Block in custom section - Dawn

[Blurrr]

Hi I am having some trouble with a custom section so I've added a section using the code on this forum

https://community.shopify.com/c/shopify-design/how-do-i-add-an-email-signup-to-image-banner-on-dawn/...

It works fine on Desktop and displays as it should. However on mobile it puts the email form underneath the image and not as an overlay like in desktop mode. I can't seem to figure out how to fix this please can someone help?

Is this how you want it to show?
You have to play around with some css properties using position absolute on section-image-banner.css file in theme.
