image zoom effect on hover

Question

The idea is to create a zoom effect on mouseover. But since the height is 'auto' the zoomed in image doesn't contain in the div and increases in height. I have to keep the height 'auto' for responsive design purpose. A way out would be appreciated. Following is the link: http://jsfiddle.net/nitish_8/zaeZ4/

<div class="item">
<img src="images/2.jpg" />
</div>
<div class="item">
<img src="images/2.jpg" />
</div>
<div class="item">
<img src="images/2.jpg" />
</div>
<div class="item">
<img src="images/2.jpg" />
</div>

Answer 1

try out following code for item div hover, hope this will help you

.item:hover img {
    -webkit-transition: all 21s ease-in-out;
    -moz-transition: all 1s ease-in-out;
    -ms-transition: all 1s ease-in-out;
    -o-transition: al 1s ease-in-out;
    transition: all 1s ease-in-out;
    transform:  scale(1.1) ;
    -webkit-transform:scale(1.1) ;
    -moz-transform:  scale(1.1) ;
    -o-transform:  scale(1.1)  ;
    -ms-transform: scale(1.1)  ; 
 }

Answer 2

我认为您可以从item类中删除ovewflow属性，以使div不剪切放大的图像
