Position absolute but relative to parent

Question

I have two divs inside another div, and I want to position one child div to the top right of the parent div, and the other child div to the bottom of the parent div using cs

Answer 1

#father {
   position: relative;
}

#son1 {
   position: absolute;
   top: 0;
}

#son2 {
   position: absolute;
   bottom: 0;
}

This works because position: absolute means something like "use top, right, bottom, left to position yourself in relation to the nearest ancestor who has position: absolute or position: relative."

So we make #father have position: relative, and the children have position: absolute, then use top and bottom to position the children.
