i really want to know how this effect is created.
check this video, only 12 secs.
https://youtu.be/cJqU8jW0xsg
i try with :
.zoom {transform:scale(0.1); }
.zoom:hover {transform:scale(2); }
how to make it start from (top-left) and will end at (bottom-right) just like that in the video?
thanks in advance..
What you're after is the transform-origin property.
Here's an example.
http://codepen.io/dropkick/pen/YqKzdG/
HTML
<div class="box"></div>
<button>click me</button>
CSS
.box {
background: #0f0;
width: 200px;
height: 200px;
margin: 20px auto;
transition: transform 0.5s linear;
transform-origin: top right;
transform-style: preserve-3D;
transform:scale(0.1);
}
.box-scale {
transform:scale(1.0);
}
button {
display: block;
margin: auto;
}
JS
$('.scale').click(function () {
$('.box').toggleClass('box-scale');
});
You need transform-origin! https://developer.mozilla.org/en/docs/Web/CSS/transform-origin
Setting the origin sets the start point for the transition. It'll grow out from there.

I'm trying to add a cool little opacity transition for my extension. I've looked up many ways to go about this, and nothing has seemed to work so far. Is this even possible? I have the latest version of Chrome.
A preview of it not working
CSS:
.container .primary:after {
opacity: 0;
transition: opacity 6s ease-out;
}
.container .primary:hover:after {
opacity: 1;
content: "Go through a list of friends to remove";
position: absolute;
top: 100%;
width: 100vw;
height: 20px;
margin: 10px;
font-size: 13px;
}
It's hard to reproduce from your code but there's a few main problems:
Your pseudo element has top:100% so it's probably hanging off the bottom of the screen somewhere. You can use position:relative on the container to prevent this.
It's a bad idea to put text into pseudo elements. As another commenter pointed out, they can't be picked up by screen readers. Here's an in-depth article on the w3 website about this.
You absolutely do not want to transition something for 6 seconds! Try to stick to half a second maximum or your UI will feel slow. Here's a great writeup on the subject.
And finally, a full snippet combining the above suggestions. This is not perfect by any means, but it should be enough to get you started:
.container {
position: relative;
padding:10px;
font-family:'Arial';
border:1px solid black;
}
.container .tooltip {
opacity: 0;
transition: opacity 0.4s ease-out;
position: absolute;
top: 100%;
left: 0;
height: 20px;
padding:10px;
font-size: 13px;
}
.container .primary:hover .tooltip {
opacity: 1;
}
<div class="container">
<div class="primary">div
<div class="tooltip">"Go through a list of friends to remove"</div>
</div>
</div>
I have a basic setup. When I increase the height, I get a smooth increase. When decreased, I should get a smooth decrease but instead a sharp decrease.
<div className="foo <!-- -->">Hey</div>
You may have noticed className and <!-- -->, I'm using react. <!-- --> gets replaced with the class to decrease the height.
// SCSS
.foo {
height 400px;
// background props
transition: all 250ms ease-out
}
.foo.decreaseClass {
height: 40px;
transition: all 250ms ease-in
}
When the new class is attached, the div becomes
<div className="foo decreaseClass">Hey</div>
How to get both transitions down/up?
It's because you're not properly closing the height declaration in .foo. You're using a comma instead of a semi-colon, rendering both height and transition declarations invalid. Also note the same declaration should contain a colon between the style property name and its value (height: 400px;).
Therefore, your element only has defined height and transition only when having both classes.
See it working:
document.querySelector('.foo').addEventListener('click', function(event) {
event.target.classList.toggle('decreaseClass')
})
.foo {
height: 200px;
transition: all 250ms ease-out;
border: 1px solid
}
.foo.decreaseClass {
height: 40px;
transition-timing-function: ease-in
}
<div class="foo">Hey</div>
Use CSS #keyframe animation and alternate properties. infinite is added just for demo purposes. Instead of height I added transform:scaleY(1) to (10).
