Hi Frank,

Usually the setup is that the CMS links to the CSS from the HTML. That is, the page
Delivered to the web browser contains lines like 

  <link rel="stylesheet" href="/components/com_jcomments/tpl/default/style.css?v=21" type="text/css" />
  <link rel="stylesheet" href="/cache/template/gzip.php?widgetkit-e2f1f3d7-9b14bd45.css" type="text/css" />
This is actually from view-source:http://www.nukepedia.com/gizmos/filter/efibonacciglow. The web browser will then automatically try to download and apply e.g. http://www.nukepedia.com/components/com_jcomments/tpl/default/style.css?v=21 . 

I understand that either your CMS is configured wrong, and doesn't include these links, or that you hit a bug in WebEngine where the css for a reason or the other is not fetched, or applied correctly. Can you clarify??

See above - it is something that the .html page itself should link to. The QWebEngineSettings::setUserStyleSheetUrl you found is only a fallback, e.g. if you want to tweak the layout of pages you don't have any control over on the server side.

As I mentioned already, you can also link from a CSS to another CSS by using the @import rule .
