Describe your issue

The fixed utility is beheaving as absolute when present as a descendant of an element with @container class. It's seems an issue with "container-type: inline-size;" rule.

Hey! It looks like this is just how this behaves in CSS I'm afraid — can see the same behavior here with totally vanilla CSS and no Tailwind at all:

So not much we can really do here, at the end of the day Tailwind is just a bunch of classes setting CSS properties so what those properties do in CSS is what they are going to do in Tailwind.

Here's a relevant Stack Overflow question that talks about this behavior:
