Position utilities
Position utilities place elements relative, absolute, fixed or sticky and pin them to edges.
In this page:
Syntax
<div class="position-relative">
<div class="position-absolute top-0 end-0">corner</div>
</div>Position utilities
Use .position-static, -relative, -absolute, -fixed and -sticky. Then edge helpers .top-0, .start-0, .end-0, .bottom-0 and .translate-middle position the element, and .fixed-top, .fixed-bottom and .sticky-top provide common shortcuts.
Absolute children need a relative parent.
Note:
An absolute element positions relative to its nearest positioned ancestor.
