The latest shipping version of Edge supports position: sticky and I've successfully tested it with Bootstrap 4 and it works as intended. I added IE10 in place of Edge in that note as I assume that IE10 also has the `position: relative` fallback. REF: https://caniuse.com/#search=sticky

## Common values
|
|
|
|
Quick positioning classes are available, though they are not responsive.
|
|
|
|
{% highlight html %}
|
|
<div class="position-static">...</div>
|
|
<div class="position-relative">...</div>
|
|
<div class="position-absolute">...</div>
|
|
<div class="position-fixed">...</div>
|
|
<div class="position-sticky">...</div>
|
|
{% endhighlight %}
|
|
|
|
## 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.
|
|
|
|
{% highlight html %}
|
|
<div class="fixed-top">...</div>
|
|
{% endhighlight %}
|
|
|
|
## 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.
|
|
|
|
{% highlight html %}
|
|
<div class="fixed-bottom">...</div>
|
|
{% endhighlight %}
|
|
|
|
## 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>
|
|
{% endhighlight %}
