Adding space between sections

[A-1 Electronics]

I would like to add some space between what was originally 'Congrats' and 'Welcome Guest would you like to log yourself in?' I would also like to center these sections. How would I go about doing this?

Difficult to be sure without seeing what changes you have made to your site. But if it's close to default Zen Cart the following addition to your stylesheet would probably do it

h2.greeting {margin-top:20px}

Does it matter where I add this code to the stylesheet?

Probably not, but this would depend upon what other changes you have made. If they don't affect h2 tags or the .greeting class, it shouldn't matter, but would be sensible to put it near the top just after the other headings' styles.

Worked perfectly. I now have a space where I need it. Thanks.
