    <script type="text/javascript">
 $(function () {
            var boxWidth = $(".box").width();
 $(".slide-left").click(function(){
                $(".box").animate({
                    width: 0

                    width: boxWidth
                });
 });
 });
 </script>
</head>

<button type="button" class="slide-left">关闭</button>
<button type="button" class="slide-right">展开</button>

When we click the close button, the width of the div containing the text will be slowly changed to 0 through the animate() method until the click is reached Shrink animation effect.

When we click the expand button, the animate() method will also be used, but this time the div with a width of 0 is restored to its original size to achieve the animation effect of clicking to expand.

The effect is shown in the figure below:

animate() method Performs a custom animation of a CSS property set.

This method changes an element from one state to another through CSS styles. CSS property values change gradually, allowing you to create animated effects.

Only numeric values can be animated (such as "margin:30px"). String values cannot be animated (such as "background-color:red").
