CSS fade-in background image

Issue

I'm learning CSS and I want to make that on a hover on some text, the text disappears and there is a fade-in on an image. I've tested some things but it doesn't work the way I want to do it.

The text is a link in a and on the hover I set the background image. I could use an in the but I want the text to be in the middle of the and it's already in a with an absolute position.

Here's the HTML :

<div class="header"> 
  <!--<ul>-->
  <div class="header_element">
    <a title="Home" href="page.php"> Home </a>
  </div>

And the CSS :

    div.header_element {
      display: table-cell;
      text-align: center;
      vertical-align: middle;
      height: 100%;
    }

    div.header_element:hover {
      background-position: center;
      background-image: url("hover.png");
      background-repeat: no-repeat; 
    }

Would appreciate if anyone could help me with this.

Solution

You would like to probably use opacity and fade-in effect.

div.header_element {
display: table-cell;
text-align: center;
vertical-align: middle;
}

div.header_element:hover {
background-position: center;
background-image: url("http://dummy-images.com/abstract/dummy-100x100-Rope.jpg");
background-repeat: no-repeat;
    -webkit-animation: fadein 2s; /* Safari, Chrome and Opera > 12.1 */
       -moz-animation: fadein 2s; /* Firefox < 16 */
        -ms-animation: fadein 2s; /* Internet Explorer */
         -o-animation: fadein 2s; /* Opera < 12.1 */
            animation: fadein 2s;
}

@keyframes fadein {
    from { opacity: 0; }
    to   { opacity: 1; }
}

/* Firefox < 16 */
@-moz-keyframes fadein {
    from { opacity: 0; }
    to   { opacity: 1; }
}

/* Safari, Chrome and Opera > 12.1 */
@-webkit-keyframes fadein {
    from { opacity: 0; }
    to   { opacity: 1; }
}

/* Internet Explorer */
@-ms-keyframes fadein {
    from { opacity: 0; }
    to   { opacity: 1; }
}

/* Opera < 12.1 */
@-o-keyframes fadein {
    from { opacity: 0; }
    to   { opacity: 1; }
}

See the jsfidle if it's what you wanted.
