Can I remove the guide footer for mobile devices only?

Hi @Melody Quinn,  you can use media query for this. 

@media (max-width: 480px){

.footer {  display: none }

}

the class footer can be different of your theme so you can change it i.e., footer-wrapper, main-footer, etc.. I'm using default Copenhagen so I fiund footer class name.
