When a mouse hovering over the image, the image will be blurred and there will be text showing up on top of the image. I tried it myself using the code below but it appeared that the "text" move outside the image when hovering ...can anyone tell me why?

Code:

Html:

<span class ="row_1">
<a href="#">
<div class = "caption"> testing </div>
<img class = "img_link" src="image/food/food1.jpg" />
</a>
</span>

CSS:

.caption
{
display: none;
}

Jquery:

    $('a').hover(
    function(){
    var image = $(this).find('img'),
     caption = $(this).find('div');
     caption.width(image.width());
     caption.height(image.height());
     caption.fadeIn();
    },
    function(){
     var image= $(this).find('img'),
        caption = $(this).find('div');

    caption.width(image.width());
    caption.height(image.height());
    caption.fadeOut();
});

First off, I had to correct your HTML. A div (block-level element) is not a valid child of either a span or a elements (both of which are in-line elements). So, amended your HTML to the following:

<span class="row_1">
    <a href="#">
        <span class="caption">testing</span>
        <img class="img_link" src="http://davidrhysthomas.co.uk/img/dexter.png" />
    </a>
</span>​

That said, I'd suggest, if possible, using plain CSS for this:

a {
    display: inline-block;
    position: relative;
}
.caption {
    display: none;
    position: absolute;
    top: 0;
    left: 0;
    right: 0;
    background-color: #333; /* for browsers that don't understand rgba() notation */
    background-color: rgba(0,0,0,0.6);
    color: #f90;
    font-weight: bold;
    line-height: 1.1em;
}
a:hover .caption {
    display: block;
}​

You can, with CSS3 transitions, even implement the fade-in transition as well (which gracefully degrades for those browsers that don't understand/implement transitions, albeit in this example you might have to use a Microsoft proprietary filter for older-IE pliance):

a {
    display: inline-block;
    position: relative;
}
.caption {
    opacity: 0;
    position: absolute;
    top: 0;
    left: 0;
    right: 0;
    background-color: #333; /* for browsers that don't understand rgba() notation */
    background-color: rgba(0,0,0,0.6);
    color: #f90;
    font-weight: bold;
    line-height: 1.1em;
    -webkit-transition: all 1s linear;
    -o-transition: all 1s linear;
    -ms-transition: all 1s linear;
    -moz-transition: all 1s linear;
    transition: all 1s linear;
}
a:hover .caption {
    opacity: 1;
    -webkit-transition: all 1s linear;
    -o-transition: all 1s linear;
    -ms-transition: all 1s linear;
    -moz-transition: all 1s linear;
    transition: all 1s linear;
}​

If you must use jQuery then I'd suggest keeping it very, very simple:

​$('.row_1 a').hover(
    function(){
        $(this).find('.caption').fadeIn(1000);
    },
    function(){
        $(this).find('.caption').fadeOut(1000);
    });​​​​​​​​

References:

• CSS transition.
• fadeIn().
• fadeOut().
• find().

You dont need Javascript for this. This snippet below is enough to bring up the caption.

a:hover .caption { display: block; }

But the caption has to be positioned correctly first.
