Hey,

IDs should be unique, to one element, and there should only be one ID per element, which should also be unique to that element.

If you want to create a method to add "red border" to multiple elements, I'd suggest using a class instead, as an element can have multiple classes added to it, and they don't have to be unique to that element only either. :)

  .red-border {
     border: solid 4px red;
  }

And then simply add this class to the elements you wish to have a red border.

Hope this helps.
