repeat() in Grid Context
repeat(count, track-size) is a CSS Grid function that generates multiple track definitions without repetition. It works inside grid-template-columns and grid-template-rows.
repeat() with Fixed Count
Create 4 equal columns:
<div class="grid">
<div>1</div><div>2</div><div>3</div><div>4</div>
</div>repeat() with Pattern
Repeat a pattern of tracks:
<div class="striped-grid">
<div>A</div><div>B</div><div>C</div><div>D</div><div>E</div><div>F</div>
</div>minmax() Inside Tracks
minmax(min, max) defines a track size range:
<div class="grid">
<div>1</div><div>2</div><div>3</div>
</div>auto-fit with minmax()
The responsive grid recipe:
<div class="cards">
<div>Card A</div><div>Card B</div>
</div>minmax(min-content, max-content)
Track sizes can use intrinsic sizing keywords:
<div class="labels">
<div>Label</div><div>Value</div>
</div>minmax() in Rows
Use minmax() for rows to allow content-driven height with a minimum:
<div class="gallery"><div>1</div><div>2</div></div>fit-content() for Columns
fit-content(max) makes a track as wide as its content up to a specified maximum — like max-content but capped:
<div class="layout"><div>Sidebar</div><div>Main</div></div>Combining repeat() and Named Lines
Repeat named lines to address individual columns by name:
<div class="grid">
<div>1</div><div>2</div><div>3</div><div>4</div>
</div>auto-fill with minmax for Fixed Items
When items should not stretch beyond their natural size:
<div class="gallery">
<div>1</div><div>2</div><div>3</div>
</div>fr vs Percentages in Grid
Unlike percentages, fr units automatically account for gap space. repeat(3, 1fr) with gap: 24px gives 3 truly equal columns. Percentages would need calc() to subtract gap.

Recap
repeat(count, track) generates multiple tracks without repetition. minmax(min, max) defines flexible track size ranges. The repeat(auto-fit, minmax(280px, 1fr)) pattern is the most powerful responsive grid — zero media queries, automatically responsive columns. Use fit-content(max) for content-aware sidebar columns.
