Please see example in chrome. I try to implement row height animation with image that shouldn't exceed parent block.
Why does image width change only after changing any property example?
Try to click the first button, image height will updated, but width no. Then click the second button, opacity will changed, and image width will be setted properly.

function check(){
var classes = el.className.split(' '),
hasClass = classes.indexOf('header-row-reduced');
if(~hasClass) {
classes.splice(hasClass,1);
} else {
classes.push('header-row-reduced');
}
el.className = classes.join(' ');

function changeProp() {

Thats a good question. I don't know why this is not working like expected.
But you could fix it by applying the rule with the height to the element as well:
.header-row-reduced, .header-row-reduced img {
height:50px;
}
This works, but I'm sure it is not exactly what you want to have!
Setting max-height in pixels should fix the issue as well.

Anyone know how to resize an image up and down on click.
Example: nrk.no
The website you give as an example uses CSS Transitions to make some of their images grow and shrink. You can learn more about CSS Transitions at https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Transitions/Using_CSS_transitions
Below is a simple example using JQuery. When you click on the Google logo it will grow and when you click on it again it will shrink.
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<style>
.box img {
transition: width .4s,margin .4s,max-width .4s;
transition-property: width, margin, max-width;
transition-duration: 0.4s, 0.4s, 0.4s;
transition-timing-function: ease, ease, ease;
transition-delay: 0s, 0s, 0s;
}
.box img.clicked{
width: 500px;
}
</style>
<script>
$(function(){
$('.box img').on('click', function() {
$(this).toggleClass('clicked');
});
});

I try to make a little slider, but it works only in Google Chrome.
In FireFox (version 47) it doesn't work.
The CSS file is that:
#home-container {
width: 500px;
height: 300px;
background-image: url("img1.jpg");
background-repeat: no-repeat;
background-size: cover;
-webkit-transition: all 0.5s ease;
-moz-transition: all 0.5s ease;
-o-transition: all 0.5s ease;
transition: all 0.5s ease;
}
and the HTML (with a little script):
<!DOCTYPE html>
<html>
<head>
<title>CSS Slider</title>
<link rel="stylesheet" href="style.css"/>
<script>
var index = 0;
function changeImage() {
var imgArr = ['img1.jpg', 'img2.jpg', 'img3.jpg'];
document.getElementById("home-container").style.backgroundImage = "url('" + imgArr[index] + "')";
index++;
if (index >= imgArr.length) {
index = 0;
}
}
setInterval(changeImage, 2000);
</script>
</head>
<body>
<div id="home-container">
</div>
</body>
</html>
PS: I need a solution for that code, not an alternative to use jQuery.
Firefox won't support it according to this bug nor is it an animatable property (https://www.w3.org/TR/css3-transitions/#animatable-properties).
See this awswer for details.
Can u try to add transition-delay (4th parameter) equal 0, into all properties?
Maybe you can play with the opacity attribute. Check this: http://www.quirksmode.org/js/opacity.html is a way to set opacity in all elemnts.
I'm a beginner in javascript and I stumbled upon this problem.
This is a part of markup from site i'm working on:
<div class="row">
<div class="col-lg-12">
<div id="target">
<div id="bgDiv">
<img src ="someurl">
</div>
</div>
</div>
</div>
It's a part of a simple bootstrap layout. What i want to do is to animate the #target div so that the image fills the whole browser screen on mouseover , preferably using pure javascript. If I do it with this function:
function(){
var target = document.getElementById('target');
function FullScreen {
target.style.cssText ='position:absolute;top:0;bottom:0;left:0;right:0;z-index:999'
document.body.appendChild(target);};
target.addEventListener('mouseover', FullScreen)};
It does the job of displaying the image covering whole browser window, but I'm cluless how to make the "fill" animation. I tried experimenting with transitions, but i think since i change the 'position' property and append the element to body it does not work.
I would be grateful for any help or suggestions.
As Portal_Zii already mentioned, you can easy create animations without javascript using CSS3 properties only like:
transition
animation
With this knowledge its quiet simple to implement an hybrid solution with CSS3 transition property, the onmouseenter and onmouseleave event.
Try to run the Code and re-size the window.
var myDiv = document.getElementById("myDiv");
var myImg = document.getElementById("myImg");
myDiv.onmouseleave = shrinkImage;
myDiv.onmouseenter = growImage;
function shrinkImage() {
myImg.style.width = 50 + "px";
myImg.style.height = 50 + "px";
}
function growImage() {
myImg.style.width = window.innerWidth + "px";
myImg.style.height = window.innerHeight + "px";
}
img {
width: 50px;
height: 50px;
transition: all 0.7s;
}
<div id="myDiv">
<img id="myImg" src="data:image/gif;base64,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"

