First challenge in the Add Style and Icons section, and it's not picking up my coding...

Here is my code for the first challenge...i check and it keeps saying 'make margin 0... then it gripes about font size... then padding... almost seems random?

From main.css /********************************* Page: Contact **********************************/

.contact-info { list-style: none; padding: 0; margin 0; font-size: 0.9em; }

From Contact.html:

<ul class="contact-info"> <li class:"phone"><a href="tel:111-1111">111-1111</a></li> <li class:"mail"><a href="mailto:JDW@example.com">example@example.com</a></li> <li class:"twitter"><a href="http://twitter.com/intent/tweet?screen_name=testtweet">@testtweet</a></li> </ul>
