Hi Mariuse,
I’ve just had a look at the Spacious theme documentation page (https://themegrill.com/themes/spacious/) and if you have the free version of this theme, then there’s no option to change fonts out of the box.
If you upgrade from free to pro version, then there’s a user-friendly option to add Google fonts. The latter are so many that you most certainly will find a type that suits your language requirements.
Alternatively, if you stick with the free version, your theme offers a custom CSS editor which allows you to change fonts manually using CSS rules. Adding something like this to this CSS editor would change the basic font used on the theme:
body {
font-family: Arial, Verdana, sans-serif;
}
Also, if this rule isn’t being applied everywhere it means that in the theme’s stylesheet there must be a more specific rule that applies to a specific area of your theme that affects the font-family. In this case, it’d be really helpful if you could post a link to the page where you want to apply the modification. This way, the HTML elements can be targeted with precision.
I hope this helps ??
