PyQt5 - Can I use different font sizes on different parts of the text in a label?

I would like to have a label where I have text with parts where the sizes are different. Is this possible with PyQt5 or some CSS?

PS: I haven't coded it and am more looking for the theoretical answer than code so I can't provide any code or such.

Solution

  • QLabel supports a limited HTML subset, and basic styling is still enabled:

    self.label.setText('''
    normalText 
    <span style="font-size: 18px">biggerText</span>
    <span style="font-size: 24px">veryBigText</span>
''')
