Mobile Widget too small

Hi- I am using your premium plugin for adding the “search for your domain name now” button onto my blog page. It works great on desktop, but I noticed that on mobile it is shrunken down to a size that isn’t workable. I tried recreating it with a small screen=2 in the hopes that it would wrap differently, but that didn’t work. Please let me know how I can make it occupy more of the screen on mobile.
Thanks!
Becky
