Line Spacing - how to adjust

If you are having trouble getting headlines and sub-heads  (Heading 2 or Heading 3 formats) to be single-spaced, adjust the line spacing in a Word document and then insert into the web page -- be sure to use the "Paste as Plain Text" tool.

For some reason, the CMS puts a lot of space between lines that are Heading 2 and Heading 3, and won't let you adjust in the text editor box.
