I know how to stack divs on top of divs by doing position:absolute for the parent and position:relative for the children, but how can I make a div "rise up" from another div? An example of what I want to achieve is here. Scroll to the bottom and hover your mouse over the artwork.
What you can do is absolute position that pop-up in a relative positioned box, for example:
<div class="featured-image">
<div class="caption">
<p>This is where your text goes</p>
</div>
</div>
Now that you have that, you'll want to make the caption invisible unless scrolled over. So, a simple way to do this with just CSS is:
.featured-image { position:relative; width:300px; height: 400px; }
.caption { position:absolute; bottom:0; display:none; }
.feature-image:hover > .caption { display:block; }
The last line makes it seen when you mouse-over the image.
Then you could animate it with jQuery easily. That appears to be what they're using.
$(document).ready(function(e) {
$(".caption").hide();
});
var show = function() {
$(".caption", this).stop(true, true).show(500)
};
var hide = function() {
$(".caption", this).stop(true, true).hide(500);
};
$(".featured-image").hover(show, hide);
HTMl
<div id="pic">
<div>
</div>
</div>
CSS
#pic {
position: relative;
background: yellow;
width: 100px;
height: 100px;
overflow: hidden;
}
#pic div {
position: absolute;
bottom: -50px;
background: black;
height: 50px;
width: 100px;
}
JQuery
$('#pic').hover(
function(){
$(this).find('div').stop(true, true).animate({
'bottom': '+=50'
}, 100);
},
function(){
$(this).find('div').stop(true, true).animate({
'bottom': '-=50'
}, 100);
}
);

Introduce yourself to jQuery and z-index.
http://api.jquery.com/slideDown/
The trick here is slidedown will make your top div slide down. The only thing that comes to my mind, is instead of expanding that bottom div up, do the opposite. Get the top div, and have it slide-up, while the other div is displayed behind it. It should give the appearance of the bottom div 'sliding-up'.
Note, sorry if this doesn't work. I'm actually not sure if you can get it to slide only halfway up instead of all the way...good luck though!
You don't need JS for that, just use css3 transitions.

I am trying to place a position: absolute div inside a scrolling div and make it stay on the left when scrolling left or right. This is because I want the div to move like one unit (when scrolling left, right, top, bottom). It's working great on screen that lower then 2K but on HD screens (ie. 2k, 3k, 4k...) the child div is jumping around and looks bad.
Is there a better way to do it? What change should I make to the CSS for HD screens?
#parent {
overflow: auto;
width: 100%;
height: 100%;
position: relative;
}
#child {
overflow: hidden;
width: 20%;
height: 100%;
z-index:1;
position: absolute;
}
<div id="parent">
<div id="child"></div>
</div>
$("#parent").on('scroll', function (event) {
$("#child")[0].style.marginLeft = this.scrollLeft+"px";
});
You can use jQuery's css function to set the value. And use the parent element as jQuery object to use scrollLeft() function:
$("#parent").on("scroll", function() {
$("#child").css("margin-left", $(this).scrollLeft() + "px");
});
But I would not use jQuery for this at all. Why not use a fixed position in css for this? Like in this example. It should not flicker on any screen.
I have several underlaying divs with hover effect. Sometimes I need to show modal dialog and all undelaying divs should be "disabled". This is done by placing semi-transparent high z-index div on top of them, but the problem is that hover effect on underlaying div stays until I move my mouse. Is there a way to "unhover" underlaying divs when overlaying semi-transparent div becomes visible?
Simplified exanple
HTML:
<div class="somediv"></div>
<div id="modal"></div>
CSS:
#modal {
z-index: 1000;
background:#000;
position:fixed;
top:0; left:0;
width:100%;
height:100%;
display: none;
opacity: 0.3;
}
.somediv {
position: absolute;
left: 20px;
top: 20px;
width: 100px;
height: 100px;
background-color: red;
}
.somediv:hover {
background-color: blue;
}
JS:
setTimeout(function(){
$("#modal").show();
}, 5000);
Hover over square and wait 5 seconds.
It should work: http://jsfiddle.net/rjLhj/
When you open a modal (in JS), just add a class to your .somediv ('.no-hover', for example). In CSS, change your .somediv:hover to .somediv:not(.no-hover):hover.
I don't know about compatibility... So, you should test :P
JS:
setTimeout(function(){
$("#modal").show();
$('.somediv').addClass('no-hover')
}, 2000);
CSS:
.somediv:not(.no-hover):hover {
background-color: blue;
}
Update:
http://caniuse.com/#feat=css-sel3
It works on IE9+, FF3.5+ and Safari3.1+... But you can use Attribute Selectors for reach the same result.
HTML:
<div class="somediv" data-nohover="0"></div>
<div id="modal"></div>
CSS:
.somediv[data-nohover="0"]:hover {
background-color: blue;
}
JS:
setTimeout(function(){
$("#modal").show();
$('.somediv').attr('data-nohover','1')
}, 2000);
Or better, add one class to your somediv ('hashover', for example), remove it on modal open and define your css like this:
.somediv.hashover:hover {...}
Unfortunately the browser wont pick up mouse events until the mouse is moved...
The best way to deal with this is to create a new class that overrides the hover behaviour and apply this at the same time as you show the modal.
I am working on javascript scroll. I have following html code
JSFIDDLE
<div class="wrapper">
<div class="red div current"></div>
<div class="blue div"></div>
<div class="green div"></div>
<div class="yellow div"></div>
</div>
In above code I have four div tags red, blue, green and yellow. All of them are position in following css.
html, body {
height: 100%;
}
.wrapper {
overflow: hidden;
height: 100%;
}
.div {
position: relative;
height: 100%;
}
.red {
background: red;
}
.blue {
background: blue;
}
.green {
background: green;
}
.yellow {
background: yellow;
}
In above html and css the red div tag is the current one which means user is seeing the red div tag on the screen. Now what I am trying to do is when user scroll over window once, then the next div tag i.e. blue will be animated and moved to the top and will become visible to the user whereas the red div tag will be behind the blue one. This same process goes for both green and yellow.
The problem is that when user scroll once then the div tag should animate however my current javascript code is keep reading the scroll and animating the div tags one after another. What I want is when user scroll once then scroll should be disabled until the blue div tag is animated. Then scroll should be enabled. Again when user scroll second time, the scroll should disable until the green div tag completes its animation. Same goes for yellow.
How can I achieve above?
Here is my javascript
$(window).on("scroll", function () {
var next = $('.current').next();
var height = next.outerHeight();
next.animate({top: '-=' + height}, 500, function () {
$(this).prev().removeClass('current');
$(this).addClass('current');
});
});
Please have a look on update JsFiddle
$(window).on("scroll", function () {
var next = $('.current').next();
var height = $('.current').outerHeight();
$('.current').prevAll().each(function(){
height += $(this).outerHeight();
});
next.animate({top: '-=' + height}, 500, function () {
$(this).prev().css('top','');
$(this).prev().toggleClass('current');
$(this).toggleClass('current');
});
});
The main reason your example wasn't working as expected is because you were relatively positioning the divs, and not moving them to the correct spot.
Working JSFiddle:
http://jsfiddle.net/seanjohnson08/rVVuc/6/
.wrapper {
overflow: hidden;
height: 100%;
position: relative;
}
.div {
position: absolute;
height: 100%;
width: 100%;
top: 100%;
}
.current{
top: 0;
}
If you are looking for a way to limit the amount of scroll events fired, try throttling: http://benalman.com/projects/jquery-throttle-debounce-plugin/. My solution doesn't require this, because no matter how many times it is firing the scroll event, it only ever tells jquery to animate to top:0, there's no chance of it animating past that.
got a code here from someone....
what I like is to make the sliding div from right slide to left, i mean it hides the div to the right and slowly slides to the left for 300px width.
HTML
<a id="loginPanel">quote</a>
<div id="userNav">User Area</div>
CSS
#loginPanel {
color: #000;
cursor:pointer;
}
#userNav {
width: 200px;
height: 200px;
display: none;
background: #ff0000;
}
Jquery
// Open / Close Panel According to Cookie //
if ($.cookie('panel') == 'open'){
$('#userNav').slideDown('fast');
} else {
$('#userNav').slideUp('fast');
}
// Toggle Panel and Set Cookie //
$('#loginPanel').click(function(){
$('#userNav').slideToggle('fast', function(){
if ($(this).is(':hidden')) {
$.cookie('panel', 'closed');
} else {
$.cookie('panel', 'open');
}
});
});
Please need help on this one. just to make the div slide right to left
here is the fiddle http://jsfiddle.net/7m7uK/195/
You can use jQueryUI and additional effects Slide
http://docs.jquery.com/UI/Effects/Slide
Example:
$('#userNav').hide("slide", {direction: "left" }, 1000);
$('#userNav').show("slide", { direction: "right" }, 1000);
You can't use .slideToggle() to slide from left to right or vice versa, from http://api.jquery.com/slideToggle/:
The .slideToggle() method animates the height of the matched elements.
This causes lower parts of the page to slide up or down, appearing to
reveal or conceal the items. If the element is initially displayed, it
will be hidden; if hidden, it will be shown.
