Question

Please i need your help with how to alternate background colours for my comments system. So that red and blue will be alternating for every other element. So far this is what i’m trying to make work, but to no success.

Thanks for your time and patience.

  #comment :nth-child(odd) {
     background-color: red;
   }

   #comment :nth-child(even) {
      background-color: blue;
   }


     #comment {
    color: green;
    margin: 5px auto;
    padding: 5px auto
     width: 100px;
    }

Answer 1

There is a typo. It’s called background-color, not bacground-color in the second selector.
