Thank you for your question!
The responsiveness of many website areas in our themes, like the header and footer sections, are automatically designed to shift their content to create a readable mobile display. There are also some Responsive Utilities provided by the Post and Page Builder that allow you to select the device type and change how your content looks for difference screen sizes.
I hope that helps you configure your content as expected and please let us know if there is anything else that we can do to help.
