Multiple image modals with multiple captions

i need to have multiple image modals with different bodies. Each image would have a separate description that shows up when its clicked. I've only found other answers that display each images alt but I need it to display other text when its clicked. I have it right now where i have multiple image modals but each one opens the same caption.

The javascript

function onClick(element) {

  document.getElementById("modal01").style.display = "block";

}

The html

<div class="container1">
    <img src="https://images-na.ssl-images-amazon.com/images/M/MV5BMTczNTI2ODUwOF5BMl5BanBnXkFtZTcwMTU0NTIzMw@@._V1_SY1000_CR0,0,674,1000_AL_.jpg" style="max-width:100%;cursor:pointer"
    onclick="onClick(this)" class="modal-hover-opacity">
  </div>
  <div class="container1">
    <img src="https://images-na.ssl-images-amazon.com/images/M/MV5BMTUyNzk3MjA1OF5BMl5BanBnXkFtZTcwMTE1Njg2MQ@@._V1_SY1000_CR0,0,674,1000_AL_.jpg" style="max-width:100%;cursor:pointer" 
    onclick="onClick(this)" class="modal-hover-opacity">

  </div>
  <div class="container1">
    <img src="https://images-na.ssl-images-amazon.com/images/M/MV5BMTM0MDgwNjMyMl5BMl5BanBnXkFtZTcwNTg3NzAzMw@@._V1_.jpg" style="max-width:100%;cursor:pointer" 
    onclick="onClick(this)" class="modal-hover-opacity">

  </div>



<div id="modal01" class="modal" onclick="this.style.display='none'">
  <span class="close">&times;&nbsp;&nbsp;&nbsp;&nbsp;</span>
  <div class="modal-content">
    <img id="img01" style="max-width:100%">
    <div id="caption" style="color:white">This is the caption</div>
    <div id="2ndcaption" style="color:white">this is the 2nd</div>
    <div id="3rdcaption" style="color:white">This is the 3rd</div>
  </div>
</div>

and the CSS

.modal {
z-index:1;
display:none;
padding-top:10px;
position:fixed;
left:0;
top:0;
width:100%;
height:100%;
overflow:auto;

}

.modal-content{

    position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
}


.modal-hover-opacity {
opacity:1;
filter:alpha(opacity=100);
-webkit-backface-visibility:hidden
}

.modal-hover-opacity:hover {
opacity:0.60;
filter:alpha(opacity=60);
-webkit-backface-visibility:hidden
}


.close {
text-decoration:none;float:right;font-size:24px;font-weight:bold;color:white
}
.container1 {
width:200px;
display:inline-block;
}
.modal-content, #caption {
