I've just got a problem making the CSS3 animations.
I've written the following code:
#-webkit-keyframes menu_styling_hover
from
{
border-bottom-color:#F5B7B8;
padding-top:0px;
padding-bottom:0px;
}
to
{
border-bottom-color:#FB7A7D;
padding-top:6px;
padding-bottom:6px;
}
}
And I've attached this keyframe to the div with hover effect;
-webkit-animation:menu_styling_hover 0.3s linear;
animation:menu_styling_hover 0.3s linear;
It works fine. But when I unhover the element - it becomes to have previous characteristics without any animation of hiding it. So when the div is hovered, it has paddings 6px, and when I move mouse from this div - paddings become 0px without making animation (5..4..3..2..1). How to do such thing?
It seems like you are after a CSS transition as opposed to an animation.
Just set the initial styling, and change it when hovering over the element like so:
Example Here
.element {
height:40px;
border: 2px solid;
border-bottom-color:#F5B7B8;
padding-top:0px;
padding-bottom:0px;
transition: all 0.3s linear;
}
.element:hover {
border-bottom-color:#FB7A7D;
padding-top:6px;
padding-bottom:6px;
}

On my website I have a second header that drifts down from the top when the user scrolls down the page. The original header remains absolutely positioned at the top and is scrolled out of sight as the second slides down.
Due to the Google Chrome bounce scroll effect, if the user scrolls up when the browser is already at the top of the page, they're able to see the second header hanging around outside the document. This looks very strange, and it only happens in Chrome.
I've been trying to make the second header invisible when the user scrolls back to the top and it slides back out of view. I have been attempting to do this with an opacity value of 0 set with an ease value. The problem is, I am using transform:translate3d to animate the slide-up / slide-down effect, and I can't get both opacity and transform to work in the same transition rule.
Ideally I'd like the following to work, but it won't for some reason.
.hidden-header {
position:fixed;
transform:translate3d(0,-100%,0);
background-color:red;
width:100%;
height:55px;
opacity:0;
transition: translate 0.3s, opacity 0s ease .3s;
}
body.header-dropdown .hidden-header {
transform:translate3d(0,0,0);
opacity:1;
transition: translate .5s, opacity 0s;
}
Here is a jsFiddle to show you what I mean – https://jsfiddle.net/wbmm0kL7/2/
At the moment I have had to set it to transition: all .3s which means that the opacity fades in and out as well, which I want to avoid.
Here is a picture of my website with the problem on Chrome I am trying to solve. Notice that the second header and the nav menu are visible when scrolling against the edge of the viewport/document.
Here is the rest of my code:
HTML
<header class="header">REGULAR HEADER</header>
<div class="transform-container">
<div class="hidden-header">HIDDEN HEADER (SLIDES DOWN ON SCROLL)</div>
</div>
<div class="content"></div>
</div>
CSS
html,
body {
height:100%;
width:100%;
margin:0;
padding:0;
}
.wrapper {
background-color:orange;
min-height:100%;
}
.header {
position:absolute;
width:100%;
height:55px;
background-color:pink;
}
.hidden-header {
position:fixed;
transform:translate3d(0,-100%,0);
background-color:red;
width:100%;
height:55px;
opacity:0;
transition: all .3s;
}
body.header-dropdown .hidden-header {
transform:translate3d(0,0,0);
opacity:1;
transition: all .5s;
}
.content {
height:2000px;
}
jQuery
jQuery(document).ready(function($) {
$(window).scroll(function() {
if ($(this).scrollTop() > 200) {
$('body').addClass('header-dropdown');
} else {
$('body').removeClass('header-dropdown');
}
});
});
As per my comment, you have a typo in your CSS transitions rule. You cannot transition individual transform components. Instead, use transition: transform 0.5s; for example.
