On the ul with class="contact-info" why did he use a class instead of an id? is it preference or is that the best practice?

231,198 PointsClasses are re-usable, ID's have higher specificity.
As Isaiah mentioned, classes can be used on multiple elements, and an element may have more than one class. But ID's must be unique (per page).
Also, ID's have a higher CSS specificity, which means rules based on them will override rules based on class, no matter where they occur in the cascade. Sometimes this can be desirable, but when it is not it would be another reason to chose classes.

1,378 Pointsclasses are used when you want to manipulate multiple elements at a time and id's are used when you want to manipulate a single element.
you can have multiple classes but you can only have 1 id
