HTML5 Doctype

Schema uses certain HTML elements and CSS properties that make use of HTML5 doctype. Please be sure to include it in all of your projects.

<!DOCTYPE html>

HTML5 Shiv/Shim

For older browsers, like IE9 and below, you'll need to include an HTML5 shim because there is little to no support for HTML5 features. This enables styling of HTML5 elements in those browsers, which do not allow elements to be styled without Javascript.

Google provides theirs through a CDN. Just put this link in the head section of your website.

<!DOCTYPE html>
        <!--[if lt IE 9]>
          <script src="//"></script>
