// ✅ NEW: For content-driven sizing
.tags {
  @include grid-intrinsic(auto-fit, max-content);
}

2. Combine New Mixins for Power

.advanced-grid {
  @include grid-container(12, 1rem);
  @include grid-auto-flow(row, true); // Dense packing
  @include grid-auto-rows(minmax(100px, auto));

  .item {
    @include grid-self(center, start);
  }

  .full-width {
    @include grid-full-width;
  }
}

3. Mobile-First with New Features

.responsive-cards {
  // Mobile: Stack
  @include grid-container(1, 1rem);

  @media (min-width: 640px) {
    // Tablet: 2 columns
    @include grid-cols(2, 1rem);
  }

  @media (min-width: 1024px) {
    // Desktop: Auto-responsive with minmax control
    @include grid-minmax(280px, 350px, auto-fit, 2rem);
  }
}

4. Use New Alignment Shortcuts

// ✅ NEW: Concise centering
.hero {
  @include grid-place(center);
  min-height: 400px;
}

// ✅ NEW: Content alignment
.spaced {
  @include grid-cols(3);
  @include grid-place-content(space-between);
}

// ✅ NEW: Grid content positioning
.centered-grid {
  @include grid-cols(3);
  @include grid-content(center, center);
  height: 100vh;
}

❓ FAQ

What's the difference between v1.0 and v1.2?

Version 1.2 adds 20 powerful new mixins (nearly doubling the library), introduces modern CSS features like container queries, provides more granular control over grid behavior, and includes enhanced alignment shortcuts and improved masonry layouts.

Can I use the new container-aware features?

Yes! The grid-container-aware mixin uses CSS Container Queries, which are supported in Chrome 105+, Firefox 110+, and Safari 16+. For older browsers, use traditional media queries as a fallback.

Should I use `grid-place` or `grid-center`?

Use grid-place(center) when you want concise centering with flexibility
Use grid-center when you want explicit centering (clearer intent)
Both compile to the same CSS

How do I migrate from v1.0 to v1.2?

Version 1.2 is 100% backward compatible. All v1.0 mixins work identically. Simply update the library and optionally adopt new mixins where they improve your code.

Which new mixins should I learn first?

Start with these high-impact additions:

grid-full-width / grid-full-height - Instant spanning
grid-minmax - Better responsive control
grid-place - Concise alignment
grid-layer - Overlay elements
grid-auto-flow - Control item placement