You should try and change your code to implement this code, but I think it's maybe better if you try with #s15199d answer, than you don't need to use jQueryUI
Ok, I created jsfiddle, you must include jQueryUI in order to work, you have different combinations of slide directions:
http://jsfiddle.net/7m7uK/197/
Ok, created another fiddle with cookies
http://jsfiddle.net/7m7uK/198/
Without depending on JQuery-UI
You need to place the content <div> you mean to slide inside a wrapper <div>. You then set the right margin of the content div to its negative width. The trick with the wrapper <div> is to have its x-overflow set to hidden so that it hides the content <div>. You can then use jQuery's native animate() routine to set the right margin to 0 to make the content <div> appear with a horizontal sliding effect.
HTML:
<div id="slider-wrapper">
<div id="slider-content">
</div>
CSS:
#slider-wrapper {
overflow-x: hidden;
}
#slider-content {
width: 300px;
margin-right: -300px;
}
JavaScript:
$("#slider-button").click(function () {
$("#slider-content").animate({ "margin-right": 0 }, "slow");
});
Here's a demo that uses a handle <div> to expand and collapse a div:
http://jsfiddle.net/gingi/KUCaL/
SLIDE DIV FROM RIGHT TO LEFT AND LEFT TO RIGHT
<div class="nav ">
<ul>
<li>HOME</li>
<li>ABOUT</li>
<li>SERVICES</li>
<li>CONTACT</li>
</ul>
</div>
CSS:
/*nav*/
.nav{
position: fixed;
right:0;
top: 70px;
width: 250px;
height: calc(100vh - 70px);
background-color: #333;
transform: translateX(100%);
transition: transform 0.3s ease-in-out;
}
.nav-view{
transform: translateX(0);
}
JS:
$(document).ready(function(){
$('a#click-a').click(function(){
$('.nav').toggleClass('nav-view');
});
});
http://www.themeswild.com/read/slide-navigation-left-to-right
$("#DivName").animate({"left": "-=300px", "opacity":1}, "slow");
Have you tried this ?
if ($.cookie('panel') == 'open'){
$('#userNav').slideLeft('fast');
} else {
$('#userNav').slideRight('fast');
}
I have a div which currently has a static background image.
I need to create a slideshow of background images for this div.
I am able to achieve this by just setting a timeout and then changing the background image in the CSS but this is not very elegant.
I would ideally like to fade the background images out and in, but the div contains other page elements so I can not alter the opacity in any way.
Does anyone know of a good way to do this using jquery??
Here's some code which fades out/in but fades out the contents of the div too.
$("#slideshow").fadeOut(5000, function(){
$("#slideshow").css('background-image','url(myImage.jpg)');
$("#slideshow").fadeIn(5000);
});
HTML:
<div class="slideshow"></div>
CSS:
.slideshow
{
position: relative;
width: 350px;
height: 150px;
}
.slideshow img
{
position: absolute;
width: 350px;
height: 150px;
z-index:-1;
}
jQuery
var images=new Array('http://placehold.it/250x150','http://placehold.it/250x150/123456','http://placehold.it/250x150/dbca98');
var nextimage=0;
doSlideshow();
function doSlideshow()
{
if($('.slideshowimage').length!=0)
{
$('.slideshowimage').fadeOut(500,function(){slideshowFadeIn();$(this).remove()});
}
else
{
slideshowFadeIn();
}
}
function slideshowFadeIn()
{
$('.slideshow').prepend($('<img class="slideshowimage" src="'+images[nextimage++]+'" style="display:none">').fadeIn(500,function(){setTimeout(doSlideshow,1000);}));
if(nextimage>=images.length)
nextimage=0;
}

How about adding a thumbs pagination list, to update the background image on click, and then, a second or two, and it starts fading in and out with the next bg img automatically?

Instead of just changing the background image, you could first call
fadeOut()
then change source, and then call
fadeIn()
something like...
$('#image').fadeOut(500, function() {
$(this).attr('src', 'new-image.png')
.load(function() {
$(this).fadeIn();
});
});
To use a variety of images, there are a number of solutions, but you could simply iterate through a list of them.
You can create an positioned absolutely and with a slider plugin change the images contained in the div. Otherwize you have to sprite the background. I achieved this with the Jquery Tools tabs plugin.
$(".slidetabs").tabs(".images > div", {
// enable "cross-fading" effect
effect: 'fade',
fadeOutSpeed: "slow",
// start from the beginning after the last tab
rotate: true
// use the slideshow plugin. It accepts its own configuration
}).slideshow();
Here is a solution that not only addresses your problem, but will also solve some other problems as well. Create another DIV on your DOM as an overlay, and execute your fade functions on this DIV only. It will appear as though the content is fading in / out. This approach is also more performant, as you are only fading a single DIV instead of multiple elements. Here is an example:
$('#containeroverlay').width($('#container').width()).height($('#container').height()).fadeIn('normal', function() {
// Step 1: change your content underneath the hidden div
// Step 2: hide the overlay
$('#containeroverlay').fadeOut('normal');
})
Most importantly, this approach will work in IE6-8 without screwing up the font aliasing of elements you may have on the div.
