Bug In Code Challenge

There is a bug in this code challenge, the correct answer is not being accepted.

Here's a screenshot of the page: https://plus.google.com/100996303071825809110/posts/ePkBHgVCTpX

In Task No. 2 the correct answer is not being accepted and the same code is being told to insert.

It was said that if we find a bug then contact support directly, but then the support told me to post it here, so here it is.

Have A Nice Day! Wish You Greater And Greater Health! Thank You! Regards, Samarth

Hi Samarth,

You were so close, your argument should have 4n inside of it. Like this:

@media screen and (min-width: 480px) {
  #gallery li {
    width: 28.3333%
  }

  #gallery li:nth-child(4n){   /* Note the 'n' in the argument */
    clear: left;
  }
}

Keep up the good work though!

Greetings! Mr. Ferdinand!

I have tried it without the "n" in the Treehouse Workspaces and also in real life projects, and it works absolutely correctly. I have never used the "n" in the pseudo selector. And also, the code challenge shows a different error if the correct element is not being selected.

Why isn't it accepting it then?

Thank You! Best Regards, Samarth

Putting the 'n' in, is just good practise. Unfortunately for the challenge, that is just the way the test was written, you'll find a few of these, where an answered could be considered true, but is not accepted. I tend to look at the documentation, which will usually show different ways of accomplishing the same thing, and then try those 'methods' in the challenges.

Treat the challenges like an open book test, that's how I see it anyways.

Have a nice day!

Do you prefer the W3C documentation? Or just any good one?

Yes, I always try to get my answers/solutions from official documentation. That way, I know I am always implementing the latests changes. Though I do also use the site Michael has posted( css-tricks.com ) for css.

Greetings! Gentlemen!

Thanks For The Help Gentlemen! So I Have seen that both of them work in real life projects, with the "n" and without the "n" so guess the code challenge should accept it too. It's okay for it to be a good practice to insert the "n" in there, but when it works without it the code challenge should accept it too.

Thanks For Your Help Gentlemen! Have A Brilliant Day! Wish You Greater And Greater Health!

Thank You! Warm Regards, Samarth

Hi There! I'm actually not marking any of these two answers as best because both of you guys answered it and the're both the same, just answered at different times, what should I do?

Hi Samarth,

You forgot to add an "n" after the 4. Check out the code below:

 #gallery li:nth-child(4n) {
    clear: left;
  }
