But if there’s one thing I like, it’s a challenge. This means we always have a struggle between the horizontality of presentations and the verticality of web technologies. Presentations are a very horizontal thing – usually slides have a 4:3 or 16:9 radius. That’s too bad, as at the company I work for this would be quite useful. Unfortunately, that’s not going to happen. I’d be nice if we could do something like this: /* This isn't real */ But sometimes, you want to step away from the verticality of it all and do something crazy: make a horizontal list. You read a web site like you read a physical page: left to right, top to bottom. Please show your love and support by sharing this post.The web is a rather vertical place.

So, if the parent has align-items: normal (which is the default) or align-items: stretch set, then it means the height of the sticky element would stretch to fill the entire available space. In this case the value of align-self would compute to the parent's align-items value. If the Sticky Element Has align-self: auto Set: The sticky element has align-self: stretch set.The sticky element has align-self: auto set (which is the default).If sticky element's parent is a flexbox, there are two scenarios to check for: This happens because the sticky element is meant to stick/scroll within the height of a containing element.Ĭhecking if a Parent Element Is a Flexbox If the parent element has no height set then the sticky element won't have any area to stick to when scrolling. How to Make position: sticky Work With the overflow Property?īy specifying a height on the overflowing container, you should be able to make position: sticky work whilst having the container element have the overflow property set.Ĭhecking if height Property Is Not Set on Parent Let parent = document.querySelector('.sticky').parentElement Ĭonst hasOverflow = getComputedStyle(parent).overflow Simply copy/paste the following snippet in your browser's web developer console to identify all parent/ancestor elements with overflow property set to something other than visible: Snippet to Check for Parents With overflow Property Set: If any parent/ancestor of the sticky element has any of the following overflow properties set, position: sticky won't work ( unless you specify a height on the overflowing container): Make sure you add a vendor prefix for the property value to support versions of Safari below 13, for example, like so:Ĭhecking if an Ancestor Element Has overflow Property Set
