Header fade – Not fading after recent update

Hi Robert,

Still loving the plugin! After the recent update, my transparent header no longer has the gradual fade into white as the user scrolls down the page. It immediately flashes to white.

I have the scroll distance set to 60px and this is the css I have:

selector{
transition:background 1s,height 1s;
}

Cheers, Gareth
