Wxsim 3in1 - W3c validation

Hi to all,
today i’ve seen that there are 7 errrors about wxsim3in1 w3c validation (only with rain forecasts)
Here is the link: http://validator.w3.org/check?uri=http%3A%2F%2Fwww.meteocarmignano.it%2Findex.php

Could you help me about this please?
Regards,

Alessandro

I only see 2 errors…

ID’s cant be repeated only classes can, there is a problem as you have already got classes initialized, see if you can merge the CSS id code into the classes code and see if it works.

ID’s are only supposed to be for unique information.