To achieve the effect of the hidden header appearing immediately, you set the transition duration of opacity to 0s when .header-dropdown is added. To achieve the effect of the hidden header hiding after the transform is done transitioning, you set the transition delay of opacity to the transition duration used:
.hidden-header {
position:fixed;
transform:translate3d(0,-100%,0);
background-color:red;
width:100%;
height:55px;
/* Delay opacity transition when returning to ground state */
transition: transform 0.5s, opacity 0s 0.5s;
opacity: 0;
}
body.header-dropdown .hidden-header {
transform:translate3d(0,0,0);
opacity: 1;
transition: transform 0.5s 0s, opacity 0s;
}
See your fixed fiddle here: https://jsfiddle.net/teddyrised/wbmm0kL7/3/
Note that the first numeric value of the transition shorthand is always the transition-duration, while the second numeric value is the transition-delay
I am a beginner in this and I am working on my new website. But I am stuck at one point where I want the effect that will make my links fade into images. I am having a navigation-bar on top of my page and when I hover over the link, I want the text to fade out at the same time as a small logo is fading in. And when I hover out of the link I want the image to fade out at the same time as the lin is fading back in, you know?
But when I do this, the image just pops up and fades out at the same time as the link is fading out...
#navigation a[name="project"] {
-webkit-transition: opacity 1s ease-in-out;
-moz-transition: opacity 1s ease-in-out;
-o-transition: opacity 1s ease-in-out;
transition: opacity 1s ease-in-out;
}
#navigation a[name="project"]:hover {
opacity:0;
background-image:url(bilder/project.png)
}
The image is the background for the element you're fading out, so it will also fade on hover. You'll need to separate the image into a separate element.
Perhaps you could use absolute positioning inside a container to have the text cover up the image, and then when the text is hovered over, it'll fade out, revealing the image underneath.
A working example of this is at http://jsfiddle.net/y9aw7/
HTML:
<div id="container">
Example Text
<img src="http://placekitten.com/100/100" />
</div>
CSS:
#container {
position: relative;
}
a, img {
position: absolute;
left: 0;
top: 0;
height: 100px;
width: 100px;
}
a {
z-index: 1;
line-height: 100px;
text-align: center;
background-color: #fff;
-webkit-transition: 0.4s opacity;
-moz-transition: 0.4s opacity;
-o-transition: 0.4s opacity;
-ms-transition: 0.4s opacity;
transition: 0.4s opacity;
}
a:hover {
opacity: 0;
}
Edit: Further jsfiddle, forked from the fiddle provided by the OP, with corrected CSS: http://jsfiddle.net/JmwdC/1
Try this :
Demo
CSS
#gl{
position:absolute;
left:0px;
width:100px;
height:30px;
opacity:0;
transition:all 0.5s;
}
#gl:hover{
opacity:1;
}
HTML
<!DOCTYPE html>
<html>
<head>
<meta charset=utf-8 />
<title>JS Bin</title>

</html>
You can use any property you want to achieve this, except display which does not work with CSS3 transition.
The most common techniques make use of
opacity (to 0)
height (to 0)
z-index (to negative / lower value than the container)
Sticking to your example, you can do it by using an background-image in <li>, and changing the opacity to the <a>, no changes to your HTML are needed.
Demo: http://jsfiddle.net/D6wuH/2/
Relevant CSS
li {
/* ... other stuff... */
background:none no-repeat scroll center center ;
}
#navigation li, #navigation li > a{
transition: all 1s ease-in-out;
}
#navigation li > a{
background: white;
}
#navigation li:hover {
background:url(http://dareminnesota.com/images/facebook-like-button.png)
no-repeat scroll center center transparent;
}
#navigation li:hover > a {
opacity: 0;
}
Playing with the difference between the initial state and the hover state of a lot of properties (was X, on hover becomes Y; wasn't there, on hover it's there; was there, on hover it's not there anymore) will let you achieve a world of different results, with weird effects like this: http://jsfiddle.net/D6wuH/0/ :)
Is there any way to do the opposite of :hover using only CSS? As in: if :hover is on Mouse Enter, is there a CSS equivalent to on Mouse Leave?
