You may be seeing a difference between the different view ports (desktop/tablet/mobile) when viewing your site banner. Don’t worry this is not a bug, this is normal when our top banners are set up. The reason why its cutting off areas of the background image is to prevent the image ratio from scaling when reaching those view ports. This can cause display issues especially when the editable content (text, button & etc) is overlayed on top of the background image. It was set up this way to accommodate the proper display of the banner & ensure that its responsive with our layout.
All images are designed differently or some photos are taken at a different perspective. Unfortunately we don’t accommodate for all these types of images.
If this does not work for you and want to fit the background image to the whole screen on mobile/tablet or modify how the banner is displayed, then you will need to adjust both the HTML & Custom CSS including the media queries to fully customise your experience. You can do this by switching to the HTML Block for the banner. Refer to this blog post regarding HTML Editors on the site: https://www.thrinacia.com/blog/post/how-to-add-custom-code-to-a-section-of-the-site-through-the-html-editor The other option is to update your uploaded image that will best fit this setting.
