Try to draw some pixels on the screen, pixel-art-react will generate the CSS code using box-shadow property.

Create as much drawings as you want in your project adding new frames and then check them in motion! it will use CSS keyframes to get the animation done and the CSS code will be ready to use in your HTML blocks.

Please check the following example:
