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 css. Ie, I want to use absolute positioning with the two child divs, but position them relative to the parent div rather than the page. How can I do this?

Sample html:

<div id="father">    <div id="son1"></div>    <div id="son2"></div> </div> 

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.
