I have tried and failed to get this working. Basically I am trying to get it so that when you hover over one div, it should change the sibling's opacity to 0.5 that has class="receiver".
If you see this jsFiddle, there are 2 divs with class="outerwrapper", and both contain 2 divs of classes hover and receiver. When you hover over the div with class hover, the receiver's opacity should be set to 0.5, but only the one inside the same div (outerwrapper).
Any help would be much appreciated. Thanks in advance.
You don't need to use jQuery, or JavaScript, for this (though you can1), CSS is quite capable in most browsers of achieving the same end-result:
.hover:hover + .receiver {
opacity: 0.5;
}
JS Fiddle demo.
And also, even with 'only' CSS, in modern/compliant browsers, it's possible to use fade transitions (or, strictly speaking, to transition the opacity):
.receiver {
width: 50px;
height: 50px;
background-color: blue;
opacity: 1;
-webkit-transition: opacity 1s linear;
-o-transition: opacity 1s linear;
-ms-transition: opacity 1s linear;
-moz-transition: opacity 1s linear;
transition: opacity 1s linear;
}
.hover:hover + .receiver {
opacity: 0.5;
-webkit-transition: opacity 1s linear;
-o-transition: opacity 1s linear;
-ms-transition: opacity 1s linear;
-moz-transition: opacity 1s linear;
transition: opacity 1s linear;
}
JS Fiddle demo.
I was going to provide a JavaScript/jQuery solution as well, but there are several others already posted, now, and I'd rather not repeat other people's answers in my own (it just feels like plagiarism/copying).
Something like this would do it: http://jsfiddle.net/UzxPJ/3/
$(function(){
$(".hover").hover(
function(){
$(this).siblings(".receiver").css("opacity", 0.5);
},
function(){
$(this).siblings(".receiver").css("opacity", 1);
}
);
});
References
.siblings() - Get the siblings of an element - http://api.jquery.com/siblings/
.hover() - Catch the mouseover/mouseout events - http://api.jquery.com/hover/
$('.hover').hover(function() {
$(this).next('.receiver').css('opacity', 0.5);
}, function() {
$(this).next('.receiver').css('opacity', 1.0);
});
http://jsfiddle.net/2K8B2/
(use .siblings or .nextAll if the .receiver is not necessarily the next element)
This works:
$(document).ready(function() {
$('.hover').hover(function() {
var $parent = $(this).parent('.outerwrapper');
$parent.find('.receiver').css({ opacity : 0.5 });
}, function() {
var $parent = $(this).parent('.outerwrapper');
$parent.find('.receiver').css({ opacity : 1 });
});
});

I am working on a new site that is using page transitions. The old content fades away and the new content fades in - at least that's what should happen.
When the new content is loaded, I use JS to set it's opacity: 0
this.newContainer.style.opacity = 0;
Then, I add a new class so I can use CSS transitions
this.newContainer.classList.add("animate-in");
This is the CSS for the .animate-in
.wrapper.animate-in {
opacity: 1;
visibility: visible;
-webkit-transition: all 1000ms ease-in-out;
-moz-transition: all 1000ms ease-in-out;
-ms-transition: all 1000ms ease-in-out;
-o-transition: all 1000ms ease-in-out;
transition: all 1000ms ease-in-out;
}
However, this doesn't work. The code doesn't animate the opacity from 0 to 1. Instead, it is animating backwards, from 1 to 0. It seems like the classList.add doesn't hear the previous line of code.
Anyone know how to fix this?
EDIT
OK, so I learned that using the JS style.opacity will completely override any opacity CSS rules. This is my problem. How do I get around this?
Try to use css animation and remove code--> this.newContainer.style.opacity = 0;
.wrapper.animate-in {
opacity: 1;
transition: all 1000ms ease-in-out;
animation: animate-in01 1s;
animation-iteration-count: 1;
}
#keyframes animate-in01{
0% {
opacity: 0;
}
100% {
opacity: 1;
}
}
I have the following in my script.js file:
$(document).ready(function(){
$( '.elementoBarra1').hover(
function(){
$(this).addClass('lineaBarraActive');
},
function(){
$(this).removeClass('lineaBarraActive');
}
);
});
There is a change in color (based on the instructions I'm giving in the stylesheet), but there's no animation (or transition). It just passes binarily to the other color, there's no animation where it passes through all the colors in the middle in a short-lapse of time.
Why is this?
EDIT: Just tried fadeIn() and fadeOut() and they are working properly, they have a smooth animation. Why are addClass() and removeClass() not working properly?
addClass and removeClass api of Jquery doesn't provide any animation. They are just meant for adding or removing class.
If you want to achieve animation, then you must add transition in the class you are adding.
There's no need for jQuery also. Just use :hover pseudo selector to achieve it
.elementoBarra1 {
background-color: black;
width: 100px;
height: 200px;
-webkit-transition: background-color 1s linear;
-moz-transition: background-color 100ms linear;
-o-transition: background-color 1s linear;
-ms-transition: background-color 1s linear;
transition: background-color 1000ms linear;
}
.elementoBarra1:hover {
background-color: red;
-webkit-transition: background-color 1s linear;
-moz-transition: background-color 100ms linear;
-o-transition: background-color 1s linear;
-ms-transition: background-color 1s linear;
transition: background-color 1000ms linear;
}

You can try j Query Animate.
$( "selector" ).animate({
width: "70%",
opacity: 0.4,
marginLeft: "0.6in",
fontSize: "3em",
borderWidth: "10px"
}, 1500 );
You can set css style as mentioned above so that you can get smooth animation.

I have a div that when you click on it opens up the the content within, at the top of the bar I have an arrow image that if the content is closed (default position) the arrow is pointing to the right and when the content is open I want the arrow image to rotate to pointing down.
I am using jQueryRotate to rotate the image and I have all the elements working, but what I can't get it to work when toggling, I can only get the image to rotate once when opening the content, I have where I have got to here
$("#ProductHeaderWrap1").click(function () {
$("#ProductDetailsToggle1").stop().slideToggle("slow");
});
$("#ProductHeaderWrap1").click(function () {
$("#ProductHeaderWrap1").find(".arrow").rotate({
animateTo: 90
}, {
duration: 500
});
});
http://jsfiddle.net/cgF4a/ along with some worked on jQuery attempts, I just need the image to rotate to 0 when clicked to close the div.
Thanks for any help,
J.
It's easier to do this with CSS, take a look:
img.open {
-webkit-transform:rotate(90deg);
-moz-transform:rotate(90deg);
transform:rotate(90deg);
-webkit-transition: -webkit-transform 1s linear;
-moz-transition: -moz-transform 1s linear;
-o-transition: -o-transform 1s linear;
transition: transform 1s linear;
}
img {
-webkit-transition: -webkit-transform 1s linear;
-moz-transition: -moz-transform 1s linear;
-o-transition: -o-transform 1s linear;
transition: transform 1s linear;
}
$(document).ready(function () {
$("#ProductHeaderWrap1").click(function () {
$("#ProductDetailsToggle1").stop().slideToggle("slow");
$(this).find("#Image1").toggleClass("open");
});
});
Updated JSFiddle
I have a table like this:
<div class="footer_row_3">
<table class="tableA">
<tr>
<td><img class="popcorn" src="http://i.imgur.com/HUjq2Va.png"></td>
<td><span class="statement">Lorem Ipsum</span></td>
<td><img class="popcorn" src="http://i.imgur.com/HUjq2Va.png"></td>
</tr>
</table>
</div>
What I want to do is that when the mouse hovers over tableA at any location within tableA, the following two changes happen:
Popcorn images change to this image: http://i.imgur.com/K29T3Fw.png
The text color changes to red.
It should have with a CSS 'fade' style transition, so that the contents fades into the updated style contents.
BOTH changes mentioned above should happen when I hover tableA from any place within tableA.
I know how to individually change text and image on hover, but I don't know how to do it together for multiple items.
How can I achieve this effect ?
