+### Enclosed
+
+Use the `variant="enclosed"` class to give your navigation items a subtle border and rounded styling.
+
+::: demo
+<CNav variant="enclosed">
+  <CNavItem>
+    <CNavLink href="#" active>
+      Active
+    </CNavLink>
+  </CNavItem>

+### Enclosed pills 
+
+Use the `variant="enclosed-pills"` to achieve a pill-style appearance for each nav item, using pill-shaped borders and smoother outlines.

+::: demo

 ### Fill and justify
 
 Force your `.nav`'s contents to extend the full available width one of two modifier classes. To proportionately fill all available space with your `.nav-item`s, use `layout="fill"`. Notice that all horizontal space is occupied, but not every nav item has the same width.
