I have markup that looks like this
<div>
<h1 style="text-align:center;" >Heading 1</h1>
<img style="float:left;" src="logo.gif"/>
<h1 style="text-align:center;" >Heading 2</h1>
</div>
<div>
Content goes here
</div>
The problem is that heading 2 is centered relative to the remainder of space after the image, and not to the whole div, so its not centered on the page.
If I remove the img from the flow with position:absolute, it does not push down the content and instead overlaps it.
Solved it through trial and error. I don’t know why but in my testing it only works if width is set between 12 and 80%.
So it seems “h1” is a block element, and text-align does not center block elements, it only centers inline elements inside it, which explains the “centered off-center” behavior. So it turns out the answer is the same answer to the question “how do you center a block element?”
