In case you still haven't found a solution yourself, I've been tasked with doing a very similar thing. There are two ways of achieving this that I researched and choosing the right one mostly depends on the complexity of your design/expected result. Unfortunately I can't provide a link because the site won't be live for next couple of weeks.
This is what worked for me:
I used fullpage.js library to achieve 'full-page' scroll effect. You could also take a look at onepage-scroll.js and see which one fits you most - they don't differ that much in terms of functionality though.
Benefits of using fullpage.js (among other things):
- integration is quick and simple
- allows a lot of customisation through options hash
- provides callbacks when scroll to another section is triggered (before or after it happens)
- enables you to manually trigger a scroll via 'methods'
- works surprisingly good on iPad/iPhones. Probably on other mobile devices as well, although I can't fully confirm that since that
wasn't a requirement for my project.
Now when you've got section-to-section scrolling in place, what's missing is the animations. Considering that fullpage.js provides you with callbacks, it's as easy as adding a class when a transition to another section/slide happens and then using that class to trigger an animation of your choice through CSS. This is what worked for me without facing major problems.
For more advanced things:
If you're looking to build something more complex, then I strongly recommend that you take a look at tween.js. This is what google used on the landing page that you've provided in your question.
It's a very powerful tool hence it requires quite some setup + it moves animations to javascript, which might be a hassle. I would rather keep them in CSS where they belong and dont use javascript until I really need to.
FYI I also started with skrollr but it won't really work with 'fullpage scroll' because what it really does is disabling scrolling and animating body/html through translate. Skrollr bases it's behaviour on scroll event which will not fire if you use libraries I proposed.
EDIT:
It appears that you can actually use skrollr in par with fullpage.js. You can see the answer on how in it's FAQ site. Thanks to Alvaro for claryfing that! Even then, I wouldn't use skrollr unless you really need it for some advanced parallax scrolling effect - as said before, depends on your needs though. :)
Let me know if you have any doubts or something is not clear in my answer.
Good luck!
