By default, GenerateBlocks uses the following media queries.
Desktop only: (min-width: 1025px)
Tablet + mobile: max-width: 1024px)
Tablet only: (max-width: 1024px) and (min-width: 768px)
Mobile: (max-width: 767px)
To change them, we can use a simple filter:
add_action( 'wp', function() {
add_filter( 'generateblocks_media_query', function( $query ) {
$query['desktop'] = '(min-width: 1025px)';
$query['tablet'] = '(max-width: 1024px)';
$query['tablet_only'] = '(max-width: 1024px) and (min-width: 768px)';
$query['mobile'] = '(max-width: 767px)';
return $query;
} );
}, 20 );
