I have looked all over message boards and put in code but nothing seems to work. The image banner works perfectly on the desktop but doesn’t resize for the mobile site.
You have a widescreen picture that is not suitable for the mobile version. If you change the css background-size: contain property, the picture becomes smaller, but it fits under the screen size.
We recommend using a different version of the image that is more suitable for the mobile version of the site. Edit the text in the image and adjust the size.
To be honest, this does not help much. We have tried multiple different image resolutions that Shopify recommends and the image is still cut off on mobile. We were hoping for more of an in-depth response on how we would go into the coding and resize the image for solely the mobile site.
This is, unfortunately, a common issue with all free themes in Shopify. This can be a potential quick solution to avoid digging into coding and/or hiring a developer.
