having trouble with this challenge ive done what the example said to do and reviewed video in help option and still I did not achieve goal challenge
Which challenge? What have you tried?
Can you please share your code and describe what isn’t working the way you expect it to?
Assuming that you are on the challenge: “Add Borders Around Your Elements” in Basic CSS:
note the example
thin-red-border' class and create your thick-green-border` class by following said example.
Very important is to remember to apply the class to the image, and details on how to do that is in the hints of the challenge.
Visually a clue that you have done the challenge correctly is that you will see a thick green border around the cat picture in the preview on the right.
For further help, please post what code you have written in that challenge.
