If the divs are hidden, they will never trigger the mouseover event.

You will have to listen to the event of some other unhidden element.

You can consider wrapping your hidden divs into container divs that remain visible, and then act on the mouseover event of these containers.

<div style="width: 80px; height: 20px; background-color: red;" 
        onmouseover="document.getElementById('div1').style.display = 'block';">
   <div id="div1" style="display: none;">Text</div>
</div>

You could also listen for the mouseout event if you want the div to disappear when the mouse leaves the container div:

onmouseout="document.getElementById('div1').style.display = 'none';"

There is a really simple way to do this in a CSS only way.

Apply an opacity to 0, therefore making it invisible, but it will still react to JavaScript events and CSS selectors. In the hover selector, make it visible by changing the opacity value.

#mouse_over {
  opacity: 0;
}

#mouse_over:hover {
  opacity: 1;
}
<div style='border: 5px solid black; width: 120px; font-family: sans-serif'>
<div style='height: 20px; width: 120px; background-color: cyan;' id='mouse_over'>Now you see me</div>
</div>

Pass the mouse over the container and go hovering on the divs I use this for jQuery DropDown menus mainly:

Copy the whole document and create a .html file you'll be able to figure out on your own from that!

            <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
            <html xmlns="http://www.w3.org/1999/xhtml">
            <head>
            <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
            <title>The Divs Case</title>
            <style type="text/css">
            * {margin:0px auto;
            padding:0px;}

            .container {width:800px;
            height:600px;
            background:#FFC;
            border:solid #F3F3F3 1px;}

            .div01 {float:right;
            background:#000;
            height:200px;
            width:200px;
            display:none;}

            .div02 {float:right;
            background:#FF0;
            height:150px;
            width:150px;
            display:none;}

            .div03 {float:right;
            background:#FFF;
            height:100px;
            width:100px;
            display:none;}

            div.container:hover div.div01 {display:block;}
            div.container div.div01:hover div.div02  {display:block;}
            div.container div.div01 div.div02:hover div.div03 {display:block;}

            </style>
            </head>
            <body>

            <div class="container">
              <div class="div01">
                <div class="div02">
                    <div class="div03">
                    </div>
                </div>
              </div>

            </div>
            </body>
            </html>

You could wrap the hidden div in another div that will toggle the visibility with onMouseOver and onMouseOut event handlers in JavaScript:

<style type="text/css">
  #div1, #div2, #div3 {  
    visibility: hidden;  
  }
</style>
<script>
  function show(id) {
    document.getElementById(id).style.visibility = "visible";
  }
  function hide(id) {
    document.getElementById(id).style.visibility = "hidden";
  }
</script>

<div onMouseOver="show('div1')" onMouseOut="hide('div1')">
  <div id="div1">Div 1 Content</div>
</div>
<div onMouseOver="show('div2')" onMouseOut="hide('div2')">
  <div id="div2">Div 2 Content</div>
</div>
<div onMouseOver="show('div3')" onMouseOut="hide('div3')">
  <div id="div3">Div 3 Content</div>
</div>

Option 1 Each div is specifically identified, so any other div (without the specific IDs) on the page will not obey the :hover pseudo-class.

<style type="text/css">
  #div1, #div2, #div3{  
    display:none;  
  }  
  #div1:hover, #div2:hover, #div3:hover{  
    display:block;  
  }
</style>

Option 2 All divs on the page, regardless of IDs, have the hover effect.

<style type="text/css">
  div{  
    display:none;  
  }  
  div:hover{  
    display:block;  
  }
</style>
