Positions
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">
<button class="btn btn-primary">Button</button>
</div>
Use .absolute
to move elements out of the default document flow.
<div class="relative mb4">
<button class="btn btn-primary">Button</button>
<div class="absolute bg-white border rounded">
<a href="#" class="block btn">Dropdown Action</a>
<a href="#" class="block btn">Action</a>
<a href="#" class="block btn">Action</a>
</div>
</div>
Use .fixed
to position an element relative to the viewport.
<button class="fixed btn btn-primary">
Button
</button>
Note: Fixed positioning is notoriously tricky to use well and can lead to inaccessible content and unwanted side effects. Use fixed positioning with caution.
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.
<button class="fixed top-0 right-0 m2 btn btn-primary">
Button
</button>
To fill an entire width or height, use opposing directions.
Fixed bar
<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.
Fixed bar
<div class="fixed z2 top-0 left-0 right-0 p2 white bg-black">
Fixed bar
</div>
