Freecodecamp: Issue about Challenge - Target the same element with multiple jQuery Selectors

Challenge Name

Only add one class with each of your three selectors.

Issue Description

Only the task "Only add one class with each of your three selectors." fails. I think I've done that only one class is added with the the different selectors in my code.
