When implementing UI components that show text, you might've asked yourself the question: How do I set font sizes? The answer is, of course: It depends :-).

But what does font size depend on? It can be specific to the component - is the font used as a title, or just a little foot note label? Critically though, the size might also depend on other text in the application, and font size needs to be consistent with sizes used in other components.

The latest Slint release includes a new unit for relative font sizes: the rem unit that works like CSS and provides a scale factor that resolves relative to the root font size. In Slint this base is the default-font-size property of the root Window element.

You can now write:

Text {
    text: "Hello";
    font-size: 1.5rem;
}

and the font size will 1.5 times of the current value of `Window.default-font-size`. If `default-font-size` changes, the label's text will of course get re-rendered automatically.
