解决方法
您可以通过转换高度，填充和边框宽度来实现此目的。这是一个例子：
$('.run-css').click(function() {
$('.cont').toggleClass('toggled');
});
.cont {
width: 100px;
height: 100px;
border: 1px #CCC solid;
background-color: #EEE;
padding: 5px;
-webkit-transition: height .3s linear,padding-top .3s linear,padding-bottom .3s linear,border-top-width .3s linear,border-top-width .3s linear;
transition: height .3s linear,border-top-width .3s linear;
}
.toggled {
overflow: hidden;
padding-top: 0;
padding-bottom: 0;
height: 0;
border-width: 0 1px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.2.3/jquery.min.js"></script> <button class="run-css">CSS slideToggle</button> <div class="cont">Toggle this div</div>
