Hello, I also want to know

You can override the original style

app = QApplication(sys.argv)
apply_stylesheet(app, "dark_teal.xml")
stylesheet = app.styleSheet()
with open('custom.css') as file:
    app.setStyleSheet(stylesheet + file.read().format(**os.environ))

custom.css

QGroupBox {{ text-transform: none; margin: 0px; padding: 20px 0px 10px 0px; }} QPushButton {{ text-transform: none; }}
