header .profile-image selector

Hi,

Why do we need to include the "header" part in the "header .profile-image" selector in the CSS when changing the hover state? Could we just use ".profile-image"?

Cheers.

Hi jasont2,

Yes. Technically, in this situation you could just use the class selector .profile-image by itself, but classes do not have to be unique on a page. So you could presumably reuse the "profile-image" class throughout a page (or series of pages), and so adding the specificity of header .profile-image assures you that only the profile-image in the header changes on hover.
