Create a breakpoint for devices 480 pixels wide or larger. Inside the breakpoint, set the h1 font-size to 2.5em.

:warning: It doesn't look like you've written any code yet.

You need to create a media query at the bottom of the CSS file.

As Steven Parker said, you need to be sure to call the media query within your code. Some people argue that all of your media queries need to be at the bottom of your file, while others argue that it should be next the element you're changing with that query. The first method keeps all your responsiveness in one spot. The other keeps it next to the chunk that you're working on (more common in SASS/SCSS), making it so that you don't have to keep scrolling up and down in your code.

Whichever way you choose, just be sure the media query comes last in your set of declarations.

All that being said, I believe the code you're looking for can be seen below. You can see I'm calling the media query on the screen when the screen has a min(imum)-width of 480px. It is within those selectors that you can then place your h1 font-size change. Hope that helps. 

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