[Media()] lets you use the media() function to assign responsive values to a declaration, following the [CSS Media Expressions] specification.

``css
/ before /

h1 {
font-size: media(
16px,
(min-width: 600px) 20px,
(min-width: 1000px) 40px,
(min-width: 1400px) 60px
);
}


/ after /

h1 {
font-size: 16px;
}

@media (min-width: 600px) {
h1 {
font-size: 20px;
}
}

@media (min-width: 1000px) {
h1 {
font-size: 40px;
}
}

@media (min-width: 1400px) {
h1 {
font-size: 60px;
}
}
`
