centering a div between one that's floated right and one that's floated left
I have a page in which a header consists of three divs - one that's floated to the left, one that's floated to the right, and one that's in between them. I'd like for that central div to be centered, yet sadly float: center doesn't exist and I can't just float it to the left and add padding as it'd have to change depending on the window size.
Is there something simple I'm overlooking? Or how would I do such a thing?
Update:
In addition, I'd like to find a way of centering that middle div in the space between the divs in case that looks better.
Answer
If you have two floated divs, then you know the margins. The problem is that the float:right div should be put before the middle div. So basically you will have:
left-floated | right-floated | centered
Now, about the margins: usually you can just use margin:0 auto, right? The problem is that right now you know the values of the margins: floated divs! So you just need to use:
margin:0 right-floated-width 0 left-floated-width
That should work.

Meanwhile, a new toy is in town: flexbox. The support is fairly good (i.e. if you don't need to support lower than IE 10) and the ease of use is way over floats.
You can see a very good flexbox guide here. The example you need is right here.
