Q:

I am applying modal from Bootstrap but it is not closing properly

I am applying modal from Bootstrap but it is not closing properly. When I click on close button on top-right, it crashes and when I click anywhere else on modal it closes normally. I tried many times but this problem is constant.   

html,
body {
  height: 100%;  

}
body {
  padding-top: 20px;    
  background: #f9e0b5 ;
  background-size:100%;
  background-repeat: repeat-y; 
}  
.pro{
  background:linear-gradient(white, #e7d5b5);  
  margin:10px 40px 0px;
  height:250px;
  border-radius:30px;
  box-shadow:5px 5px 5px black;
  cursor:pointer;
}
#pro4{
  position:relative;
  left:370px;
}
.pro-caption{
  font-size:17px;
  font-weight:bold;
  font-family:"Comic Sans MS", cursive, sans-serif;
  color:#6b412b;
  background:linear-gradient(white, #f5e5d7); 
}

A:

As you can see, you have set the data-target property to modal1 div, so you need to have seperate div i.e <div id="modal1"></div>  where you can place your content which you have commented.
<div class="col-md-3 pro" data-toggle="modal" data-target="#modal1"></div>

Basically you have placed your content in the class that toggles the popup which you need to take that out and place it in <div id="modal1"></div>, the rest is fine.
Please try below code. I hope this helps you.
