Position

Utilities for controlling how an element is positioned in the DOM.

Default class reference

Class
屬性
staticposition: static;
fixedposition: fixed;
absoluteposition: absolute;
relativeposition: relative;
stickyposition: sticky;

Static

Use static to position an element according to the normal flow of the document.

Any offsets will be ignored and the element will not act as a position reference for absolutely positioned children.

Static parent

Absolute child

<div class="static ...">
  <p>Static parent</p>
  <div class="absolute bottom-0 left-0 ...">
    <p>Absolute child</p>
  </div>
</div>

Relative

Use relative to position an element according to the normal flow of the document.

Offsets are calculated relative to the element’s normal position and the element will act as a position reference for absolutely positioned children.

Relative parent

Absolute child

<div class="relative ...">
  <p>Relative parent</p>
  <div class="absolute bottom-0 left-0 ...">
    <p>Absolute child</p>
  </div>
</div>

Absolute

Use absolute to position an element outside of the normal flow of the document, causing neighboring elements to act as if the element doesn’t exist.

Offsets are calculated relative to the nearest parent that has a position other than static, and the element will act as a position reference for other absolutely positioned children.

Fixed

Use fixed to position an element relative to the browser window.

Offsets are calculated relative to the viewport and the element will act as a position reference for absolutely positioned children.

Sticky

Use sticky to position an element as relative until it crosses a specified threshold, then treat it as fixed until its parent is off screen.

Offsets are calculated relative to the element’s normal position and the element will act as a position reference for absolutely positioned children.

Responsive

To change how an element is positioned only at a specific breakpoint, add a {screen}: prefix to any existing position utility. For example, adding the class md:absolute to an element would apply the absolute utility at medium screen sizes and above.

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

Customizing

Variants

默認情況下, 只有 響應式 的 position 變化模式 (variants) 會產生。

tailwind.config.jsvariants 區塊中變更 position 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: {
        // ...
+       position: ['responsive', 'hover'],
      }
    }
  }

Disabling

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

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