Looking at the parameters for both these selectors, I can't see the benefit of using ID when Class can be used to apply the same changes to every instance in the document. Is there a marked reason to use ID instead?

Courses Plus Student 8,772 PointsHi there, an id can be used to identify one element, whereas class can be used to identify more than one. id is unique. So, id is a better choice when unique element to be targeted.
