CSS: Positioning a child element relative to its parent using any position property on the parent

<div style="width: 300px; height: 300px;">
   <p>Position me relative to my parent.</p>
</div>

In the above HTML, let’s say I want that p element to go to the bottom of the parent div. It’s common to use the following CSS:

div {
   position: relative;
}

p {
   position: absolute;
   bottom: 0;
}

My question is: Could I also achieve this by using any position declaration(other than static) for the parent?

I’ve been trying to find concrete proof of this but the CSS spec is inaccessible(won’t load) and various reference sites like MDN and w3schools say "An element with position: absolute; is positioned relative to the nearest positioned ancestor," which is a little vague.

In my tests, it seems that any ancestor that has a position other than the default of static can work for setting the child relative to.

Hoping to hear from someone who knows for sure on this. References from authoritative sources are greatly appreciated.

The question is:

static) for the parent?

Yes

From MDN:

A positioned element is an element whose computed position value is
either relative, absolute, fixed, or sticky. (In other words, it’s
anything except static.)
