Why This Matters

Sass Basics: Variables, Nesting, Mixins helps you build visual consistency. Reusable classes and a predictable spacing system make interfaces faster and cleaner to build.

Real-World Workflow

Teams usually begin with design tokens for colors, spacing, and type scale. This keeps new components consistent and avoids random values.

Over-specific selectors, excessive !important use, and mixed units create avoidable bugs. Mobile-first CSS keeps responsive behavior more stable.

  @include center;
  background: $primary;

  .title {
    color: white;
  }
}
