I ran a page of my site through the w3 Validator, and it mentioned this error:
"Line 30, Column 10: ID "portfolioitem" already defined"
I read online that other people with this problem ended up making "classes" instead. Right now I'm using a div called #portfolioitem to float 3 elements in a container. What exactly should I be doing instead? What do I make classes of instead of using #portfolioitem multiple times in my page?
Thank you in advance.
