Learn CSS Foundations Projects - CSS Foundations Exercise B

Tell us what’s happening:

I´ve completed all the tasks of the exercise, but for some reason still appearing this check without being completed: Failed:The fourth element should have a font-size of 24px.
If you check my code you´ll see that I put this part on my css code.

So, I hope someone has the answer.

Your code so far

Maybe you are not respecting this part of the user stories?

The font-size of the fourth element should be set with a class attribute. The font-weight and the color should be set with an id attribute.

Totally right Ilenia, I´ve forgot that I could link a ID and a class on the same div. Thanks for your quick response :slight_smile: .
