Cross-tech UI: HTML5 and QT support?

Question

JavaScript

Dear QT and HTML5 Experts,
There is a need for a cross-platform user interface for a complex Python desktop application. QT and HTML5 are equally suitable for this (via Cromium Embedded Framework / system browser). There are disjoint sets of QT and HTML5 developers, and both technologies need to be supported at some stage (until everyone is retrained and a choice has not yet been made in favor of one or the other). Thus, the question arises, is there a layer technology (templater / declarative schema) that allows you to create a user interface simultaneously under QT and HTML5?
Otherwise, it can be formulated as follows: how “friendly” are HTML5 and QT?

Cross-tech UI: HTML5 and QT support

To begin with, I can not recommend you to look here: how to convert QuickTime to HTML5 for website
While everyone is relearning, you can read this Qt5 + HTML5
topic. Finally, when the choice is made in favor of Qt, you need to choose what is preferable for you - use widgets and the magic of QSS or QML, coupled with Quick Controls
Personally, I would choose QML, especially since writing a qml <-> css translator of average complexity should not be difficult.
There is another interesting, but apparently rotten project: qmlweb

Answer 2

You can create html applications on Qt. That is, an application is actually created, where the engine is inside (QtWebkit, most likely), and it can certainly be reconfigured.
