I have added the Typekit plugin and set up CSS rules for most of the font types for my site, but can't determine the correct css name for "Navigation Font", "Navigation Dropdown Font", "Page Heading Font" and "Page Heading Subtitle Font". Can you tell me what those are so I can set up the CSS rules? Thank you.

That makes sense, but I am not sure how to address adding multiple fonts. Would I do it this way:

function salient_redux_custom_fonts( $custom_fonts ) {
    return array(
        'Typekit Fonts' => array(
             'coquette,sans-serif' => "Coquette"
 'proxima-nova,sans-serif' => "Proxima Nova"
  'felt-tip-woman,sans-serif' => "Felt Tip Woman"
        )
    );
}
add_filter( "redux/salient_redux/field/typography/custom_fonts", "salient_redux_custom_fonts" );

OR THIS

function salient_redux_custom_fonts( $custom_fonts ) {
    return array(
        'Typekit Fonts' => array(
             'coquette,sans-serif' => "Coquette"
        )
'Typekit Fonts' => array(
'proxima-nova,sans-serif' => "Proxima Nova"
    )
'Typekit Fonts' => array(
  'felt-tip-woman,sans-serif' => "Felt Tip Woman"
  )
    );
}
add_filter( "redux/salient_redux/field/typography/custom_fonts", "salient_redux_custom_fonts" );

Or do I need to enter the entire code for each font? I tried a few different ways and none seem to work.

Thanks!
