Here's my code:

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

/* Write the CSS in the media query below */

@media (min-width: 607px) {
  img:nth-child(3n+4) {

Task 1 and 2 should be different CSS rules.

The rule for task 1 that creates the floats should be completely different from the rule created in task 2 that clears them. The task 1 rule should remain as it was at the end of task 1.

It looks like you either modified or replaced the task 1 rule when you made the one for task 2.
