Wacky

My blog is wacky. I can arrange my text a certain way, save it, and then it posts looking different than I intended. I don't know what's up. I've had two posts be in a paragraph forms rather than the way they were typed. I go back. Redo the spacing. Nothing works. Dunno. Sorry if my stuff is hard to understand. I try to make it easy to read, but without proper spacing it looks like a wreck. Sorry, folks. Don't know if Blogger is at fault or if it's the blogger. Suggestions welcomed.
