Body { Overflow-X: Hidden; } Breaks Position: Sticky

Position sticky not working with body{ overflow-x: hidden; }

As far as I know, you cannot use it by now.
It is still only partially supported in some browsers.

When you want to know how far it is with this feature, I can advise you to check it on caniuse.com.

CSS position: sticky and overflow

It's important to understand that sticky elements are first treated like a relative element and then a fixed element (see MDN). Therefore, you must first look at it like a relative element. If you give a height of 100% to a relative element, then nothing really happens unless its parent element has a defined height.

If you want your sticky element to have a scrollbar too, you must give it a meaningful height. I suggest using viewport height:

.child {
  position: sticky;
  top: 0;
  bottom: 0;
  height: 50vh;
  overflow-y: auto;
}

For the record - the "stickiness" doesn't appear to be working as expected in either FF or Safari in terms of the element becoming fixed during scrolling. I'm not concerning myself with that - just focusing on the overflow issue.

Why position sticky is not working in my code?

Its because you have overflow-x-hidden in parent . sticky doesn't work if parent overflow is hidden.

Overflow-x:hidden doesn't prevent content from overflowing in mobile browsers

Creating a site wrapper div inside the <body> and applying the overflow-x:hidden to the wrapper instead of the <body> or <html> fixed the issue.

It appears that browsers that parse the <meta name="viewport"> tag simply ignore overflow attributes on the html and body tags.

Note: You may also need to add position: relative to the wrapper div.