Example:
I have a HTML menu using list items. When I hover one of the items, there is a CSS color animation from #999 to black. How can I create the opposite effect when the mouse leaves the item area, with an animation from black to #999?
jsFiddle
(Have in mind that I do not wish to answer only this example, but the entire "opposite of :hover" issue.)
If I understand correctly you could do the same thing by moving your transitions to the link rather than the hover state:
ul li a {
color:#999;
transition: color 0.5s linear; /* vendorless fallback */
-o-transition: color 0.5s linear; /* opera */
-ms-transition: color 0.5s linear; /* IE 10 */
-moz-transition: color 0.5s linear; /* Firefox */
-webkit-transition: color 0.5s linear; /*safari and chrome */
}
ul li a:hover {
color:black;
cursor: pointer;
}
http://jsfiddle.net/spacebeers/sELKu/3/
The definition of hover is:
The :hover selector is used to select elements when you mouse over
them.
By that definition the opposite of hover is any point at which the mouse is not over it. Someone far smarter than me has done this article, setting different transitions on both states - http://css-tricks.com/different-transitions-for-hover-on-hover-off/
#thing {
padding: 10px;
border-radius: 5px;
/* HOVER OFF */
-webkit-transition: padding 2s;
}
#thing:hover {
padding: 20px;
border-radius: 15px;
/* HOVER ON */
-webkit-transition: border-radius 2s;
}
The opposite is using :not
e.g.
selection:not(:hover) { rules }
Just use CSS transitions instead of animations.
A {
color: #999;
transition: color 1s ease-in-out;
}
A:hover {
color: #000;
}
Live demo
Put your duration time in the non-hover selection:
li a {
background-color: #111;
transition:1s;
}
li a:hover {
padding:19px;
}
Just add a transition to the element you are messing with. Be aware that there could be some effects when the page loads. Like if you made a border radius change, you will see it when the dom loads.
.element {
width: 100px;
transition: all ease-in-out 0.5s;
}
.element:hover {
width: 200px;
transition: all ease-in-out 0.5s;
}
No there is no explicit property for mouse leave in CSS.
You could use :hover on all the other elements except the item in question to achieve this effect. But Im not sure how practical that would be.
I think you have to look at a JS / jQuery solution.
Another way of using transition is just specifying the milliseconds like so: transition: 500ms;
Try the following snippet
div{
background: DeepSkyBlue;
width:150px;
height:100px;
transition: 500ms;
}
div:hover{
opacity: 0.5;
cursor:pointer;
}
<div>HOVER ME</div>
You can use CSS3 transition
Some good links:

http://www.alistapart.com/articles/understanding-css3-transitions/
Just add a transition and the name of the animation on the class inicial, in your case, ul li a, just add a "transition" property and that is all you need
ul li {
display: inline;
margin-left: 20px;
}
ul li a {
color: #999;
transition: 1s;
-webkit-animation: item-hover-off 1s;
-moz-animation: item-hover-off 1s;
animation: item-hover-off 1s;
}
ul li a:hover {
color: black;
cursor: pointer;
-webkit-animation: item-hover 1s;
-moz-animation: item-hover 1s;
animation: item-hover 1s;
}
#keyframes item-hover {
from {
color: #999;
}
to {
color: black;
}
}
#-moz-keyframes item-hover {
from {
color: #999;
}
to {
color: black;
}
}
#-webkit-keyframes item-hover {
from {
color: #999;
}
to {
color: black;
}
}
#keyframes item-hover-off {
from {
color: black;
}
to {
color: #999;
}
}
#-moz-keyframes item-hover-off {
from {
color: black;
}
to {
color: #999;
}
}
#-webkit-keyframes item-hover-off {
from {
color: black;
}
to {
color: #999;
}
}
<ul>
<li><a>Home</a></li>
<li><a>About</a></li>
<li><a>Contacts</a></li>
</ul>
Although answers here are sufficient, I really think W3Schools example on this issue is very straightforward (it cleared up the confusion (for me) right away).
