I'm not sure that it's a better solution to get editors to make edit notices in uneditable HTML boxes, rather than the padding be system-level. The padding is designed to take normal edit notices; if you make fancy ones that break, the onus is generally on you. :-)

Note that we're planning on having setting/editing/removing page-level edit notices built into VisualEditor in the next few months, which will make enwiki's solution available to all wikis.

Hi James,

I don't know what mean you by normal edit notices :) A simple 100% div, with background color but without padding would look weird inside the flyout.
We are rethinking the editnotices design/content and right now they look somewhat awkward within this asymmetrical padding. If someone ever need a margin it can be done within the editnotices itself, but this mandatory padding limits the design a lot.

Normal edit notices are text only (or bold/italics/links). Adding any further styling, including <span>s, <div>s, images, etc. is likely to break in a variety of situations and isn't really intended behaviour for the tool.
