Usage

Use the {top|right|bottom|left|inset}-0 utilities to anchor absolutely positioned elements against any of the edges of the nearest positioned parent.

Combined with Tailwind’s padding and margin utilities, you’ll probably find that these are all you need to precisely control absolutely positioned elements.

<!-- Span top edge -->
<div class="relative h-32 w-32 ...">
  <div class="absolute inset-x-0 top-0 h-16 ...">1</div>
</div>

<!-- Span right edge -->
<div class="relative h-32 w-32 ...">
  <div class="absolute inset-y-0 right-0 w-16 ...">2</div>
</div>

<!-- Span bottom edge -->
<div class="relative h-32 w-32 ...">
  <div class="absolute inset-x-0 bottom-0 h-16 ...">3</div>
</div>

<!-- Span left edge -->
<div class="relative h-32 w-32 ...">
  <div class="absolute inset-y-0 left-0 w-16 ...">4</div>
</div>

<!-- Fill entire parent -->
<div class="relative h-32 w-32 ...">
  <div class="absolute inset-0 ...">5</div>
</div>

<!-- Pin to top left corner -->
<div class="relative h-32 w-32 ...">
  <div class="absolute left-0 top-0 h-16 w-16 ...">6</div>
</div>

<!-- Pin to top right corner -->
<div class="relative h-32 w-32 ...">
  <div class="absolute top-0 right-0 h-16 w-16 ...">7</div>
</div>

<!-- Pin to bottom right corner -->
<div class="relative h-32 w-32 ...">
  <div class="absolute bottom-0 right-0 h-16 w-16 ...">8</div>
</div>

<!-- Pin to bottom left corner -->
<div class="relative h-32 w-32 ...">
  <div class="absolute bottom-0 left-0 h-16 w-16 ...">9</div>
</div>

Responsive

To position an element only at a specific breakpoint, add a {screen}: prefix to any existing positioning utility. For example, adding the class md:inset-y-0 to an element would apply the inset-y-0 utility at medium screen sizes and above.

<div class="relative h-32 ...">
  <div class="absolute inset-0 md:inset-y-0 ..."></div>
</div>

For more information about Tailwind’s responsive design features, check out the Responsive Design documentation.

Customizing

Top / Right / Bottom / Left scale

By default, Tailwind provides top/right/bottom/left/inset utilities for a combination of the default spacing scale, auto, full as well as some additional fraction values.

You can change, add, or remove these by editing the theme.inset section of your tailwind.config.js file.

  // tailwind.config.js
  module.exports = {
    theme: {
      inset: {
        '0': 0,
        // ...
-       '64': '16rem',
+       '1/5': '20%',
      }
    }
  }

Negative values

If you’d like to add any negative top/right/bottom/left classes that take the same form as Tailwind’s negative margin classes, prefix the keys in your config file with a dash:

  // tailwind.config.js
  module.exports = {
    theme: {
      extend: {
        inset: {
+         '-16': '-4rem',
        }
      }
    }
  }

Tailwind is smart enough to generate classes like -top-16 when it sees the leading dash, not top--16 like you might expect.

Variants

默認情況下, 只有 響應式 的 top, right, bottom, left, and inset 變化模式 (variants) 會產生。

tailwind.config.jsvariants 區塊中變更 inset 屬性來決定有哪些變化模式會生成。

舉個例子來說,這個設定將會生成 響應式 和 hover 的變化模式。

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

Disabling

如果你不打算在專案中使用 top, right, bottom, left, and inset 功能,可以在你的設定檔裡的 corePlugins 屬性中將 inset 設定為 false 來停用功能:

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