First of all, amazing grid and thank you for sharing.
Now, the problem. I am using this grid and when I click the image it pops up and everything is good, but when I scroll it the pop up with the original image and the details scrolls and don't stay on top. Or when I scroll down the grid and click an image that is way down on the grid I get a black screen unless I scroll to the top of the page where the pop up preview is stuck. I want it so that when I click the image it does not scroll, and when I look at your demo it works and on mine it scrolls.
(... you scroll and the black at the bottom shows up.)
(P.S. Ignore the spelling error in the image. ;P)
I think I know where the problem lies, but don't know how to fix it. So here is where I think it is.
Since I am using another Tympanus theme called "Page Stack" and that theme is not scrollable and I wanted to use your grid theme (which needs scroll), I made it scrollable by writing page.style.overflow = 'scroll';
into the following javascript for the navigation.
for(var i = 0; i < pagesTotal; ++i) {
var page = pages[i],
posIdx = stackPagesIdxs.indexOf(i);
if( current !== i ) {
classie.add(page, 'page--inactive');
if( posIdx !== -1 ) {
// visible pages in the stack
page.style.WebkitTransform = 'translate3d(0,100%,0)';
page.style.transform = 'translate3d(0,100%,0)';
}
else {
// invisible pages in the stack
page.style.WebkitTransform = 'translate3d(0,75%,-300px)';
page.style.transform = 'translate3d(0,75%,-300px)';
}
}
else {
classie.remove(page, 'page--inactive');
page.style.overflow = 'scroll';
}
