The proper attribute to group a class of elements together is...
class. It is not a CSS/JS property. It is a logical grouping, just as
ID is a *unique* identifier.

The blink tag works in some browsers too. Doesn't mean you should use
it. And I certainly see no reason to duplicate IDs when you can simply
use class.
