Thank you very much Sunfighter
In fact, mneanwhile, I found that all you have to do is to reduce the size of the entries (in this case, coutries of the world, where United States of America were the main culprit...) I solved it by reducing the length of the entries i.e. United States (USA). I am going to play with your code to see if it is better.
meanwhile, maybe you can help me with another CSS problem: I have apage with one sidebar and a main area. I would like to get another sidebar on the other side, but everything I tried does not work, e.g. margin-left: auto ;
margin-right: auto ;
but all this does is to push to exiasting sidebar down, as if assuming that the space to the left and right belongs to it as a margin.
Can you help, please?
