks like real life. Formalism just means that people care more about the way the art looks and feels than just what it is about.
Overall, formalism is all about looking at art in a different way and trying to see what makes it unique and interesting. It's like looking at a puzzle and enjoying the way the pieces fit together, rather than just trying to solve it.
