So when you first run the test and it fails it may mention something about setting the display to block. You do that and the test fails again but this time the error message will be different. It may tell you to set the height or margin…don’t recall off the top of my head.
Click on the red button to see which test is failing and read the text to see what you need to do to correct it. Fixing one may lead to another but you’ll get there.
