Ok so I managed to import the html by modeling my code similar to the example with: QString code = QStringLiteral("qt.jQuery('#first_page').load('html/first_page.html');"); //you can even nest it with: QString code = QStringLiteral( "qt.jQuery('#first_page').load('html/first_page.html', ()=>{" "qt.jQuery('#border_content').load('html/border_content.html', ()=>{" //some other html "qt.jQuery('#last_page').load('html/last_page.html');" "});" "});" ); unfortunately I now cannot use the qwebchannel.js script anymore and my css gets screwed :( even loading it with: QFile script_file(":/qtwebchannel/qwebchannel.js"); if(!script_file.open(QIODevice::ReadOnly)) qDebug()<<"Couldn't load Qt's QWebChannel API!"; QString qt_script = QString::fromLatin1(script_file.readAll()); script_file.close(); view->page()->runJavaScript(qt_script); did not help. Since it is a small project and I am on a short deadline right now I will put everything in one html file and mark this question als solved.

@mpergand you are right, this line solved the problem. Thank you very much!
