Optimize Banner for mobile and desktop

[maurant]

Hi I'm having trouble with viewing my banner on my store. It doesn't fit on mobile or desktop. My theme is debutify. How can I go about fixing this?

store: dogstrom.co

looks like your first banner fits fine... most likely in your settings you forgot to add a mobile version

Hi it's the second banner when you scroll to the right.

looks like you will have to contact whoever did your theme
