In the "Create a Media Query" challenge, the instructions and the test don't match. The instructions say:

Add a media query, so that the p tag has a font-size of 10px when the device's height is smaller than 800px.

Smaller than 800px means 799 or less, so the correct media query should be "max-width: 799px". The test actually passes with "max-width: 800px", which translates into English as 800px or smaller.

Basically, the instructions call for width < 800, but the test checks for width <= 800. Either one is fine, but they need to match each other.
