Align middle both elements depending on which element stretches parent

#superb is element of flexible height.
#inner1 should be 100% allowable height of #superb (minus padding and own margin).
#inner2 should be expanding #superb, as big as it’s height + padding + margin is.

I need it to work in at least Internet Explorer 10.
Is it doable?

I think Flex would do the trick Flex

That would be solution, if not:

Which makes #inner2 pop to the left, without relation to flex and text-align: right… well… stretches the #inner1 all the way to the right.

This is why flexbox wasn’t my instant idea. Because it’s meant to be used for flexible layouts, not to fill contents.

In your example you are floating inner1 and inner2. That is not needed when using Flex. And I think you can use Flex for what you are looking for. Just read carefully through the documentation

Edit: otherwise you could try the display: table/table-cell approach

Hi there GooGit,

I thought that you wanted the left column to have a fixed width. :no_mouth:

If that is still your desire, then try it like this possible solution…

<html lang="en">

<meta charset="utf-8">

#container {
    display: flex;

    width: 80%;
    padding: 1em;
    margin: auto;
    box-sizing: border-box;
    background-color: #222;
