Multiple modals not working properly
<p>I apologize if this is been answered before but I've been staring at this code for hours and cant figure out why it is behaving the way it is.  </p>

<p>I have a page with 3 modal windows on it that I am using javascript to trigger. Now with just one modal window it works fine, however I have tried adding two more windows and the first link for the first window triggers the third modal and then the close function does not work anymore. </p>

<p>Here is my code:</p>

<p>CSS:</p>

<pre><code>&lt;style&gt;
/* The Modal (background) */
.modal {
display: none; /* Hidden by default */
position: fixed; /* Stay in place */
z-index: 1; /* Sit on top */
left: 0;
top: 0;
width: 100%; /* Full width */
height: 100%; /* Full height */
overflow: auto; /* Enable scroll if needed */
background-color: rgb(0,0,0); /* Fallback color */
background-color: rgba(0,0,0,0.4); /* Black w/ opacity */
}

.modal1 {
display: none; /* Hidden by default */
position: fixed; /* Stay in place */
z-index: 1; /* Sit on top */
left: 0;
top: 0;
width: 100%; /* Full width */
height: 100%; /* Full height */
overflow: auto; /* Enable scroll if needed */
background-color: rgb(0,0,0); /* Fallback color */
background-color: rgba(0,0,0,0.4); /* Black w/ opacity */
}

.modal2 {
display: none; /* Hidden by default */
position: fixed; /* Stay in place */
z-index: 1; /* Sit on top */
left: 0;
top: 0;
width: 100%; /* Full width */
height: 100%; /* Full height */
overflow: auto; /* Enable scroll if needed */
background-color: rgb(0,0,0); /* Fallback color */
background-color: rgba(0,0,0,0.4); /* Black w/ opacity */
}

/* Modal Content/Box */
.modal-content {
background-color: #fefefe;
margin: 15% auto; /* 15% from the top and centered */
padding: 20px;
border: 1px solid #888;
width: 80%; /* Could be more or less, depending on screen size */
}

/* The Close Button */
.close {
color: #aaa;
float: right;
font-size: 28px;
font-weight: bold;
}

.close:hover,
.close:focus {
color: black;
text-decoration: none;
cursor: pointer;
}

/* Modal Header */
.modal-header {
padding: 2px 16px;
background-color: #5cb85c;
color: white;
}

/* Modal Body */
.modal-body {padding: 2px 16px;}

/* Modal Footer */
.modal-footer {
padding: 2px 16px;
background-color: #5cb85c;
color: white;
}

/* Modal Content */
.modal-content {
position: relative;
background-color: #fefefe;
margin: auto;
padding: 0;
border: 1px solid #888;
width: 80%;
box-shadow: 0 4px 8px 0 rgba(0,0,0,0.2),0 6px 20px 0 rgba(0,0,0,0.19);
-webkit-animation-name: animatetop;
-webkit-animation-duration: 0.4s;
animation-name: animatetop;
animation-duration: 0.4s
}

/* Add Animation */
@-webkit-keyframes animatetop {
from {top: -300px; opacity: 0} 
to {top: 0; opacity: 1}
}

@keyframes animatetop {
from {top: -300px; opacity: 0}
to {top: 0; opacity: 1}
}
&lt;/style&gt;
