Bringing It All Together

Let's create a project structure that will be clean, protected, and modern.

/* 1. Organize layers */
@layer theme, components, widgets;

@layer theme {
  :root {
    --brand: oklch(60% 0.2 250);
  }
}

/* 2. Isolate widget */
@layer widgets {
  @scope (.dashboard-widget) {
    :scope {
      border: 1px solid var(--brand);
      border-radius: round(8.7px, 4px); /* Round to 8px or 12px */
    }
  }
}

/* 3. Bind tooltip */
.info-btn { anchor-name: --btn; }
.help-popup {
  position: absolute;
  position-anchor: --btn;
  top: anchor(bottom);
}

Course Summary:

You learned to write CSS that:

1. Doesn't conflict (@layer, @scope).
2. Is mathematically precise (round, abs).
3. Is interactive without JS (Anchor API, View Transitions).
4. Is visually flawless (OKLCH, COLRv1).
