Eliminate white background from text in Blogger

Sometimes I copy and paste an article into blogger, it looks great before it's posted, but appears with strips of white behind the text when the article is posted. This may be avoided by pasting the copied text into "Notes" on a Windows PC and then recopying it. But, "Notes" will strip out pictures and links as well, which is a real pain. So here is another solution that may work out better: using a not so obvious "unformat" option in Blogger.
