I can't get information to look right when published.

Options

Content will look okay when I am working on it, but when I update there are spacing errors throughout.  For ex- I have left spaces between lines of text or have aligned text with a photo, but when I click update, the spacing does not show. When I go to edit it again, it shows several spaces/lines between the text, but this is not showing once published. Does this make sense? I am extremely frustrated :(

 

I am using a template and mostly cutting and pasting content into the text editor using Control C and V as suggested. I think I am doing something wrong with entering spaces or paragraphs....I am not familiar with HTML.

 

I have searched through the help and videos but can't find anything addressing this.
