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.

One series, many worlds

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