I have to switch in some projects to the custom phone layout. But there's no way to define the value of 'Frame Top' in pixel (like in Customize / Mobile Spaces)
I guess it's not easy to add pixel global for 'Frame Top' in the Lay Options / Phone Gridder Defaults. But Marius already mentioned in this thread to use Custom CSS, unfortunately I can't.
I already found something like this in the html:
<div id="custom-phone-grid" class="grid">
and in the css:
@media (max-width: 600px)
eg. for a project, how could the Custom CSS (for Mobile Version) look like with these attributes?
