Bootstrap follows common web standards and—with minimal extra effort—can be used to create sites that are accessible to those using <abbr title="Assistive Technology" class="initialism">AT</abbr>.

### Skip navigation
|
|
|
|
If your navigation contains many links and comes before the main content in the DOM, add a `Skip to main content` link [before the navigation](http://a11yproject.com/posts/skip-nav-links/). Using the `.sr-only` class will visually hide the skip link, and the `.sr-only-focusable` class will ensure that the link becomes visible once focused (for sighted keyboard users).
|
|
|
|
{% highlight html %}
|
|
<body>
|
|
<a href="#content" class="sr-only sr-only-focusable">Skip to main content</a>
|
|
<div class="container" id="content">
|
|
The main page content.
|
|
</div>
|
|
</body>
|
|
{% endhighlight %}
|
|
|
|
### Nested headings
|
|
|
|
When nesting headings (`<h1>` - `<h6>`), your primary document header should be an `<h1>`. Subsequent headings should make logical use of `<h2>` - `<h6>` such that screen readers can construct a table of contents for your pages.
