# Grid Auto Rows

Utilities for controlling the size of implicitly-created grid rows.

## Quick reference

| Class | Description |
|-------|-------------|
| `auto-rows-auto` | `grid-auto-rows: auto` |
| `auto-rows-min` | `grid-auto-rows: min-content` |
| `auto-rows-max` | `grid-auto-rows: max-content` |
| `auto-rows-fr` | `grid-auto-rows: minmax(0, 1fr)` |

## Basic usage

### Sizing implicitly-created grid rows

Use the `auto-rows-{size}` utilities to control the size implicitly-created grid rows.

```html
<div class="grid grid-flow-row auto-rows-max">
  <div>01</div>
  <div>02</div>
  <div>03</div>
</div>
```

### Arbitrary values

If you need to use a one-off `grid-auto-rows` value that doesn't make sense to include in your theme, use square brackets to generate a property on the fly using any arbitrary value.

```html
<div class="grid grid-flow-row auto-rows-[minmax(0,_2fr)]">
  <!-- ... -->
</div>
```

## Applying conditionally

### Breakpoints and media queries

You can also use variant modifiers to target media queries like responsive breakpoints, dark mode, prefers-reduced-motion, and more. For example, use `md:auto-rows-min` to apply the `auto-rows-min` utility at only medium screen sizes and above.

```html
<div class="grid grid-flow-row auto-rows-max md:auto-rows-min">
  <!-- ... -->
</div>
```
