I'd like to use one of the W3C validator logos, but it doesn't match the design of my Web site. Can I change the logo?

No. The W3C Logo provides the organization with its visual identity. As a result, there are strict rules for its use. Changing the W3C logos is not permitted, as it defeats the purpose of the logo, which is to be noticed and identified as W3C
vuoi dire che tutti i "patacchini" (mi piace sto termine ) diversi da quello giallo noto non sono ufficiali?
