Make Logo Image Stretch In Menu 100%

Hello,

Is it possible for me to make the Logo image stretch 100% on mobile devices. I am able to set a Logo width under logo options but would really like to have the logo image just stretch 100% in width on all mobile devices if possible just not sure if CSS could make this happen or another setting?

Thanks N Advance
