Rodrigo, First of all, you're awesome!!! And second, thanks for the detailed reply.
I started using web-development about 6months ago and about one month ago I started using JS. The code for the leaves (making them fly random directions and rotate) is not my own and I can't really answer your question:" In this regard a question: are those values changing constantly or they are a set that's calculated when the page loads?"
But your explanation about how you would get it done is very clear for me and the fact that it's possible to accomplish with GSAP.JS just brings a big smile on my face. As for your second question: "In terms of FF issues, could you tell us what are those issues?"
On FF this link: http://demo.chilipress.com/EpicForever/About5 ,, when hovered over one of the characters in the center, everything should become coloured with a 3sec transition. Just as is happening on Chrome. by the way, if you can help me with this, I would very VERY thankful. I believe I am using SVG to create a grey filter effect (with a class="grey"),, and when the character is hovered on I'm removingClass ("grey") with jQuery. On Chrome, Safari and Opera it works fine, but not one FF. On FF the transition happens instantly unfortunately. And when you wrote: "For the superhero image-filter though, that's webkit-specific so you can't use that in other browsers." Dit you mean I still have to use this vendor prefix even when working with GSAP.JS? Because the whole vendor prefix thing is one of the most stupid and waste-of-time matters I have come across since I started web-development. I understand how browsers have their own rules and why it is there, but I feel it is a bitch to work with them. I am trying to find a way to get all my animation and transformation and what not done without these damn vendor prefixes in my css all the time. So at this stage my question would be: When I use GSAP.JS, I don't need to use any vendor prefixes right? I mean, that's the whole point of GSAP.JS and that it's faster of course.
Look very much forward to your answer. Alex
