I picked up this code on responsive email patterns and I cant get it to actually expand with the content when sent to a mobile device. Am I doing something wrong with it (like not changing the actual URL) or is it just really not supported?

/* Full to Accordion Pattern CSS */
    @media only screen and (max-width: 450px) {
        table[class="pattern"] .story p {
            max-height: 0;
            overflow: hidden;
            margin: 0;
        }
        table[class="pattern"] .story h1 a { display: block; position: relative; }
        table[class="pattern"] .story h1 a:after {
            content: '+';
            position: absolute;
            top: 0;
            right: 0;
            display: block;
        }
        table[class="pattern"] #story1:target p,
        table[class="pattern"] #story2:target p,
        table[class="pattern"] #story3:target p {
            max-height: 999px;
            margin: 16px 0;
            -webkit-transition: max-height 0.5s ease-out;
            -moz-transition: max-height 0.5s ease-out;
            -ms-transition: max-height 0.5s ease-out;
            -o-transition: max-height 0.5s ease-out;
            transition: max-height 0.5s ease-out;
        }
    }
</style>
