In order to make it compatible for smartphones from Business Catalyst you will have to design the pages or template for smartphones. Business Catalyst simply lets you design the templates for mobile devices separately.

Also, that will not be backwards compatible with Muse. So, next time you publish through Muse, changes will be gone and you will have to make the changes again.
