Hey Ricard,

There are two small errors:

  1. Typo --> Missing the 'd' on `first-child'

  2. Spacing issue --> When you are using pseudo elements, there cannot be a space between the element and the pseudo-selector. With a space, CSS treats them as separate. No space and CSS knows they are attached. li:first-child (no spaces anywhere.

Fix those up and you're good to go. :)
