What is the best way to alter the background of a div when hovering over an image?

Question

What is the best way to alter the background of a div when hovering over an image?

I am looking to achieve a unique effect with my thumbnail image and background. Currently, I have the thumbnail image inside a div with another image serving as the background to frame it. My goal is to change the position of the background image from bottom center to top center when hovering over the thumbnail.

Below is the example code:

<div class="image">
   <a class="zoom1" title="Sample title" href="images/xyz-large.jpg"><img src="images/portfolio-xyz.jpg" alt="XYZ Inc" /></a>
</div>

And here is the related CSS:

div.image     { width: 314px; height: 231px; background: url(images/bg_portfolio-img.png) no-repeat bottom center; }
div.image img { position: relative; top: 8px; left: 8px; }

I would like to accomplish this purely using CSS, such as the following snippet:

div image a.zoom1:hover  { background-position: top center;}

Unfortunately, the above CSS code does not work as intended. I may be open to using a jQuery solution, but I would need some guidance on that front as well.

Thank you in advance for your assistance!

Here is a suggestion on how to use the .hover() function:

$(".image img").hover(function() {
  $(this).closest(".image").css({ 'background-position': 'top center' });
}, function() {
  $(this).closest(".image").css({ 'background-position': 'bottom center' });
});

By hovering over an <img> within a class="image", it changes the background position of the div. The same action occurs in reverse when you hover out. If you want to add more styling properties, you can include them in the .css() method. For more information, check out the jQuery documentation.

Using JavaScript provides a simple solution.

If you prefer to use only CSS, consider eliminating the extra div and applying the background image directly to the img element with added padding. This allows for changing the background-position on hover without the need for additional markup.

If the link (a) completely fills its parent div, you can achieve a desired effect with CSS:

div.image:hover { background-position: center top; }

This works when the link completely fills the parent, providing consistent interactivity
However, this method is not compatible with IE6

JQuery Alternative Solution

$(".image a").hover(function(){
  $(this).parent('.image').addClass('hover');
},function(){
  $(this).parent('.image').removeClass('hover');
});

Then style in CSS accordingly:

div.image { background-position: center bottom; }  //default
div.hover { background-position: center top; } //on hover

Additional JQuery Notes

1

To make sure the .hover class is specific enough, consider targeting it within a holding div:

div#some-holding-div div.hover {...}

There should be a suitable holding div in your markup

2

Instead of adding and removing classes, you can directly set CSS properties using jQuery (e.g., changing backgroundPosition dynamically)

These solutions are suggestions and may need to be adjusted to fit your specific requirements - also, they have not been thoroughly tested.
