What are the best image sizes for the Google Chrome mobile website audit?
I'm making a WordPress website and want to get the best score possible. There will be an image with 100% width on the top page. I just need to find out what sizes Google wants it to be now.
add_image_size( 'iphone-320', '320', '9999', false );
I'm going to add some code like this to the functions.php file of the template.
