nth-child code challenge?

I have checked my solution for this code challenge in the community multiple times. I don't see what I am doing wrong unless there is simply an error in the page. Others have reportedly passed with the exact same response.

https://teamtreehouse.com/library/css-selectors/advanced-selectors/nth-pseudoclass-challenge

Challenge: "We want three floated images per row. In the media query, create a pseudo-class selector that targets the fourth img child element first, then every third img that follows. Then, add a clear property that clears the left float."

/* Write the CSS in the media query below */
@media (min-width: 607px) {
  img {
    float: left;
  }
  img :nth-child(3n+4) {
    clear: left;
  }
}

Hi there! Not quite, but you are correct that this is a recurring theme. CSS can be very picky about whitespace and this is one of those times when a space is make or break. In this case, it breaks your code. To be clear, this is not specific to Treehouse or the challenge checker but very really will make it so that your CSS in the world at large will break.

You have a space between img and nth-child. Take a look:

/* You wrote */

  img :nth-child(3n+4) {
    clear: left;
  }

/* That should be */
  img:nth-child(3n+4) {  /* note the removal of the space */
    clear: left;
  }

Hope this helps! :sparkles:
