There's something thats been puzzling me for a while and I cant really figure out a proper solution!

say I have a div with properties something like the following:

width:200px;
height:300px;

and I make another div something like:

width:200px;
height:50px;

What would I do if I wanted the second div to always be at the bottom of the containing div? even If I were to alter the containing div's attributes so that it was even taller.

I have a feeling its something to do with positioning [and setting the 'bottom' attribute], but Im not sure which positioning I should go for as none of them seem right!

You're right. It involves positioning and the bottom property. This is easy to do, but there's more than one way to achieve this, which depends on how you set up your layout.

If you want the container div to stay in the normal flow of the page or have it's presence known by the surrounding elements, then you'll want to add on the outer div: position:relative;. Then on the inner div: position:absolute;left:0;bottom:0.

The other way is the same except you'd change the outer div from position:relative to position:absolute, and then the top and left to the actual position you want it from it's parent container which will be the whole window if it's not inside any other positioned parent. Which means it has to have a position explicitly applied to it other than the default static position.

If you used position:absolute to position lots of elements in your layout then you'd most likely want to go with the second solution, otherwise you'd probably want to go with the first one.

Ahhh I get ya, thanks!

No problem buddy.

Also if you're using a div container just to apply a positioning context for it's child elements, then you don't have to set a top:, left: etc. for it. you could just have on the container div: position:relative or position: absolute only.

You'd only want to set a top:, left: etc on the parent div if you're wanting to position it somewhere different from it's normal flow as well.

I edited my first post after realizing that I had extra pointless code in it.
