Why do we have to use multiple classes and elements when styling contact info?

So I'm slightly confused why we have to use: .contact-info li.phone a when styling contact info? Why couldn't I just use the .phone class or li.phone a, why is the .contact-info class necessary? Is it just to better specify what we're trying to style?

Thanks!

It's not necessary to be this specific.

In fact, if the phone class is not used elsewhere, this can just be ".phone a". It cannot be simply ".phone" because that would target the li element instead of the a element.

My guess is using it in the video is just an example of how to construct selectors with high specificity, or a precaution for possible future use of the phone class elsewhere.

Oh okay, that's what I was thinking but didn't hear it being mentioned anywhere so I wanted to make sure. Appreciate your help.
