HTML and CSS Reference
In-Depth Information
1.3 Specifying the Language
You want to specify the primary language of your web page.
Add the lang attribute and appropriate value to your opening html element:
<html lang="en" >
Browsers, screen readers, and other user agents use the lang attribute to determine the
language in which the content should be interpreted. The example above specifies
English via the en value.
Declaring a document's primary language isn't a requirement for HTML5 (or any of
the previous versions, for that matter). It is, however, a good practice for both usability
and accessibility.

1.4 Optimizing <script>s and <link>s
You want to reference JavaScripts and include links to external CSS files in your web
page as simply as possible.
Include script and link declarations, but without the type attribute:
<link rel="stylesheet" href="styles.css" />
<script src="scripts.js"></script>
HTML5 requires only the minimum amount of information needed for user agents. In
previous versions of HTML, both CSS link s and script s required the type attribute to
indicate the language. If you forgot to include type , though, most browsers assumed
the correct value.
