It's hard for us to know what's causing the issue you are having if you don't show us your code. For some tips on how to do that, check out the tips for asking questions video located in the right hand sidebar.

Hey Marie,

That code challenge has 3 parts all dealing with relative length units. If you're having trouble, I suggest going back and re-watching some of the tutorial videos that deal with this topic. In case you're still stuck after that, let me give you a few hints that I think will help you solve the challenge.

Relative Units: 1em = 16px by default (the browsers default of 16px is given in code challenge instructions).

So, for example, if you needed to define a value of 64px using em units it would be 4em.

1rem = the font size of the root element of the page.

So, for example, if you know the font size of the root element of the page is 16px, a value of 2rem would represent a value of 32px.

Hope this information helps you pass the challenge! Good luck.

My apologies gentlemen, I reposted this question with the code a few minutes after this post and Dave was kind enough to show me what I was doing wrong. Thanks for checking in though.
