Top Drawer : A smooth dropdown menu with jQuery & CSS3

Top Drawer is a smooth dropdown menu for responsive web design. It is designed to demonstrate smoother reveal menus in small contexts using CSS3 rather than animating with JavaScript.Tap the menu icon in the top right. The click event will assign the class of active to the drawer container which alters the translate value to bring it into view. Modernizr will detect whether the user’s device is capable of CSS transforms, if it isn’t we simply show and hide the menu after the button is pressed – no point in animating if it isn’t going to work smoothly.
