Confused on this challenge task. Question 2 of 3

Here is the code I used to get the correct answer for the question on Challenge Task 2 of 3

"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."

@media (min-width: 607px) {
  img {
    float: left;
  }
  img:nth-child(3n+4) {
    clear: left;
  }
}

4n + 3 isn't every 7th child. It means start with the 3rd child then select every 4th child after that.

"...targets the fourth img child element first, then every third img that follows"

This would be 3n+4.

Also, for this {clear: float-left;} , it should be {clear: left;}

@media (min-width: 607px) { img{ float: left;

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

If only treehouse offered hints -_-

very helpful. But if your not 100% sure of this logic whats the best way to let this stuff sink in? [Practice] Im guessing?

There's two errors in your error.

1. 4n already refers to the 4th child - I don't even know if 4n + 3 works but if it does it's referring to every 7th child
2. clear is a property all in itself, like float, you don't have to re-state float, you just indicate the 'direction' where you want to clear (left, right, both are the standard options)

thanks

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

This is the correct answer:

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

The video before the quiz goes into this

You need to use nth-child(4n).
