Sticky element is larger than its container, cannot create s

Error message

Sticky element is larger than its container, cannot create sticky.

What it means

Emitted by Sticky's checkErrors() (sticky.js:163-165) when module.cache.element.height > module.cache.context.height — the sticky element is taller than its container/context. There is no room for it to travel while scrolling, so Sticky calls module.reset() and aborts stickiness. It is a console.error (sticky.js:776), not thrown.

Solutions

1. Shorten the element's content or let it scroll internally so it fits within the context.
2. Choose a taller context element via settings.context.
3. Call $('.sticky').sticky('refresh') after images/content finish loading so heights are recomputed.
4. Reconsider whether sticky positioning is appropriate for that element.

Example fix

// before
$('.tall-ad').sticky(); // ad taller than its context -> sticky disabled
// after
$(window).on('load', function(){
  $('.tall-ad').sticky('refresh'); // recompute after images load
});

// Verify the element is shorter than its context before initializing.
function safeSticky($el, $ctx){
  if ($el.outerHeight() > $ctx.outerHeight()) {
    console.warn('Element taller than context; sticky disabled by design.');
    return;
  }
  $el.sticky({ context: $ctx });
}
// call after layout settles:
$(window).on('load', function(){ $('.sticky').sticky('refresh'); });

When it happens

Trigger: A sticky element whose rendered height exceeds the context height — e.g. a tall sidebar or large ad inside a short context — at the moment checkErrors runs.

Common situations: Responsive layouts where content collapses into a tall narrow column, late-loading images/ads inflating element height after init, very short context (small banner area).
