I'm wondering why it wouldn't work to use .primary-col,.secondary-col as selectors to make the columns.I've tried it and nothing works on the paragraphs.

But you should be able to get the same results using ".primary, .secondary" as the selector.

Thank you for this! I was confuse for a while till you mentioned that we could also produce the same result with '.primary, .secondary'. This was a tricky challenge, helped me remembered that we can actually give 2 names of class to the tags.
So kind of you to help out, I literally see you in almost all the questions posted by other students. haha
Luke.

.primary { width: 50%; display: inline-block; float: left; padding-right: 10px; }
.secondary { width: 50%; display: inline-block; float: right; padding-left: 10px; }
Worked for me. Would there be an unintended consequence I didn't see ?

6,125 PointsThank you. I didn't realize the space was an issue.
