Media queries will definitely work inline through MailChimp. Basically you just assign a class to the element you want to hide, like "desktop-only," and then apply a CSS rule to that selector to display:none
when the browser width is below a certain pixel width.
@media only screen and (max-device-width: 480px) {
.desktop-only {
display:none;
}
}
