How does CSS work in font without italic?

This page is importing these fonts.

  • Roboto
  • Playfair Display
  • Playfair Display Italic

Think

When the first font I specify doesn’t have italic, will the first font be italicized or will the second font with italic be displayed?

Code

<span style="font-family: 'Roboto', 'Playfair Display'; font-style: italic;">
This is Roboto first, Playfair Display second. And style is italic.</span>

Execute

This is Roboto first, Playfair Display second. And style is italic.

Conclusion

Force italics when that doesn’t have italics, without displaying the next font.
