## 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 additional CSS.
|
|
|
|
{{< highlight html >}}
|
|
<div class="fixed-top">...</div>
|
|
{{< /highlight >}}
|
|
|
|
## 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 additional CSS.
|
|
|
|
{{< highlight html >}}
|
|
<div class="fixed-bottom">...</div>
|
|
{{< /highlight >}}

## 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.
|
|
|
|
{{< highlight html >}}
|
|
<div class="sticky-top">...</div>
|
|
{{< /highlight >}}
|
|
|
|
## Responsive sticky top
|
|
|
|
Responsive variations also exist for `.sticky-top` utility.
|
|
|
|
{{< highlight html >}}
|
|
<div class="sticky-sm-top">Stick to the top on viewports sized SM (small) or wider</div>
|
|
<div class="sticky-md-top">Stick to the top on viewports sized MD (medium) or wider</div>
|
|
<div class="sticky-lg-top">Stick to the top on viewports sized LG (large) or wider</div>
|
|
<div class="sticky-xl-top">Stick to the top on viewports sized XL (extra-large) or wider</div>
|
|
{{< /highlight >}}
