+
+## Focus Management
+Since the modal appears above the page, generally blocking interaction with the content below,
+it is important that the focus is move to an element within it.
+
+By default, it is the first focusable element within the modal that receives focus upon opening.
+However, You can decide to focus any other element by adding an `ngbAutofocus` attribute to it.
+
+## Examples
+
+<PostTabs>
+  <PostTabHeader slot="tabs" panel="varying-content">Varying Content</PostTabHeader>
+  <PostTabPanel name="varying-content">
+    <Source code={modalVaryingContent} language="typescript"/>
