I'm sure this is an easy thing to do, but I just can't find it in the pageline settings nor in the CSS. How do I change the margins from the defaults established in pagelines? I want to make my left margin about 30px. I've tried to resize them via the layout editor, but this doesn't seem to do the trick.
I have a feeling that it's done via the layout editor by setting the global page width and then adjusting the content and sidebar areas to force the margins. However, I can't enter values into the boxes themselves - they are grayed out. I can only resize to make the width numbers change. (see screenshot)
(Side note: it would be great if margins could be added as an option to insert in the pageline configurations.)
