+
+## 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 additional 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 additional 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 %}
