CSS Question

Vertically center rotated text with CSS

I have the following HTML:

<div class="outer">
<div class="inner rotate">Centered?</div>

is a narrow vertical strip.
is rotated 90 degrees. I would like the text "Centered?" to appear centered in its container div. I do not know the size of either div in advance.

This comes close: You can see from the jsfiddle that the text is vertically centered before the
transform: rotate(-90deg)
style is applied, but is somewhat offset after. This is particularly noticeable when
is short.

Is it possible to center this text vertically without knowing any of the sizes in advance? I haven't found any values of
that solve this problem.


The key is to set position top and left to 50% and then transformX and transformY to -50%.

.inner {
    position: absolute;
    top: 50%;
    left: 50%;

.rotate {  
    transform:  translateX(-50%) translateY(-50%) rotate(-90deg);
