I have a QTextEdit where I do display some HTML. Could I apply a stylesheet to that very HTML content?

Do not confuse it with applying a Qt stylesheet to the QTextEdit (that I know). I want to change the appearance of what is in the QTextEdit widget ("HTML").

You can have a look at Qt ignores CSS in QTextDocument which uses QTextDocument and the defaultStyleSheet property / setDefaultStyleSheet() http://doc.qt.io/qt-5/qtextdocument.html#defaultStyleSheet-prop

Note that QTextEdit only supports the following html subset http://doc.qt.io/qt-5/richtext-html-subset.html if you want to do more then that you are probably best of using the QWebkit or QWebEngine modules depending on which Qt version your targeting.

As per Qt5, many CSS properties are supported:

The following table lists the CSS properties supported by Qt's rich text engine.

The best way to apply them is to start your document with <style> and use classes. However the <node style=""> attribute also works.
