Side by side buttons for mobile and desktop. Not stacked

Site URL: https://thebookofspir.com

Hey, I'm having trouble getting all three buttons to be side by side. I would like music, feel, and merch to all be side by side but it always stacks when switching to mobile view. Help with some custom CSS would be greatly appreciated.

/* Music Feel Merch mobile */

    width: 33.3333% !important;
    float: left !important;
}}
