This module includes basic positioning utilities to alter the default document flow.

Use positions with caution. They are often unnecessary and commonly misused.

Use .relative to create a new stacking context.

<div class="relative">
  <div>Hamburger</div>
</div>

Use .absolute to move elements out of the default document flow.

<div class="relative mb4">
  <div>Hamburger</div>
  <div class="absolute bg-white border rounded">
    <a href="#" class="block p1">Dropdown Action</a>
    <a href="#" class="block p1">Action</a>
    <a href="#" class="block p1">Action</a>
  </div>
</div>

Use .fixed to position an element relative to the viewport. Fixed positioning is notoriously tricky to use well and can lead to inaccessible content and unwanted side effects. Use fixed positioning with caution.

<div class="fixed">
  Hamburger
</div>

Note: fixed positioning has been disabled here for demonstration only.

To anchor to a particular side, use .top-0, .right-0, .bottom-0, or .left-0. Margin and padding utilities can be used to space elements apart.

<div class="fixed top-0 right-0 m2">
  Hamburger
</div>

To fill an entire width or height, use opposing directions.

<div class="fixed top-0 left-0 right-0 p2 white bg-black">
  Fixed bar
</div>

To ensure the desired stacking order, use z-index utilities.

<div class="fixed z2 top-0 left-0 right-0 p2 white bg-black">
  Fixed bar
</div>
