Hi Umairee95,
thanks for using MH Magazine lite.
Changing fonts isn’t possible in the free theme out of the box. However, if you’re familiar with coding, you could of course create a custom child theme and include different fonts based on your personal needs and requirements.
I inspected one of my posts but could not find what element is controlling my font.
You can inspect the <body> element on your site and there you’ll find the CSS related to the default font that is set for the theme.
Also, I can’t find quotes’ settings. How can I change its font size or select a different font for that?
There is no setting for quotes. If you want to style quotes differently, you can code this as well as you like. There are plenty of tutorials available online, for example here.
And here you can learn more about adding fonts as well: Implementing additional fonts for your WordPress website.
