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>

+ * 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.)

+    <p>If your navigation contains many links and comes before the main content in the DOM, add a <code>Skip to content</code> link immediately after your opening <code>&lt;body&gt;</code> tag. <a href="http://a11yproject.com/posts/skip-nav-links/">(read why)</a></p>
