Adding Text Under a Button

Hi everyone,

My site is using the Lawyer Zone theme which allows one button at the top right of the menu. I’m trying to add more text below the button itself (trying to add an address) but the theme itself does not have that option. I’ve added the below CSS, but it puts it right after the phone number. Is there any code I could put in that move it down below the phone number?

.desktop-only a:after{
content: “Address Goes Here”
}
