I think this is a relatively common technique and it seems to me like it is fairly basic CSS.
I create a user manual in HTML (from a text file using asciidoctor) that uses the toc mode to create a table of contents which I then want to show as a left sidebar.
The html created appears correct (works with WebKit, WebEngine, or a regular browser), but litehtml (wrapped in qlitehtml) doesn't show the sidebar and instead shows the TOC before the main text of the page.

The key style in play here, I think, looks something like this:

#toc.toc2{margin-top:0!important;background:#f8f8f7;position:fixed;width:15em;left:0;top:0;border-right:1px solid #e7e7e9;
border-top-width:0!important;border-bottom-width:0!important;z-index:1000;padding:1.25em 1em;height:100%;overflow:auto}

this artifact shows you the full user manual in question, but if need be I can spend the time to trim this down to a much smaller document.

My question: is this something that litehtml shoud be able to do and I'm just doing it wrong? Or is this out of scope? Or is this a bug you'd consider fixing? And of course... how can I help?
