This app is also available as PWA and works fairly well on mobile devices.

You have to make the site preview in the bottom right look the same (and animate the same) as the page above. To do this, you should use a built-in CSS editor (bottom left) or even write page structure in a built-in HTML editor (top left).

You will get hints along the way and a list of mistakes when requested.

More info available in the help menu.

Currently, this game has only 2 levels so you can contribute by adding more, because I'm not into CSS that much now. Levels are very simple to make as they are meant to be short HTML + CSS snippets representing ie. navbar or form. You can look for examples and structure in /levels directory
