-    <h3>Google Maps</h3>
-    <p>If you're using Google Maps on a Bootstrapped project, you might run into some display problems due to our use of <code>* { box-sizing: border-box; }</code>. Previously, you may have also ran into issues with the use of <code>max-width</code> on images. The following snippet should avoid all those problems.</p>
+    <h3>Box-sizing</h3>
+    <p>Certain third party tools—such as Google Maps—have trouble working out of the box with Bootstrap due to our use of <code>* { box-sizing: border-box; }</code>. Use the following snippet to override it when necessary.</p>

  *
- * Wrap your Google Maps embed in a `.google-map-canvas` to reset Bootstrap's
- * global `box-sizing` changes. You may optionally need to reset the `max-width`
- * on images in case you've applied that anywhere else. (That shouldn't be as
- * necessary with Bootstrap 3 though as that behavior is relegated to the
- * `.img-responsive` class.)
+ * Wrap your third party code in a `.reset-box-sizing` to override Bootstrap's
+ * global `box-sizing` changes.