Use the :hover selector to change the style of a button when you move
the mouse over it.
Tip: Use the transition-duration property to determine the speed of
the "hover" effect:
Example
.button {
-webkit-transition-duration: 0.4s; /* Safari & Chrome */
transition-duration: 0.4s;
}
.button:hover {
background-color: #4CAF50; /* Green */
color: white;
}
In summary, for transitions where you want the "enter" and "exit" animations to be the same, you need to employ transitions on the main selector .button rather than the hover selector .button:hover. For transitions where you want the "enter" and "exit" animations to be different, you will need specify different main selector and hover selector transitions.
You have misunderstood :hover; it says the mouse is over an item, rather than the mouse has just entered the item.
You could add animation to the selector without :hover to achieve the effect you want.
Transitions is a better option: http://jsfiddle.net/Cvx96/
The opposite of :hover appears to be :link.
(edit: not technically an opposite because there are 4 selectors :link, :visited, :hover and :active. Five if you include :focus.)
For example when defining a rule .button:hover{ text-decoration:none } to remove the underline on a button, the underline shows up when you roll off the button in some browsers. I've fixed this with .button:hover, .button:link{ text-decoration:none }
This of course only works for elements that are actually links (have href attribute)
This will add background color to the .icon when hovered and background fades when mouse pointer left the element..
.icon {
transition: background-color 0.5s ease-in-out; /* this is important */
}
.icon:hover {
background-color: rgba(169, 169, 169, 0.9);
}
I have a list with one item on the list transitioning to the northeast when I hover over it. Using margin-top and margin-left property transitions worked but the item being hovered over kept pushing other elements so I added position:relative and tried using top and left transition properties but it didn't seem to be working.
Here is the jsfiddle:
list hover
Add left, top default
link demo
left: 0px
Have you tried setting the parent of your list. I know sometimes relative has issue unless the underlying item is also relative or absolute. Just a thought.
Use position:absolute and it will take it out of the normal document flow. You could also give it z-index:5 to make sure it floats over other elements.
.transition{
transition: all .4s;
-moz-transition: all .4s;
-webkit-transition:all .4s;
-o-transition: all .4s;
margin-top:20px;
border:1px solid gray;
width:80px;
padding:10px;
margin-left:50px;
position:relative;
cursor:pointer;
}
.hover_top{
top:0;
}
.hover_top:hover{
top:-10px;
}
.hover_left{
left:0;
}
.hover_left:hover{
left:-10px;
}
.hover_right{
right:0;
}
.hover_right:hover{
right:-10px;
}
<div class="hover_top transition"> Hover Top </div>
<div class="hover_left transition"> Hover Left </div>
<div class="hover_right transition"> Hover Right </div>
You have to define the property where you want to apply the transition effect. For example:
.box { position: relative; transition: all 0.4s ease;}
.box:hover { top: -1rem;}
that will not work. So you have to define top: 0 by default then top -1rem on hover. like
.box { position: relative; transition: all 0.4s ease; top:0}
.box:hover {top: -1rem}
that will work.
This is what I have:
.box{
background:#FFF;
-webkit-transition: background 0.5s;
}
.box:hover{
background:#000;
}
But this appends to both onmouseover and onmouseout actions, but isn't there a way to control them? Something like:
-wekbkit-transition-IN: background 1s;
-webkit-transition-OUT: background 10s;
Just redifine your transition in the over pseudo element.
.box{
background: white;
-webkit-transition: background 5s;
}
.box:hover{
background: olive;
-webkit-transition: background 1s;
}
Look my http://jsfiddle.net/DoubleYo/nY8U8/
Either use an animation (only in webkit currently), or use JS to add and remove the properties, they will still animate.
