<html><head><style>#div { width: 100px; margin: 5px 0; padding: 5px; color: white; background-color: #ED8029; text-align: right; border-radius: 5px;}#div:active{ height:500px;}.ease { -webkit-transition: height 0.5s ease; -moz-transition: height 0.5s ease; -o-transition: height 0.5s ease; -ms-transition: height 0.5s ease; transition: height 0.5s ease;}</style></head><body> <div id="div" class="ease">ease</div></body></html>
