请你帮我解决这个障碍。
我有这个网站here，当我点击圆角图片时，我希望我的红色div更改。
我已经复制了其他网站的代码！
以下是该部分的代码：

有很多方法可以做这样的事情。您可以在各种库中找到许多实现。甚至Bootstrap都内置了这个功能。
话虽这么说，我只是很快就习惯了一些自定义的东西供你观看和玩耍。请参阅Fiddle示例，然后点击红色圆圈，了解他们如何更改以下内容。
HTML：
<ul class="circles">
<li class="circle active" data-toggle="1"></li>
<li class="circle" data-toggle="2"></li>
<li class="circle" data-toggle="3"></li>
<li class="circle" data-toggle="4"></li>
<li class="circle" data-toggle="5"></li>
</ul>
<ul class="boxes">
<li class="box active" data-toggled-by="1">
<h1>Box 1</h1>
</li>
<li class="box" data-toggled-by="2">
<h1>Box 2</h1>
</li>
<li class="box" data-toggled-by="3">
<h1>Box 3</h1>
</li>
<li class="box" data-toggled-by="4">
<h1>Box 4</h1>
</li>
<li class="box" data-toggled-by="5">
<h1>Box 5</h1>
</li>
</ul>
CSS：
ul {
list-style-type: none;
}
li.circle {
display: inline-block;
border: 2px solid red;
width: 50px;
height: 50px;
background: red;
border-radius: 50px;
margin-right: 25px;
-webkit-transition: opacity .15s ease-in-out;
-moz-transition: opacity .15s ease-in-out;
transition: opacity .15s ease-in-out;
cursor: pointer;
}
li.circle:hover {
opacity: .5;
}
li.circle.active {
border-color: black;
}
li.box {
width: 90%;
display: none;
background: white;
height: 300px;
display: none;
}
li.box.active {
display: block;
}
JavaScript（jQuery）：
$('.circle').click(function() {
// De-activate previously active circle
$('.circle.active').removeClass('active');
// Activate clicked circle
$(this).addClass('active');
// Get toggle ID of clicked circle
var toggleId = $(this).data('toggle');
// De-activate previously active box
$('.box.active').removeClass('active');
// Activate box with corresponding toggle ID
$('.box[data-toggled-by="' + toggleId + '"]').addClass('active');
});
