task one question:Inside the media query, create a new rule that targets img elements. Then, float the images left.

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

task one said its the correct answer but on attempting question two it gave me an error "oops task one could not pass.

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;
  }
}

Hi Nyasha,

You appear to have changed the same selector for task two, for each task the challenge is expecting a new selector so you should have the following from task one and then your code for task two follows it.

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

  /* Task two here */
}

Happy coding!

could also do this : 

@media (min-width: 607px) {
  img[src*="thumb"] {
  float: left;

  }
}
