I have a link and when user hover mouse over it, it should display a box (div) under the link. The box should overlay whatever is under it. How can I do it using css or javascript?
You have an absolutely positioned div that is hidden, and a child of the link. Then, when you hover over the link, you should unhide the div. I can't provide full CSS, and I haven't tested this, but that should get you started. You'll have to play around with the positioning and sizes.
Somewhere<div class="desc">This is hidden.</div>
a.special { position:relative; }
a.special div.desc { background-color:white; display:none; position:absolute; z-index:100; }
a.special:hover div.desc { display:block; }
This would be the pure-CSS way.
I have created a sample here. You can modify from there to suit your needs.
<div class="hover">Hover here</div>
<div class="overlay" style="visibility:hidden">
<img src="http://www.google.com/images/logos/ps_logo2.png" alt="google" />
</div>
$(document).ready(function()
{
$("div.hover").mouseover(function ()
{
$(this).css('cursor', 'pointer');
$("div.overlay").css('visibility','visible');
});
$("div.hover").mouseout(function ()
{
$(this).css('cursor', 'default');
$("div.overlay").css('visibility','hidden');
});
});
$("#id").mouseover(function(){
$("a[rel='#petrol']").overlay().load();
});
$("#id").mouseout(function(){
$("a[rel='#petrol']").overlay().close();
});

I am trying to get an animation effect where current content fades out, and is then replaced by content sliding in from the right side of the screen. My current effort:
http://jsfiddle.net/LKazq/3/
<p>header</p>
<div id="wrapper">
<div style="height: 400px; background-color: red;">
<p>Here is some text!</p>
<button id="next">And a button!</button>
</div>
</div>
<p>footer</p>
$('#next').click(function () {
var current = $('#wrapper :first-child');
var next = $('<div>').css("height", "400px").css("background-color", "blue");
next.hide();
current.fadeOut(800, function () {
current.remove();
$('#wrapper').prepend(next);
next.show("slide", { direction: "right" }, 800);
});
});
Two problems:
The removed element is still taking up space; notice how the footer gets pushed down.
Is there anyway to suppress the horizontal scroll bar?
Any tips on better ways to do this are appreciated. Thanks!
The reason for the vertical scroll back is because of an additional UI wrapper that jQuery UI puts in place.
You can do this with regular jQuery and it should be just fine:
$('#next').on('click',function(){
var wrapper = $('#wrapper'),
current = wrapper.children().first(),
next = $('<div>').css({
height:400,
backgroundColor:'blue',
marginLeft:'100%',
display:'none'
});
current.fadeOut(800, function () {
$(this).remove();
wrapper.prepend(next);
next.show().animate({marginLeft:0},800);
});
});
Updated jsFiddle.
That's the quick-fix way to do it. An additional step is to externalize your CSS into classes (which you really, really should do instead of inline styles) to make things a bit cleaner:
HTML:
<p>header</p>
<div id="wrapper">
<div class="first">
<p>Here is some text!</p>
<button id="next">And a button!</button>
</div>
</div>
<p>footer</p>
CSS:
wrapper {
overflow:auto;
overflow-x:hidden;
}
.first {
height:400px;
background-color:red;
}
.second {
height:400px;
background-color:blue;
}
Better jQuery:
$('#next').on('click',function(){
var wrapper = $('#wrapper'),
current = wrapper.children().first(),
next = $('<div>').addClass('second').css({
marginLeft:'100%',
display:'none'
});
current.fadeOut(800, function () {
$(this).remove();
wrapper.prepend(next);
next.show().animate({marginLeft:0},800,function(){
$(this).removeAttr('style');
});
});
});
Here is a second jsFiddle for that.
And finally the best (although not ancient-browser compliant) way to do it, by maximizing CSS.
CSS:
#wrapper {
overflow:auto;
overflow-x:hidden;
}
.first {
height:400px;
background-color:red;
}
.second {
height:400px;
background-color:blue;
margin-left:0;
-webkit-transition:margin-left 800ms;
-moz-transition:margin-left 800ms;
-o-transition:margin-left 800ms;
transition:margin-left 800ms;
}
.secondPushed {
margin-left:100%;
}
Smaller jQuery:
$('#next').on('click',function(){
var wrapper = $('#wrapper'),
current = wrapper.children().first(),
next = $('<div>').addClass('second secondPushed').hide();
current.fadeOut(800, function () {
$(this).remove();
wrapper.prepend(next);
next.show().removeClass('secondPushed');
});
});
This is the best from an overhead perspective, and its the way to do it in the modern web world, but it doesn't work on IE9 and below.
Here's a jsFiddle for that one.
I have created a customized menu. See here. On click of this link I have a shadowbox popping up which has a long list of items. Now I want to have a "back to top" anchor link which takes me back to the top of the menu list.
I've set your lightbox with the #box id.
Html
<div id="box">
...
