I am trying to use simple HTML in the Wiki Markup used to configure the header in the Documentation theme. I am being guided by the Wikipedia article:
https://en.wikipedia.org/wiki/Help:HTML_in_wikitext
which suggests that this should be possible.
As a simple example, I have this code in the configure header edit box:
<div class="center" style="width: auto; margin-left: auto; margin-right: auto;">Research & Strategy</div>
This is just being rendered as-is as the header of my Confluence pages - it is not being processed as HTML.
Thanks for any help you can provide!
