Correct.

It's depends what you need it for.

An ID is used to identify a *single* element in the document and can
also be used as anchor (with "#id" at the end of the URL - when opening
such an URL the browser automatically scrolls the view so the element is
inside the current viewport) while classes are a visual property. A
single element can have multiple classes but only one ID which has to be
unique for the document.
