I am using Twenty Twelve - child theme - and have a header image for the larger versions, but when it switches to mobile I am wanting either a small image or just text - instead of the large header being shrunken down. Any idea how to do this? I am still fairly new with coding, but have searched extensively and haven't quite found a solution for this. Basically, I want the default text only header to only show when minimized to a mobile device.
Thank you greatly in advance for any help!
Have a good day,
