+
+## Properties
+
+The properties available for the overflow of elements are the following:
+
+- `overflow` for the overflow of the content both horizontally and vertically.
+- `overflow-x` for the overflow of the content horizontally.
+- `overflow-y` for the overflow of the content vertically.
+
+The values available are the following:
+
+- `visible` (default) sets all of the content to be visible and will overflow the container if needed.
+- `auto` lets the browser decide what to do and will add scrollbar if needed.
+- `hidden` hides all of the content that would overflow the container, without any scrollbars.
+- `scroll` does not overflow the content and adds scrollbars to the container.
+
+<div className="alert alert-info alert-sm">
+  If one of the axis is defined as `visible`, and the other axis is defined as something else, then
+  the `visible` axis will be considered to be `auto`.
