title: fix header on mobile version
body: <p>at our site www.ftina-pc.gr (prestashop based) I need to align the mobile menu with the logo. 
  I have tried float etc but can't find a way to fix this. 
  The desktop version is OK. only the mobile version has the problem. 
  I have attached a mockup on how it should look. 
  Can anyone please help me ?</p>
