Just a slight error in your media query selector. Screen should come before and, so it should look like this:

@media screen and (min-width: 480px) {
  h1 {
    font-size: 2.5em
  }
}

Try moving your media query to the top. Of your cars file. You want your media queries to go from smallest width to largest.

If I were you, I'd download the project files so you have a working example, and play with some code you've written so you can see what's happening in the dev tools of whichever browser you're using. With the Chrome dev tools, you can change the css in the browser to see what changes.

Everything between the @media and the opening parenthesis, you should consider as a boolean expression, like something that will either evaluate to true or false, so Ryan is right. As far as Malachi's response, it doesn't matter if the media query is at the top or bottom of this code challenge. You can put it in both places for the working solution. As Nick showed in the video, it's common to add after the rest of your styles.

Second, the media type (screen in this case) is optional in this case, so you don't even really need it. Look at the mdn docs for more about media queries: https://developer.mozilla.org/en-US/docs/Web/CSS/Media_Queries/Using_media_queries
