I have added three new featured image sizes to my functions.php;
add_image_size( 'feature-large', 768, 9999 );
add_image_size( 'feature-medium', 500, 9999 );
add_image_size( 'feature-small', 480, 9999 );
I want to use featured-medium on screens that are wider than 768px, featured-large on screens below 768px and feature-small on screens below 480px.
at the moment I'm just using
<?php the_post_thumbnail('feature-medium'); ?>
I'm using a bootstrap grid that is why I want to use the feature-medium on larger screens.
Is this even possible? Does anyone have any ideas how to implement this in the easiest possible way?
I look forward to your answers/ideas.
