Do you like GitHub’s Tree Slider? The new HTML5 History API (which really has nothing to do with HTML – it’s a JavaScript API) allows us to manage the URL changes while CSS3 transitions handle the sliding. Permalinks are always maintained, your back button works as expected, and it’s much faster than waiting for a full page load.
Take a look at The Tree Slider by GitHub, to see how to implement that. Basically they intercept your click, call pushState() to change the browser’s URL, load in data with Ajax, then slide over to it.
