Can you overlay a transparent div on an image

I ran accross this example in the image below that is done in Flash and I was wondering if a similar affect of having a transparent box at the bottom of an image with text on it is possible with CSS or something other then flash?

You can simply create an overlay by CSS only over any image.

.container{
  width:250px; height:250px;
}
.container img{width:100%;height:100%}
.container::before{
  content:'';
  position:absolute;
  left:0;
  top:0;
  background:#fff;
  z-index:9999;
  width:100%;
  height:100%;
  opacity:0;
}
<div class="container">
<img src="https://cdn4.buysellads.net/uu/1/8026/1535654409-Slack-pink_logo.png" alt="" border="0">
</div>

Definitely.

<div style="background-image: url(image.png);" >

  <div style="position:relative; top:20px; left:20px;">
    Some text here
  </div>
</div>

Sure, here is a cross-browser way of doing so:

<html>
  <head>
    <style type="text/css">
      div.imageSub { position: relative; }
      div.imageSub img { z-index: 1; }
      div.imageSub div {
        position: absolute;
        left: 15%;
        right: 15%;
        bottom: 0;
        padding: 4px;
        height: 16px;
        line-height: 16px;
        text-align: center;
        overflow: hidden;
      }
      div.imageSub div.blackbg {
        z-index: 2;
        background-color: #000;
        -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=50)";
        filter: alpha(opacity=50);
        opacity: 0.5;
      }
      div.imageSub div.label {
        z-index: 3;
        color: white;
      }
    </style>
  </head>
    <body>
      <div class="imageSub" style="width: 300px;"> <!-- Put Your Image Width -->
        <img src="image.jpg" alt="Something" />
        <div class="blackbg"></div>
        <div class="label">Label Goes Here</div>
      </div>
    </body>
</html>

This method doesn't require JavaScript, doesn't cause to lose ClearType text in IE, and is compatible with Firefox, Safari, Opera, IE6,7,8... Unfortunately, it only works for one line of text. If you want multiple lines, either adjust div.imageSub div's height and line-height property, or use the following (modifications to the CSS and requires the label to be specified twice).

<html>
  <head>
    <style type="text/css">
      div.imageSub { position: relative; }
      div.imageSub img { z-index: 1; }
      div.imageSub div {
        position: absolute;
        left: 15%;
        right: 15%;
        bottom: 0;
        padding: 4px;
      }
      div.imageSub div.blackbg {
        z-index: 2;
        color: #000;
        background-color: #000;
        -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=50)";
        filter: alpha(opacity=50);
        opacity: 0.5;
      }
      div.imageSub div.label {
        z-index: 3;
        color: white;
      }
    </style>
  </head>
    <body>
      <div class="imageSub" style="width: 300px;"> <!-- Put Your Image Width -->
        <img src="image.jpg" alt="Something" />
        <div class="blackbg">Label Goes Here</div>
        <div class="label">Label Goes Here</div>
      </div>
    </body>
</html>
