This commit adds HTML Opt-Groups separating Games and Animations on the web demo sample dropdown menu. There are also a few tiny styling changes. Mainly the addition of a transition duration to the logo image, as well as changing "max-device-width" to "max-width" on a media query so that the "mobile" view is shown if you scale down the window on desktop browsers.
