Your page uses an XHTML Mobile doctype declaration, which instructs browsers that your page is optimized for mobile and should render properly on all devices.
If you change the doctype, for example to <!DOCTYPE html> in order to use HTML5 features, configure a viewport with <meta name=viewport width=device-width> to keep the page's current behavior.
