Where to modify what sizes of Webfonts are loaded?

Hi @ichmusshierweg;
I’ve found the answer in Enfold Documentation :

add_filter( 'avf_google_heading_font', 'avia_add_heading_font');
function avia_add_heading_font($fonts)
{
$fonts['Raleway'] = 'Raleway:200,300,400,600';
return $fonts;
}

add_filter( 'avf_google_content_font', 'avia_add_content_font');
function avia_add_content_font($fonts)
{
$fonts['Raleway'] = 'Raleway:200,300,400,600';
return $fonts;
}
