The @media CSS at-rule can be used to apply part of a style sheet based on the result of one or more media queries. With it, you specify a media query and a block of CSS to apply to the document if and only if the media query matches the device on which the content is being used.
/* At the top level of your code */
@media screen and (min-width: 900px) {
article {
padding: 1rem 3rem;
}
}
/* Nested within another conditional at-rule */
@supports (display: flex) {
@media screen and (min-width: 900px) {
article {
display: flex;
}
}
}@media (max-width: 350px) {
:root {
--penguin-size: 200px;
