Language
The language of a page, and even parts of a page, is very important to users of assistive technology like screen readers.
This document has a lang="en-gb" attribute on the <html> element. This ensures screen readers, search engines and other machines know what language the page is written in.
It is possible to define a passage on a page in another language using the lang on an element within the document.
Note: the lang attribute does not work on a semantically meaningless elements like <div> or <span>.
