I used a Codrops article/experiment to create an interactive environment for a local group to use at their conferences. The problem with this is the default interaction is not very intuitive. The template used Flickity.js and what seems like classie.js to create this sliding interface I am having trouble with.
The page can be found here:
Issue: The only way to activate the view-full is by clicking on the html element:
<h2 class=".stack-title">
// After the stack is active you should be able to activate the full view by clicking on the first .stack-item used to create the thumbnail below it. This entire div should be clickable. Users are touching everywhere all over the screen and not actually clicking the title for the desired action. I hope this makes sense.
In other words you should be able to click the stack-title and the image below the title of each stack to pull the stack into the full view mode on the screen. Then click the x or anywhere else on the screen to close the full view.
The following is located in main.js and the reference I found to create the events I am referring to.
//
function initEvents() {
stacks.forEach(function(stack) {
var titleEl = stack.querySelector('.stack-title');
// expand/close the stack
titleEl.addEventListener('click', function(ev) {
ev.preventDefault();
if( classie.has(stack, 'is-selected') ) { // current stack
if( classie.has(bodyEl, 'view-full') ) { // stack is opened
var closeStack = function() {
classie.remove(bodyEl, 'move-items');
onEndTransition(slider, function() {
classie.remove(bodyEl, 'view-full');
bodyEl.style.height = '';
flkty.bindDrag();
flkty.options.accessibility = true;
canMoveHeroImage = true;
});
};
// if the user scrolled down, let's first scroll all up before closing the stack.
var scrolled = scrollY();
if( scrolled > 0 ) {
smooth_scroll_to(isFirefox ? docElem : bodyEl || docElem, 0, 500).then(function() {
closeStack();
});
}
else {
closeStack();
}
}
else if( canOpen ) { // stack is closed
canMoveHeroImage = false;
classie.add(bodyEl, 'view-full');
setTimeout(function() { classie.add(bodyEl, 'move-items'); }, 25);
bodyEl.style.height = stack.offsetHeight + 'px';
flkty.unbindDrag();
flkty.options.accessibility = false;
}
}
else if( classie.has(stack, 'stack-prev') ) {
flkty.previous(true);
}
else if( classie.has(stack, 'stack-next') ) {
flkty.next(true);
}
});
titleEl.addEventListener('mouseenter', function(ev) {
if( classie.has(stack, 'is-selected') ) {
canMoveHeroImage = false;
imghero.style.WebkitTransform = 'perspective(1000px) translate3d(0,0,0) rotate3d(1,1,1,0deg)';

}
});
titleEl.addEventListener('mouseleave', function(ev) {
// if current stack and it's not opened..
if( classie.has(stack, 'is-selected') && !classie.has(bodyEl, 'view-full') ) {
canMoveHeroImage = true;
}
});
});
window.addEventListener('mousemove', throttle(function(ev) {
if( !canMoveHeroImage ) return false;
var xVal = -1/(win.height/2)*ev.clientY + 1,

imghero.style.transform = 'perspective(1000px) translate3d(' + transX + 'px,' + transY + 'px,' + transZ + 'px) rotate3d(' + xVal + ',' + yVal + ',0,2deg)';
}, 100));
// window resize
window.addEventListener( 'resize', throttle(function(ev) {
// recalculate window width/height
win = { width: window.innerWidth, height: window.innerHeight };
// reset body height if stack is opened
if( classie.has(bodyEl, 'view-full') ) { // stack is opened
bodyEl.style.height = stacks[flkty.selectedIndex].offsetHeight + 'px';
}
}, 50));
// Flickity events:
flkty.on('cellSelect', function() {
canOpen = false;
classie.remove(bodyEl, 'item-clickable');
var prevStack = stacksWrapper.querySelector('.stack-prev'),
nextStack = stacksWrapper.querySelector('.stack-next'),
selidx = flkty.selectedIndex,
cellsCount = flkty.cells.length,
previdx = selidx > 0 ? selidx - 1 : cellsCount - 1;
nextidx = selidx < cellsCount - 1 ? selidx + 1 : 0;
if( prevStack ) {
classie.remove(prevStack, 'stack-prev');
}
