Real CSS. Real crayons.

The stylesheet on the page isn't decoration — it's the instruction sheet. Children read the selector, find the matching shape in the drawing, and color it with the value the code asks for. By the end of a book, CSS syntax feels like a familiar friend.

  • Selectors
  • color & background-color
  • Classes & ids
  • Nesting basics
owl.css
h1 {
color: blue;
}
.star {
color: yellow;
}
.owl-body {
color: brown;
}
.leaves {
color: green;
}
.sky {
color: light blue;
}

Three steps per page

1

Read the stylesheet

Each page starts with a few friendly lines of real CSS printed right next to the drawing.

2

Match the selector

Every shape is labelled with a class or id — .leaves, #sun, .owl-body — just like in a real website.

3

Color it in

The value tells you which crayon to grab. Finish the page and you've read your first stylesheet.

The sandbox challenges are written by hand. If you spot a mistake, please email us at hello@colorcoded.fun.

One series, many worlds

Each edition keeps the same method and swaps the theme — and the lessons level up.