<!-- long content there -->
To Top
</div>
CSS (setting the width of elements)
#box {
position:relative;
width:200px;
height:250px;
overflow:auto;
}
#box #toTop {
position:absolute;
display:none;
left:150px;
top:10px;
}
jQuery
$('#box').bind('scroll', function(e) {
if ($(this).scrollTop() > 100) {
$('#toTop').fadeIn();
$('#toTop').css({'top' : $(this).scrollTop() + 100});
} else {
$('#toTop').fadeOut();
}
});
$(document).on('click', '#toTop', function(e) {
e.preventDefault();
//$('#box').scrollTop(0); //just go to top
$('#box').animate({scrollTop : 0},'slow'); //animate
});
Fiddle
Pretty easy with:
document.querySelector("iframe").contentWindow.scrollTo(0,0);
Now put a button on the page and call that on click. Oh, and omit the height:100% on your body of the iframe, this way you get rid of the second scrollbar.
You can try this out by just pasting the line above and executing it in the console of your browser with your webpage.
I searched for this but didn't find an solution that totally fixed my problem.
I got 2 divs that are over each other. Where div #2 isn't shown (display:none).
Now what I want is that if I hover over div #1, div #2 slides down (open) at his current position.
Then div #2 should stay open when people are hovering over div #2, when they leave the hover status of div #2 for more then 5 seconds div #2 slides up again.
I made a fiddle to illustrate my div positions.
Using jQuery to keep the code simpler. One way to do what you want is to pair a global variable with a setTimeout function. The timeout checks if the mouse is still out of the div after five seconds, and if so, slides it up and out of sight.
$('.button').click(function() {
$('.showme').slideDown();
});
$('.showme').mouseout(function() {
window.isoverdiv = false;
setTimeout(function() {
if (!window.isoverdiv) {
$('.showme').slideUp();
}
}, 5000);
});
$('.showme').mouseover(function() {
window.isoverdiv = true;
});

I moved div #2 into div #1 and this allowed me to do this with only css
http://jsfiddle.net/57Shn/
CSS
.button {width:100px; height:50px; position:fixed; background-color:blue; margin-top:30px;}
.button:hover .showme {display:block}
.showme {width:100px; height:200px; position:fixed; background-color:red; display:none; margin-top:30px;}
HTML
<div class="button">
touch me
<div class="showme">show me</div>
</div>
CSS-only solution: (doesn't slide)
<div class="outer">
<div class="one">Hover</div>
<div class="two">Hello World!</div>
</div>
CSS:
.two { display: none; }
.outer:hover .two { display: block; }
JS solution:
$(function() {
$('.two').hide();
$('.outer').hover(function() { $('.two').stop().slideDown(); });
$('.outer').mouseout(function() { $('.two').stop().slideUp(); });
});
I am new to javascript and would like to have an image that is fully displayed but when you mouse over the image text appears over the top in a div tag and fades the image in the background.
This is my attempt however poor and it is not working.
<style>
/*CSS Style sheet*/
div.image_box_text {
opacity:0;
margin-top:-25px;
background-color:#FFF;
}
</style>
<script>
function fadeImg(obj) {
obj.style.opacity=0.5;
obj.filters.alpha.opacity=50;
}
function viewObj(obj1, obj2) {
fadeImg(obj1);
obj2.style.opacity=1;
bj2.filters.alpha.opacity=100;
}
</script>
<div>
<img id='img1' src="../images/index/square/posingS.jpg" onmouseover='viewImg(this, txt1)'/>
<div id='txt1' class='image_box_text' >This is image box one</div>
</div>
Thanks in advance.
This should get you started.
<style>
/*CSS Style sheet*/
div.image_box_text {
opacity:0;
margin-top:-25px;
background-color:#FFF;
}
</style>
<script>
function fadeImg(obj) {
obj.style.opacity=0.5;
}
function viewObj(obj1, obj2_name) {
var obj2 = document.getElementById(obj2_name);
fadeImg(obj1);
obj2.style.opacity=1;
}
</script>
First, you cannot simply call an object by an id as you did in viewObj. You must do a document.getElementById on its id. Next you will have to check if filters exists (it only does in IE). A better way to do this is to make .faded and .hidden classes in your stylesheet and have the hover event trigger the adding and removal of them.
Here's this code in action: http://jsfiddle.net/WpMGd/
I have a Div with position:relative which contains "one or more" images inside it with postion:absolute with some top and left values. I need to toggle the position attribute of ALL THE IMAGES at a time between Absolute and Auto/Relative with a button using JS or JQuery.
Is there any way to work with all these child IMAGES at a time?
try the following:
html
<div class="wrapper">
<img src="http://dummyimage.com/15x15/000/fff" class='absPosition'>
</div>
<input type="button" value="change position">
css
.wrapper {
height:300px;
position:relative;
}
.absPosition {
position:absolute;
bottom:0;
}
jQuery
$(":button").click(function() {
$("img").toggleClass("absPosition")
});
Demo: http://jsfiddle.net/ZRDdB/
Just use a jQuery selector which encompasses all of the images within your div. If, for example, your div had an id of "divId" then to set the position to relative of all the images within that div, you would use:
$(document).ready(function() {
$("#button").click(function() {
$("#divId img").css("position", "relative")
});
});
This would be best achieved using both CSS rules (as in CSS rules, not JS assigned inline styles) and jQuery's .toggleClass() method.
If you've got markup like the following:
<div id='foo'>
<img />
<img />
</div>
and CSS like the following:
div#foo { position:relative; }
div#foo img { position:relative; }
div#foo img.absolute { position:absolute; }
You can easily toggle that the IMGs' position rule using something like
$('button').click(function() {
$('div#foo img').toggleClass('absolute');
});
