I strongly suspect that none of you care about this, but it has been driving me CRAZY!
I switched months ago to the new and so-called improved blogger with a new look for this blog. However, I quickly noticed that the line spacing was messed up. All text lines after a block quote became single-spaced! It looked like crap and I couldn't figure out how to fix it. I emailed blogger and they were no help, yada, yada, yada.
Well, I finally found this blog and was able to adjust the CSS style sheet code to fix the problem.
Now, I'm very happy.
