Change heading font using WP Google Fonts

Hi , can sparkling change the header font without uploading logo ?
I’m using WP Google font to change the header font

Thank You

Yes, if you already have this font linked to your WordPress website then there is nothing that will hold you back to use it for website title as well.

This is the CSS code to change fonts, I added Helvetica there, so you know what to change.

.navbar > .container .navbar-brand {
    font-family: Helvetica;
}

Unfortunately, this code won’t work via Theme Options - Other - Custom CSS because of specifics of this code but you can add it via Child Theme style.css or via Jetpack Custom CSS.

Thank you , without WP Google font I still can change the font using Google Font CSS script
