using google fonts

Hi,

I would like to use a specific Google font, which is not in the drop down list of Enfold. I want to use it for main content, headings and the menu. I’ve tried to use this code (at General Styling >> Fonts >> Quick CSS) but the font is still not visible at the drop down font list.

add_filter( ‘avf_google_heading_font’, ‘avia_add_heading_font’);
function avia_add_heading_font($fonts)
{
$fonts[‘Alef’] = ‘Alef’;
$fonts[‘Futura’] = ‘Futura’;
return $fonts;
}

add_filter( ‘avf_google_content_font’, ‘avia_add_content_font’);
function avia_add_content_font($fonts)
{
$fonts[‘Alef’] = ‘Alef’;
$fonts[‘Futura’] = ‘Futura’;
return $fonts;
}

Kind regards,
Marca van den Broek
