Thank you for reaching out to the Constant Contact Community. I’d be happy to assist you today.
I am sorry you are having issues with the alignment of your campaign. You mentioned the style sheet, so it sounds like you are still using our Second Generation Editor. If the campaign appears aligned to the right, it is sometimes caused by an image that is too large for the area it is inserted in to. That can cause the template to "stretch" and when in the preview window, you will sometimes have to scroll to the right to see the whole email. To alleviate that, find and resize the offending image.
If you would like us to take a look at it to verify the issue and help resolve it, please send an email to communitysupport(at)constantcontact(dot)com and include your username, the campaign you are having issues with, and a reference to this community post. Once we receive that email, we'll be able to do some additional troubleshooting for you!
