在做项目时使用到了模态框，一不小心出了错误，大家来看看问题出现在那里吧！
这里面有三个模态框，我就拿一个来举例吧！
开始我是这样写的【出错的代码】：
<!--暂停-->
<li data-toggle="modal" data-target="#myModal1">
<a href="#">暂停</a>
<div class="modal fade" id="myModal1">
<!-- 窗口声明 -->
<div class="modal-dialog modal-lg">
<!-- 内容声明 -->
<div class="modal-content">
<p><img src="../images/BrushProblem/cut.jpg" alt=""></p>
<p>休息一会<span>放松一下</span></p>
<p><button class="btn btn-default" data-dismiss="modal">继续</button></p>
</div>
</div>
</div>
</li>
我把data-toggle="modal" data-target="#myModal1"误写在了模态框的父级上之后就出现了这样的问题。
当点击暂停时他很完美的弹出了我想要的结果：
然而并没有完，当我想要继续时他又弹出了一个黑框，如下：
都是因为data-toggle="modal" data-target="#myModal1"放错了位置才造成了这些错误。
来看看实现这些效果的完美代码吧！
