greetings, any and all. i am a new user and would be very grateful indeed for any help that anyone might offer.

i'm starting a new business website:

my question is specific, at the moment, although any other comments would also be appreciated. As for the site itself, i 'put it together' myself using kompozer, however i've been told that the web pages do not appear correctly in other browsers/OS's.

can anyone verify that there is an issue that i must resolve and perhaps let me know whether this is a CSS problem? i know nothing about this at all and it doesn't seem easy to 'pick it up' quickly without any prior skills (which admittedly i lack!).

thanks in advance. sz