Demo
body {
overflow: hidden
}
.test {
width: 200px;
margin: 10px;
background: red;
font-size: 32px;
text-align: center;
color: white
}
.B {
height: 40px;
animation: animB 1s alternate infinite;
transform-origin: top;
}
#keyframes animB {
0% {
transform: scaleY(1);
}
100% {
transform: scaleY(10);
}
}
<div class='test B'>TEST</div>
.box {
width: 100px;
height: 100px;
background: red;
transition: all 1s ease-in-out;
}
.box:hover {
background: yellow;
}
<div class="box"></div>
If the cursor is over the .box for less than a second, the transition stops and falls back to it's original phase.
Is there a way to somehow force the whole animation, regardless of hover duration?
fiddle
Edit: Similar solution but relying on transition and animation: https://jsfiddle.net/ok7pnrsL/
This is my solution: https://jsfiddle.net/9yu0cozq/1/
Basically you need to add a container for the box and then play with CSS animations.
<div id="container">
<div class="box"></div>
</div>
When the mouse enters the .box then the hidden container appears (please note that for this to work that container should have enough width and height to fit the whole area where the mouse might go).
This container creates an animation for itself to "hide" back in 1s. and while it is shown the .box has an animation for the same time.
#container {
position:absolute;
z-index:1;
width: 0;
height: 0;
}
#container:hover{
animation-name:changeSize;
animation-duration: 1s;
}
#container:hover .box{
animation-name:changeColor;
animation-duration: 1s;
}
.box {
z-index:0;
position:absolute;
width: 100px;
height: 100px;
background: red;
transition:1s background;
}
.box:hover {
background: yellow;
}
#keyframes changeColor {
0% {
background: red;
}
100% {
background: yellow;
}
}
#keyframes changeSize {
0%,99% {
width: 100%;height: 100%;
}
100% {
width: 0;height: 0;
}
}
So, without knowing the real context, this solution gives a series of assumptions that might or might not fit your exact case but gives an idea of how to solve it using pure CSS.
I think you heave to use JS for this. First you need to create animation for background change, and and then you can set it as class and add that class on hover, and remove it when animation ends or on webkitAnimationEnd.
$('.box').hover(function() {
$(this).addClass('animate');
$(this).on('webkitAnimationEnd', function() {
$(this).removeClass('animate');
})
})
.box {
width: 100px;
height: 100px;
background: red;
display: inline-block;
margin: 10px;
}
.box.animate {
animation: changeColor 2s linear;
}
#keyframes changeColor {
0% {
background: red;
}
50% {
background: yellow;
}
100% {
background: red;
}
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="box"></div>
<div class="box"></div>
I don't think you can do this without javascript, but it would be interesting to find out.
A light weight javascript solution could be something like this:
// Get the elemnt
var myDiv = document.getElementById('box');
// Detect hover
myDiv.onmouseover = function() {
// Add a force class to the element
myDiv.className += " force";
// Reset the cass name after 1sec (100ms)
setTimeout(function(){ myDiv.className = "box"; }, 1000, myDiv);
}
Change your markup slightly to make things easier for now:
<div id="box" class="box"></div>
And add an extra class to your css styles along with the hover state:
.box {
width: 100px;
height: 100px;
background: red;
transition: all 1s ease-in-out;
}
.box.force,
.box:hover {
background: yellow;
}

I have a wordpress website and I'd like to add some features that my current theme doesn't offer. I'd like the 3 images in the "Pages" section to reduce in size or switch to a different image (same content, smaller resolution) so as to appear smaller then you hover over it. I've managed to accomplish this with a custom HTML page, adding ID's to the images and then adding a version of this to my style.css for each image
#techbutton {
display: block;
width: 125px;
height: 125px;
background: url("http://rafsk.co.uk/wp-content/uploads/2015/10/Logo21-e1445171629993.png") no-repeat 0 0;
}
#techbutton:hover {
background: url("http://rafsk.co.uk/wp-content/uploads/2015/10/Logo2-hover-e1445296643552.png") no-repeat 0 0;
}
#techbutton span {
position: absolute;
top: -999em;
}
After uploading the custom HTML to my server I realised that instead of just overriding the homepage of rafsk.co.uk it also overrode the homepages of all my subdomains.
So how can I do this?
