I'm having trouble identifying the issue with this code. The background color remains white and doesn't change as expected.
<style type="text/css">
h1 {
position: absolute;
text-align: center;
width: 100%;
font-size: 6em;
font-family: Roboto;
transition: all 0.5s;
}
@media screen and (min-width: 0px) and (max-width: 400px) {
background-color: red;
}
@media screen and (min-width: 401px) and (max-width: 599px) {
background-color: green;
}
@media screen and (min-width: 600px) {
background-color: blue;
}
</style>
