Email formatting: single/double spacing in text editor

[Anonymous]

Can some one please shed some light on what the "single space" vs "doublespace" choice in the email editor does?  Meaning, does one insert a <br> vs a <p> upon "enter" or "shift+enter"? 

I've somehow got some templates where the editibable sections are set one way and some that are the other and I'm very confused - especially about how to train others on my team so we have attractive, consistent looking emails.   Help!

Thanks Elliot, just to be clear, you mean the format of either the <div> or <p> tags can be changed with CSS, correct?  either inlien or at the template level? 

Thanks!

Double space uses the paragraph "<p>" HTML tag, that causes browsers to add a line break plus some space (leading) before and after each <p> element.

Single space uses the division "<div>" tags that cause browsers to place a line break before and after the <div> element.

The format of either of these can be changed with CSS.
