Position utilities are helpful for quickly placing a component outside the normal document flow. Choose from a handful of fixed or sticky position classes as needed.
Fixed top
Position an element at the top of the viewport, from edge to edge. Be sure you understand the ramifications of fixed position in your project; you may need to add aditional CSS.
<div class="fixed-top">...</div>Fixed bottom
Position an element at the bottom of the viewport, from edge to edge. Be sure you understand the ramifications of fixed position in your project; you may need to add aditional CSS.
<div class="fixed-bottom">...</div>Sticky top
Position an element at the top of the viewport, from edge to edge, but only after you scroll past it. The .sticky-top utility uses CSS’s position: sticky, which isn’t fully supported in all browsers.
<div class="sticky-top">...</div>
