我使用 Codrops 文章/实验创建了一个交互式环境，供当地团体在他们的会议上使用。这样做的问题是默认交互不是很直观。该模板使用 Flickity.js 和看起来像 classie.js 的东西来创建这个我遇到问题的滑动界面。
该页面可以在这里找到：
问题：激活全视图的唯一方法是单击 html 元素：
<h2 class=".stack-title">
// 堆栈激活后，您应该能够通过单击第一个 .stack-item 来激活完整视图，该 .stack-item 用于在其下方创建缩略图。这整个 div 应该是可点击的。用户在屏幕上到处触摸，而不是实际单击所需操作的标题。我希望这是有道理的。
换句话说，您应该能够单击堆栈标题和每个堆栈标题下方的图像，以将堆栈拉入屏幕上的完整视图模式。然后单击 x 或屏幕上的任何其他位置以关闭完整视图。
以下位于 main.js 和我找到的用于创建我所指的事件的参考。
//
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(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() {
