Utopia Grid Layout

This project's grid system with fluid spacing

Configuration

Generated from: https://utopia.fyi/grid/calculator?c=360,18,1.2,1240,20,1.25,5,2,&s=0.75|0.5|0.25,1.5|2|3|4|6,s-l&g=s,l,xl,12

Grid Variables

Location: css/styles/grid.css

:root {
  --grid-max-width: 77.50rem;
  --grid-gutter: var(--space-s-l, clamp(1.125rem, 0.5625rem + 2.5vw, 2.5rem));
  --grid-columns: 12;
}
VariableValueDescription
--grid-max-width77.50rem (1240px)Maximum content width
--grid-guttervar(--space-s-l)Fluid gutter: 18px → 40px
--grid-columns12Column count

Utility Classes

.u-container

Centers content with fluid horizontal padding.

.u-container {
  max-width: var(--grid-max-width);
  padding-inline: var(--grid-gutter);
  margin-inline: auto;
}

Usage:

<div class="u-container">
  <!-- Content constrained to 1240px max width -->
</div>

.u-grid

Basic grid with fluid gap.

.u-grid {
  display: grid;
  gap: var(--grid-gutter);
}

Usage:

<div class="u-grid">
  <div>Grid item</div>
  <div>Grid item</div>
</div>

Usage Patterns

Combine Container and Grid

<div class="u-container">
  <div class="u-grid" style="grid-template-columns: repeat(3, 1fr);">
    <div>Item 1</div>
    <div>Item 2</div>
    <div>Item 3</div>
  </div>
</div>

Auto-fit Responsive Grid

.card-grid {
  display: grid;
  grid-template-columns: repeat(auto-fit, minmax(min(300px, 100%), 1fr));
  gap: var(--grid-gutter);
}

Using Space Tokens for Custom Gaps

.tight-grid {
  display: grid;
  gap: var(--space-s);
}

.loose-grid {
  display: grid;
  gap: var(--space-xl);
}

What's NOT Defined

The following patterns are not currently in the CSS:

  • Column span classes (e.g., .col-span-6)
  • Named grid areas
  • Subgrid utilities
  • Layout primitives (stack, cluster, sidebar)

Add these as needed based on project requirements.
