     <img src='b.jpg' />
     <img src='c.jpg' />
     <img src='d.jpg' />

</div>

Thanks for the help....

Answer 1

Just remove all the transform properties from the original declaration. Since the images are, by default, scaled to 1 , you don't need to declare that. Anything that you set in an element's :hover pseudo class is reverted to its default when the mouse is removed.

Here is an example.

Here's the final CSS:

.imgDiv:hover img{
    -webkit-transform:scale(1.15, 1.15);
    -moz-transform:scale(1.15, 1.15);
    -o-transform:scale(1.15, 1.15);
    -ms-transform:scale(1.15, 1.15);
    transform:scale(1.15, 1.15);
}

Of course, if you were trying to apply this to each image, then you'd still remove the .imgDiv img declaration and change .imgDiv:hover img to .imgDiv img:hover .

Here is an example of that in action.

Just put the :hover on your images

.imgDiv img:hover{
    -webkit-transform:scale(1.15, 1.15);
       -moz-transform:scale(1.15, 1.15);
        -ms-transform:scale(1.15, 1.15);
         -o-transform:scale(1.15, 1.15);
            transform:scale(1.15, 1.15);
}

Adding a transition you got a nice transition effect on hover:

.imgDiv img:hover{
    -webkit-transform:scale(1.15, 1.15);
    -moz-transform:scale(1.15, 1.15);
    -o-transform:scale(1.15, 1.15);
    -ms-transform:scale(1.15, 1.15);
    transform:scale(1.15, 1.15);
}

.imgDiv img {    
    -webkit-transition: all .2s ease-in-out;
    -moz-transition: all .2s ease-in-out;
    -o-transition: all .2s ease-in-out;
    -ms-transition: all .2s ease-in-out;
    transition: all .2s ease-in-out;
}
