uses a responsive design (bootstrap). the hero image is not showing up on mobile devices, which is good.
validator.w3.org/mobile/¿ says that the mobile page is nearly 500kb large, so it gives me a critical error. Google is telling me its much better than what validator says for mobile phones.
I was hoping that a mobile device would not actually load the hero image (which is 400kb). But the mobile checker at validator.w3.org is saying it does. is this true, and if so, anything I can do to change that? Ideally, I want mobile phones not to load the hero image, since it doesn't display anyway.
