How to make github style page transitions by pjax

Question

Once a time, I read an article said that github page transition is made by pjax, I checked jquery-pjax project. I think I have close to the answer, it must be something related with event pjax:start and pjax:end, but I still can't get it works, so I try to get some help here.

$('a.pjax').pjax('#main');
$('#main').bind('pjax:start', function(){$('#main').slideUp()})
  .bind('pjax:end'), function(){$('#main').slideDown()});

But it has no effects

Answer 1

Github use HTML5 features for the page transitions. That includes the new JS History API and CSS3 transitions. No jQuery involved except for standard event listening, selectors. The blog post is here with all the relevant links https://github.com/blog/760-the-tree-slider
