I want to set smaller margin before fancy heading after horizontal rule. This fancy heading is first in "add item" container, paddings are set to 0.
In firebug I see:
<hr class style="margin: 0 auto 55px;">
I think I should change this margin but I don't know how.
please send us url to page where you got this fancy heading item and we'll see why got got such a large margin and where comes from.
As we see you are using Divider Item in Muffin Builder.
Please edit this page, scroll to Muffin Builder, find Divider item, click Edit button and change Divider height attribute
