Virtue sitewide banner shows only on mobile

Hello,

I use the Virtue theme, which is really great, by the way.
However, I have a problem with the sitewide banner.
I use the following CSS:

.home .virtue_banner {display:none;}

to remove the sitewide banner from home page, but it still appears on mobile devices (on small screens).
What can I do to remove the sitewide banner from all pages, but ONLY in mobile view (on small screens) ?

The site is https://www.boutiquemed.ro/boutiquemed.ro

Thank you,
