Position
Use these shorthand utilities for quickly configuring the position of an element.
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.

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.
IE11 and IE10 will render position:
sticky
as position:
relative
. As such, we
wrap the styles in a @supports
query,
limiting the stickiness to only browsers
that can render it properly.
