Combine Font API Calls In Child Theme Issu

Hi,

I’m running a child theme and I want to combine three of the Google fonts from the parent into one api call. I think I figured out the code for that (below).

I ran it through GTMetrix and it calls it, but it also continues to call them separately. I tried the wp_dequeue_style. It worked on a different font, but not these three.

Plus, not only am I seeing them being called through fonts.googleapis, but again at fonts.gstatic.com in GTMetrix, though not on the page that I see. Why would that be? A plugin calling it? I couldn’t find the gstatic version in the parent’s function.php.

Any ideas would be greatly appreciated. Thanks.

Combining all three:

function prefix_fonts() {

    wp_enqueue_style( 'prefix_fonts', '//fonts.googleapis.com/css?family=Open+Sans:400,600,700|Lato|Roboto+Slab:400,700', array(), null, 'screen' );
}
add_action( 'wp_enqueue_scripts', 'prefix_fonts' );

Code I used to try to dequeue (worked on Droid Arabic Kufi):

‘function remove_default_stylesheet() {
wp_dequeue_style( ‘droidarabickufi’ );
wp_dequeue_style( ‘lato’ );
wp_dequeue_style( ‘roboto-slab’ );
wp_dequeue_style( ‘open-sans’ );
}
add_action( ‘wp_enqueue_scripts’, ‘remove_default_stylesheet’, 11 );’
