Hi, When i open my website on mobiles and tablets, i have some problems with some images that are not centralised. See bellow the description of each problem: Logo: My logo have white letters because when i open in a normal website, the banner pictures do the contrast, but when i open on mobile, the logo opens only with the white background and i can't see whats in it. Is possible to use two different logos, one for normal browser and one special for tablets and mobiles? Tap to call button: How can i change the collor of this button? I want it to be black. Menu: My menu bar is not centralised. I opened in iphone, in ipad and others gadgets and the menu is always on the left side. Is possible to change and put it on the center? Sample screenshot attached.
