Design tokens with custom properties

Read first Task 39

--aicsa-orange declared once on :root becomes the brand colour everywhere.

How do you read a custom property in CSS?

The editor already contains a starting point. Change it until every check passes — the Next task button unlocks when it does.

What you start with

<style>
  :root { --brand: #FF6A00; }
</style>
<button>Apply</button>

Syntax reference

<style>
  :root { --brand: #FF6A00; }
  button { background: var(--brand); color:#fff; }
</style>
<button>Apply</button>

Read it, then write it yourself. Copy-paste teaches nothing.
