How do I reduce the image size for full width images on mobile, so that they don't get cropped off?

HI, 

I wonder if anyone can help me out. I'm revamping our website and have some large full width images on multiple pages (Home page and landing pages). I'd like to reduce the size of the images for Mobile view to prevent them being cut off. 

I've reviewed previous suggestions/advice here but haven't found anything that works for me. 

I've installed an app that allows me to view squarespace block, image and section id's. However I still can't get it to display correctly. Here is an example of the code I've used (I've tried many more combinations):

Attached is a couple of images 1. the desktop v 2. the mobile.


 

Can you share link to homepage/landing pages? /config is url for site owner

Absolutely, I wasn't quite sure of the best way to do that so I password protected it and can share the password with you: MHTest123

You are a legend! That worked exactly as I would have hoped. I will take that and resize the rest of my landing pages. 

I truly appreciate your help, thank you!