You could do this with a css transform, that would be the easiest way, and you can apply it to all three with a class instead of an id (which should only be used once per page):
So first give the same class to all of the images (meaning to the actual image tag, like <img class="imageclass" src="blah.png" />), and use this in your css:
.imageclass {
display: block;
width: 125px;
height: 125px;
transform: scale(1,1);
}
.imageclass:hover {
transform: scale(0.9,0.9);
}
You could then add a css transition effect if you want it to be smoother:
.imageclass {
display: block;
width: 125px;
height: 125px;
transform: scale(1,1);
transition: transform 0.6s ease-in-out;
}
.imageclass:hover {
transform: scale(0.9,0.9);
}
Here is a working example:
https://jsfiddle.net/f9teea7L/
ALTERNATIVE OPTION #1:
If you can't edit the HTML and can only get an image into the div through the background, you could try adding a background-size property like this. Be aware though that it won't work in IE 8 or lower:
#techbutton {
display: block;
background-image: url('http://vignette1.wikia.nocookie.net/deadliestfiction/images/d/d5/2138464123_1360632315.jpg/revision/latest?cb=20140513035922');
background-size: 100%,100%;
width: 125px;
height: 125px;
transform: scale(1,1);
transition: transform 0.6s ease-in-out;
}
#techbutton:hover {
transform: scale(0.9,0.9);
}
Working Example: https://jsfiddle.net/azx962a9/
ALTERNATIVE OPTION #2:
I've looked at your site though and if I'm understanding what you want to do, it seems to me that simply adding this to your css should work...:
.service-icon {
transform: scale(1,1);
transition: transform 0.6s ease-in-out;
}
.service-icon:hover {
transform: scale(0.9,0.9);
}
I have been trying to design a login form and the button requires a little transition effect. There is one complexity though.
Background: I originally copied this idea from here: original form.
Notice how there is no padding (left and right) on the main container, now in my demo it was critical to have padding left and this creates a problem (will explain further).
Now here's my demo:
My version of login form (don't be scared of the 108 lines of CSS code; I'll paste the code that pertains to my problem below).
So the code that's relevant to this problem is as follows.
The HTML code:
<button class="login-button"><span>SEND</span></button>
The CSS code:
.login-button{
width: 100%;
outline: none;
border:none;
cursor: pointer;
padding: 0;
margin:0;
transition:.3s;
}
.login-input , .login-button{
height: 50px;
line-height: 40px;
transition:.3s;
}
.login-button span{
display: block;
background:red;
height: 100%;
width: 100%;
left: 0;
transition:.3s;
position: relative;
}
.login-button span:before{
content: 'ok';
position: absolute;
left: 100%;
display: block;
}
.login-button:hover span:before{
content: 'OK To go now';
position: absolute;
/*left: 0%;*/
text-align: center;
display: block;
width: 100%;
height: 100%;
}
Now if I go to the CSS styling for the main container:
I.E.
.main-login{
min-width: 200px;
max-width: 400px;
background: #533e69;
margin: 100px auto;
text-align: center;
overflow: hidden;
box-shadow: 1px 1px 10px rgba(0,0,0,.2);
padding: 0 20px;
}
and take off the padding, then the problem is solved and the transition looks perfect.
The problem
My requirements are such that I need that padding, so now what happens is when you hover over the button and the span element moves left:-100%, it's still visible in the main container.
Proposed solution
I would like it if this problem can be solved in CSS only as I don't really like cluttering my doc's with JS. So how about this.
I am new to CSS, so my solution may be less elegant:
When hovered over the button, the span overs left:-100% and than if the span can be set to display:none. Sounds simple, but my limited knowledge of CSS has got me stuck here.
You need to set the background to be transparent. It's not possible for a transition to animate the display property.
Add this css code, and it should work:
.login-button:hover span{
-webkit-transition-delay: 1s; /* Safari */
transition-delay: 1s;
transition: 2s;
background: rgba(1,1,1,0);
}
See your updated fiddle here.
Edit: I cleaned up the css a bit:
.login-button:hover span{
transition: 0.3s;
background: transparent;
}
Fiddle is here.
Transition properties are comma delimited in all browsers that support transitions:
.nav a {
-webkit-transition: color .2s, text-shadow .2s;
/* And so on... */
}
Ease is the default, so you don't have to specify it. If you really want linear, you will need to specify it, i.e. -webkit-transition: color .2s linear, text-shadow .2s linear;
Or try this
transition-property: width;
transition-duration: 1s;
transition-timing-function: linear;
transition-delay: 2s;
