<div class="grid grid-cols-3 gap-2 place-items-start h-48 ..."> <div>1</div> <div>2</div> <div>3</div> <div>4</div> <div>5</div> <div>6</div> </div>

<div class="grid grid-cols-3 gap-2 place-items-end h-48 ..."> <div>1</div> <div>2</div> <div>3</div> <div>4</div> <div>5</div> <div>6</div> </div>

<div class="grid grid-cols-3 gap-2 place-items-center h-48 ..."> <div>1</div> <div>2</div> <div>3</div> <div>4</div> <div>5</div> <div>6</div> </div>

Stretch

<div class="grid grid-cols-3 gap-2 place-items-stretch h-48 ..."> <div>1</div> <div>2</div> <div>3</div> <div>4</div> <div>5</div> <div>6</div> </div>

Responsive

To place items at a specific breakpoint, add a {screen}: prefix to any existing place-items utility. For example, use md:place-items-center to apply the place-items-center utility at only medium screen sizes and above.

<div class="place-items-start md:place-items-center"> <!-- ... --> </div>

Customizing

Variants

By default, only responsive variants are generated for place-items utilities.

You can control which variants are generated for the place-items utilities by modifying the placeItems property in the variants section of your tailwind.config.js file.

For example, this config will also generate hover and focus variants:

 // tailwind.config.js  module.exports = {   variants: {   extend: {  // ... +  placeItems: ['hover', 'focus'],   }   }  }

Disabling

If you don't plan to use the place-items utilities in your project, you can disable them entirely by setting the placeItems property to false in the corePlugins section of your config file:

 // tailwind.config.js  module.exports = {   corePlugins: {  // ... +  placeItems: false,   }  }
