I understand you're looking to adjust the height for the banner on the mobile view of your Brooklyn theme. Since you're using a Shopify-supported theme, then this may be something that our Theme Support team can help you with. If your store is subscribed to a plan, you're eligible to use the complimentary design time included with your subscription on customizing your theme. While we’re not able to provide account-specific support via the Shopify Community at this time, we’d be happy to continue assisting you through live chat, email, or callback. Please visit the Shopify Help Center and log in to your account to create a support request.
