+# Providers::Dimension
+
+A provider component that helps you to make a container fill the remaining space of the viewport.
+Usually, you would **use flexbox** to do so but for scenarios where this isn't possible you
+can use this component to make it easy to take up the remaining space.
+
+```hbs
+<Providers::Dimension as |p|>
+  <div style={{p.data.fillRemainingHeightStyle}}>
+    Fill remaining space
+  </div>
+</Providers::Dimension>
+```
+
+By default, this component will take up the remaining viewport space by taking the
+top of itself as the top-boundary and the `footer[role="contentinfo"]` as the
+bottom-boundary. In terms of Consul-UI this means _take up the entire space but
+stop at the footer that holds the consul version info at the bottom of the screen_.
+
+You can pass a different `bottomBoundary` if need be:
+
+```hbs preview-template
+<div class='h-48 relative flex border border-hds-consul-foreground'>
+  <div class='h-full w-24 relative'>
+    <div
+      class='absolute bottom-0 w-full h-12 bg-hds-consul-gradient-primary-start flex items-center justify-center'
+      id='bottom-boundary'
+    >
+      Boundary
+    </div>
+  </div>
+  <div class='flex-1'>
+    <Providers::Dimension @bottomBoundary='#bottom-boundary' as |p|>
+      <div
+        style={{p.data.fillRemainingHeightStyle}}
+        class='bg-hds-consul-surface flex items-center justify-center'
+      >
+        We could use flexbox here instead
+      </div>
+    </Providers::Dimension>
+  </div>
+</div>
+```