You can describe all of the target's element properties in the class 'over' of css and describe an animation through transition on properties of position of your element. Then when you this class 'over' to element with id=target.
function FullScreen {
target.style.classList.add('over')};
I think all you need to do is add transition styles in your css:
#target {
-webkit-transition: all .5s ease-in-out;
-moz-transition: all .5s ease-in-out;
-o-transition: all .5s ease-in-out;
transition: all .5s ease-in-out;
}
Additionally you could accomplish this in just using css no?
#target {
DEFAULT:STYLES;
-webkit-transition: all .5s ease-in-out;
-moz-transition: all .5s ease-in-out;
-o-transition: all .5s ease-in-out;
transition: all .5s ease-in-out;
}
#target:hover {
position:absolute;
top:0;
bottom:0;
left:0;
right:0;
margin:0;
padding:0;
z-index:999;
-webkit-transition: all .5s ease-in-out;
-moz-transition: all .5s ease-in-out;
-o-transition: all .5s ease-in-out;
transition: all .5s ease-in-out;
}
Does animation work if the block content is in state "none"?
For example, if I want to use Load with JQuery, and I want animation to start after the page load, will this work?
.container {
display : none;
}
.container .animate {
transform : translate(0,-100px);
transition : 1s transform ;
}
.show {
display : block ;
}
in jquery
$(function() {
$(".container").addClass("show");
});
If there is another way please help me.
Looks like display:none elements can be animated...
Here's a test : the text is hidden, translates to the right, then shows up : it works.
$("p").addClass("shift");
setTimeout( function(){
$("p").css("display","block");
}, 1000)
p{
display:none;
border:green solid 1px;
width:150px;
-webkit-transition: all 1s ease-in-out;
-moz-transition: all 1s ease-in-out;
-o-transition: all 1s ease-in-out;
transition: all 1s ease-in-out;
}
p.shift{
transform : translate(300px,0);
-webkit-transform: translate(300px,0);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<p>some text</p>
Is this what you want?
Just try to change the attr
$(function() {
$(".container").attr("display","block !important");
});
I am revealing an element using a CSS transition that is triggered by a JavaScript scroll event however this transition is affecting the background color of an adjacent element in Safari (5.1.7) and Chrome (27.0.1453.93) on a Mac (10.6.8) which makes no sense at all. I think I have stumbled upon a bug.
I duplicated the issue in Safari only using the following, stripped-down code and created a jsfiddle (http://jsfiddle.net/5AEMF/) but the issue does not occur within that framework:
<!DOCTYPE html>
<html lang="en-US">
<head>
<meta charset="utf-8">
<title>Opacity transition affecting color of adjacent element</title>
<style>
* {
margin: 0;
padding: 0;
}
#bar {
height: 100px;
background-color: #FF0000;
}
#content {
opacity: 0;
height: 9999px;
background-color: #0000FF;
-webkit-transition: opacity 0.25s ease-in-out;
-moz-transition: opacity 0.25s ease-in-out;
-o-transition: opacity 0.25s ease-in-out;
transition: opacity 0.25s ease-in-out;
-webkit-backface-visibility: hidden;
-moz-backface-visibility: hidden;
-o-backface-visibility: hidden;
backface-visibility: hidden;
}
#content.scrolled {
opacity: 1;
}
</style>
<script type="text/javascript">
var scrolled = false;
var init = function() {
onScroll(null);
window.addEventListener('scroll', onScroll);
};
var onScroll = function(e) {
if (window.scrollY > 0 && !scrolled) {
scrolled = true;
document.getElementById('content').className = 'scrolled';
} else if (window.scrollY === 0 && scrolled) {
scrolled = false;
document.getElementById('content').removeAttribute('class');
}
};
window.addEventListener('load', init);
</script>
</head>
<body>
<div id="bar"></div>
<div id="content"></div>
</body>
</html>
I wonder if there's a workaround for this issue. Any help would be greatly appreciated.
Use colors in RGB form eg: color:rgba(255, 106, 0, 0.24) the last parameter in this property 0.24 is an opacity. make it 0 and it will be transparent.
