+  <p class="lead">Extend form controls by adding text or buttons before, after, or on both sides of any text-based input. Use <code>.input-group</code> with an <code>.input-group-addon</code> to prepend or append elements to a single <code>.form-control</code>.</p>

+    <h4>Tooltips &amp; popovers in input groups require special setting</h4>
+    <p>When using tooltips or popovers on elements within an <code>.input-group</code>, you'll have to specify the option <code>container: 'body'</code> to avoid unwanted side effects (such as the element growing wider and/or losing its rounded corners when the tooltip or popover is triggered).</p>

+    <h4>Don't mix with other components</h4>
+    <p>Do not mix form groups or grid column classes directly with input groups. Instead, nest the input group inside of the form group or grid-related element.</p>

+  <p>Buttons in input groups are a bit different and require one extra level of nesting. Instead of <code>.input-group-addon</code>, you'll need to use <code>.input-group-btn</code> to wrap the buttons. This is required due to default browser styles that cannot be overridden.</p>
