I thought I would share a solution to a particular problem I've had that others may find useful.
My email design called for an editable anchor link aligned to the bottom of a table. This worked fine, except when the item was repeated, and the CM editor wrapped the link with a <p> tag (as CM requires an editable link to be wrapped in a <multiline> tag).
Outlook.com ignored my attempts to set margin-bottom on the <p> to zero, so there was always an ugly gap under these links, breaking the design.
The solution I found was to add my own <p> tag around the link in the template, and set it to style="display: inline". The CM editor recognised that there was already a <p> so it left it alone!
The user is able to edit and change the link address, as long as they don't delete the link accidentally, thus removing the <p> set to display:inline.
No more gaps in Outlook!
