Sitetitle style not loading on iPhone

[alexandrap]

I put a CSS style
.sitetitle img{
-webkit-box-shadow: none;
-moz-box-shadow: none;
box-shadow: none;
}

in both desktop and mobile css fields, but for some reason it's working on the desktop version, but not on the mobile version, the site title still has a drop shadow.

Thanks!

ok, well you can debug this by using the inspector and resizing your browser so it has the phone size.