Hover and change of other elements data/ styles is possible if the one element is the child of other
Here's a possible direction you can proceed and it works
#parent_element:hover > child_element {
//change your required styling or images
}
Heres the link
Hover to change
Try this:
CSS
span{
transition: color 2s ease;
}
.tableA:hover span{
color:red;
}
Plain Javascript (option 1)
document.getElementsByClassName('tableA')[0].onmouseover = function () {
var images = document.getElementsByClassName('popcorn');
console.log(images);
for (i = 0; i < images.length; i++) {
images[i].src = 'http://i.imgur.com/K29T3Fw.png'
}
};
Demo here
jQuery (option 2)
$('.tableA').hover(function () {
$('.popcorn').prop('src', 'http://i.imgur.com/K29T3Fw.png');
});
Demo here
EDIT:
New demo here
try this
table.tableA:hover span.statement {
color: red;
-webkit-transition: color 1s ease-in-out;
-moz-transition: color 1s ease-in-out;
-o-transition: color 1s ease-in-out;
-ms-transition: color 1s ease-in-out;
transition: color 1s ease-in-out;
}
table.tableA:hover img.popcorn {
opacity:0;
-webkit-transition: opacity 1s ease-in-out;
-moz-transition: opacity 1s ease-in-out;
-o-transition: opacity 1s ease-in-out;
-ms-transition: opacity 1s ease-in-out;
transition: opacity 1s ease-in-out;
}
table.tableA td:first-child, table.tableA td:last-child {
background: url('http://i.imgur.com/K29T3Fw.png');
}
for better control and getting rid of first-child and last-child add classes to the tds.
I'm trying to create a fade out / fade in effect with CSS3 animations. Here is my CSS :
#buttonright, #buttonleft{
-webkit-transition:opacity 0.5s linear;
-moz-transition:opacity 0.5s linear;
-o-transition:opacity 0.5s linear;
-ms-transition:opacity 0.5s linear;
transition:opacity 0.5s linear;
}
And the Javascript (i'm using jquery) :
$('#buttonleft').css("opacity","0");
$('#buttonright').css("opacity","0");
$('#buttonleft').css("opacity","1");
$('#buttonright').css("opacity","1");
It looks like the browser think it's stupid to set the opacity to 0 then to set it back to 1. Does someone has a possible solution ?
Thank you.
Edit: Regard yaki's answer for a pure CSS3 solution.
You're not giving the browser enough time to complete the transition. If you add a setTimeout to the latter statements, it should work.
Something like this:
$('#buttonleft').css("opacity","0");
$('#buttonright').css("opacity","0");
setTimeout(function(){$('#buttonleft').css("opacity","1");}, 5000);
setTimeout(function(){$('#buttonright').css("opacity","1");}, 5000);
Actually accepted solution is not CSS3 solution (it's still requires some javascript code). Please check the code below.
html:
<a id='buttonleft'>Button left</a>
<a id='buttonright'>Button right</a>
css:
#buttonleft, #buttonright {
text-align: left;
background: rgb(180,180,255);
opacity:0.5;
/* property duration timing-function delay */
-webkit-transition: opacity 500ms linear 100ms;
-moz-transition: opacity 500ms linear 100ms;
-o-transition: opacity 500ms linear 100ms;
transition: opacity 500ms linear 100ms;
}
#buttonleft:hover, #buttonright:hover {
opacity: 1.0;
}
something like this?
$('#button').hover(
function() {
$(this).animate({opacity: 0}, 500);
},
function() {
$(this).animate({opacity: 1}, 500);
}
);
You can use CSS3 animations now that it is more supported than when you asked the original question. I've created a jsFiddle showing how to do this on hover.
#keyframes demo {
from {
animation-timing-function: ease;
opacity: 1;
}
50% {
animation-timing-function: ease-in;
opacity: 0;
}
to {
animation-timing-function: ease-inout;
opacity: 1;
}
}
img:hover
{
animation-delay: 0s;
animation-duration: 2s;
animation-iteration-count: 1;
animation-name: demo;
}
