Simplest jQuery Spotlight Effect

This is a Simplest jQuery Spotlight Effect

 

1. HTML

We will use divs instead of ul list here. I have tested it with UL before, and it will work perfectly fine, you just have to style is with CSS. The caption for the thumbnail will be obtained by jQuery from the anchor Title.

2. CSS

CSS is pretty simple, if you’re using different image size, you might need to adjust the position of caption. Also, we are using a little bit of CSS3 here, we’re using drop shadow, so when you mouse over the item, you will able to see them in firefox, chrome and safari, maybe opera but definitely not internet explorer.

body {
font-family:arial;
margin-top:70px;
}

img {border:none;}

#items a {
text-decoration:none;
color:#3deeee;
}

#items {
width:786px;
margin:0 auto;
}

#items .item {
display:block;
width:190px;
height:120px;
border:2px solid #666;
float:left;
position:relative;
}

#items .item .caption {
position:absolute;
top:80px;
left:2px;
padding:3px;
font-size:10px;
width:180px;
display:none;
background:#000;
}

.clear {
clear:both;
}

.effect {
/* CSS3 shadow */
box-shadow: 0 0 10px #444;
-moz-box-shadow: 0 0 10px #444;
-webkit-box-shadow: 0 0 10px #444;
}

3. Javascript

ALright, here we come to the script that makes everything alive. The way it works is really simple, when we mouse over the item inside the #items, it will set the opacity of the siblings of the item to 0.1, add drop shadow effect and then display the caption. If the user left the #items block, everything is reset back to default

$(document).ready(function () {

//loop through all the children in #items
//save title value to a span and then remove the value of the title to avoid tooltips
$('#items .item').each(function () {
title = $(this).attr('title');
$(this).append('' + title + '');
$(this).attr('title','');
});

$('#items .item').hover(
function () {
//set the opacity of all siblings
$(this).siblings().css({'opacity': '0.1'});

//set the opacity of current item to full, and add the effect class
$(this).css({'opacity': '1.0'}).addClass('effect');

//show the caption
$(this).children('.caption').show();
},
function () {
//hide the caption
$(this).children('.caption').hide(); 
}
);

$('#items').mouseleave(function () {
//reset all the opacity to full and remove effect class
$(this).children().fadeTo('100', '1.0').removeClass('effect'); 
});

});
