Expansion

Amazing how one can get caught up in appearances. The wide blank left margin of my blog had really begun to annoy me, so I converted it to something called "stretch." And it has. Much indecision over how large the font for the actual posts should be, and no idea as to how to make the right margin justified. I've read through all the "help," but cannot seem to effect this change. Any advice and comments welcome. Note how skillfully I've avoided cleaning up the run-on sentences in the last post.
