Mobile logo – Responsive size

Hi There,

I’ve got a responsive pb with my mobile logo I’ve read in the support topic that I need to add in the css box the following piece of code

@media only screen and (min-width: 200px) and (max-width: 670px) div.logo-box img { display: block; width: 40%!important; margin: 0 auto; height: auto; }

but unfortunately whe I check my mobile maintenance page the logo is still very big, can you help me?

thanks
