How to fix position sticky not working?

“Position sticky” is a gem in the CSS library that allows an element to be sticky — allowing it to stay in place, or “stick”, while the page is scrolled. However, it’s not uncommon to have bouts with its unresponsiveness or outright refusal to work. There might be several reasons why you’re experiencing difficulty with position sticky. Below we’ll uncover the mysteries of this feature, explore possible challenges you might face, and offer solutions to get it working smoothly once again.

Understanding Position Sticky

CSS’s position property defines how an element is positioned on a page. The “sticky” keyword means that the element will move with the page scroll until it reaches a defined point, and then it will ‘stick’ in place. The sticky behavior allows the position of the element to vary between relative and fixed, depending on the scroll position.

Common Issues and Fixes

Issue #1: Parent With Overflow Property

One common mistake is using a parent element with an overflow property set to anything other than “visible.” The overflow property specifies what should happen when content overflows an element’s box. If it’s not set to visible, position sticky may not work.

Fix: Remove the overflow property or set it to visible on the parent container.

Issue #2: Missing Offsetting Value

Another common issue is forgetting to add an offsetting value with CSS’s top, right, bottom, or left properties.

Fix: Add an offset value. This inform the browser at what point one would like the element to stick.

Issue #3: Not Enough Scrollable Area

CSS’s position sticky needs room to work. If there isn’t enough scrolling space in the parent container, the element simply won’t stick.

Fix: Ensure that the parent container or the page has enough content that can be scrolled.

Issue #4: Using Z-Index Improperly or Not At All

CSS’s z-index property controls the vertical stacking order of elements; elements with higher z-index values are “closer” to the viewer. If not used properly, position sticky could fail to render as expected.

Fix: Apply an appropriate z-index value without disturbing the stack order to avoid overlapping of elements.

Browser Compatibility

Compatibility is a crucial aspect of web development. Your codes might be flawless, but if the target browser does not support CSS’s position sticky, it’s likely not to work. As of 2021, position:sticky; is supported in most major browsers like Chrome, Firefox, Safari, and Edge. But some older versions or less-used browsers may not extend support for it.

Fix: Ensure that your target audience is likely using a browser supporting this property.

Wrapping Up With Some Tips

CSS’s position sticky is a powerful tool for creating more advanced layouts and enhancing user experience on websites, but its functionality can be hampered by various factors. Doing a thorough check and testing different resolutions can help you determine if a property of a parent element is hindering its performance or it’s a browser compatibility issue. Let’s remember that in web development, understanding the intricacies of even the smallest features can ease our way towards building a perfect website.
