Link to the challenge:

I don’t know what’s wrong with my code. I tried replacing the ’ with " and it still doesn’t work. I also tried declaring separate margin properties like margin-top instead of using the clockwise method. I also tried clearing the cache and cookies of my browser. Maybe I just made a spelling error or something. I hope somebody could help me.

The following works - the difference with your code is in the use of “unit” with zero margin for “right” and “left”. Try and see if it solves your issue.

[type='checkbox'] {
    margin: 10px 0px 15px 0px;

I inserted ‘px’ but it still doesn’t work

hey you have to define margin by writing margin-top and margin-bottom property then it will accept your answer

It still doesn’t solve the problem. Is this a bug or something?

Don’t define margin left and margin right property only Define margin top and margin bottom property

Still doesn’t work. Maybe I should report this as a bug?

I suggest you to clear your browser history and restart your browser then run this test
