It says something is wrong and I can't find out what?

What I wrong here?

Replace this line with your code. 

there are two proper ways to define a border, the border property:

border: 4px solid red;

or the individual property’s:

border-width: 4px;
border-style: solid;
border-color: red;

you seemed to have used some sort of mixture. Your border has two values (it should have 3) so it has to come up with a default color (black) overwriting your border-color on line 18. Either use the border property correctly or the individual border property’s. Hope this helps


Thank you very much!!
