I don't think I need to duplicate it, looking at this again today, I think my problem is more with math,
I have these numbers:
$('#timeline').width() // 3840 - total width of my div with the years
$('#timeline').position().left // random number -
$(this).position().left // random number - when click on the year $(.year.year-active)
$(window).width() // 1920 - the size of my screen
var tl = new
TimelineLite();
tl.to($('#timeline'), 1, {x: /*I have no idea of what to put here*/ })
It'll slide my timeline, but how to calc it correctly :/
