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>
