this question might be obvious but i'm new in css.
I'm animating a shape so when you hover it, it stretches. I've completed the hover on with a nice ease transition but when you move off the mouse the transition doesn't work. Is there a way to make it happen also in the hover off moment?
.shape1{
position: absolute;
background:red
top:512px;
width:180px;
height:140px;
}
.shape1:hover {
height: 160px;
top:492px;
transition: 0.2s ease;
}
Your answer
You have added the transition property on the hover state of the element. Therefore the transition is not applied when you leave the cursor from the element.
.shape1{
position: absolute;
background: red;
top: 512px;
width: 180px;
height: 140px;
transition: .2s ease; /* move this here from :hover */
}
Further information
Besides this you can also add specific properties to the transition. For example, if you only want the height to be animated you could it like this:
.shape1 {
transition: height .2s ease;
/* this inly affects height, nothing else */
}
You can even define different transition-times for each property:
.shape1 {
transition: height .2s ease, background-color .5s linear;
/* stacking transitions is easy */
}
Add the transition before the :hover, so the transition always applies
.shape1 {
transition: 0.2s ease;
}
The :hover selector is used to select elements when you mouse over them.

When you add also transition to your shape1 class it should works

I want to apply for CSS transition different values on hover in ease-in and ease-out.
Like this,
ease-in: 180ms,
ease-out: 240ms
when I hover it will be 180ms ease-in, but when hovering out it will be 240ms ease-out.
You can use different transition-duration values for the styles affecting your element, for example:
div {
width: 150px;
height: 150px;
background-color: gray;
transition: width 180ms ease-in;
}
div:hover {
width: 300px;
transition-duration: 240ms;
transition-timing-function: ease-out;
}
<div>My Element</div>

I've created a menu that adjusts itself as it gets past a certain point of the screen. Everything works great, except for transitions and only on Chrome.
I tried adding a -webkit- version of the transition, but it doesn't work either.
This is my CSS
.past-main {
height: 97px !important;
margin-left: -40px;
width: 100%;
top: 0px !important;
position: absolute;
-webkit-transition: height 300ms opacity 300ms top 300ms ease 0s;
transition: height 300ms, opacity 300ms,top 300ms ease 0s;
opacity: 1!important;
height: 90px !important;
margin-top:0px !important;
}
.past-maina {
-webkit-transition: top 800ms ease 0s;
transition: top 800ms ease 0s!important;
top:0px!important;
}
.past-mainb {
-webkit-transition: all 800ms ease 0s;
transition: all 800ms ease 0s;
margin-top:0px!important;
}
To add more context, the various levels of your header menu gets those classes applied when the user scrolls past a certain point:
some wrapper elements get past-maina and past-main
each menu item (they are li elements) gets past-mainb
Before scrolling down, each menu item has varying margin-top values; afterwards they all get 0. These are set with style rules like
.desktop-nav ul li:nth-child(1) {
margin-top: -10px;
}
Now, this selector has a higher specificity (22) than your .past-mainb selector (10), which, I'm guessing, is why you added the !important annotation to the latter's rule: otherwise, it wouldn't take effect.
But this had an undesired side effect: important declarations always win over transitions! Thus, if you want your transitions to take effect you can't use !important.
The simple cheat is to up the specificity of the "past main" style rules. For example, add an ID selector. Or perhaps better: instead of adding a class when the user scrolls, remove a "before main" class instead, and rewrite all the rules giving specific menu-item margins to use it:
.desktop-nav.before-main ul li:nth-child(1) {
margin-top: -10px;
}
First stackoverflow post, so please forgive if I'm missing something obvious. I did search for an answer first but didn't find one I recognized as relevant.
In this jsfiddle, I have a div that I'm using as a hover target to get some transitions to happen to an <a> element.
http://jsfiddle.net/ramatsu/Q9rfg/
Here's the markup:
<div class="target">Target
<p>.LightMe</p>
</div>
And the css:
body {
background-color: #099;
height: 100%;
width: 100%;
margin-top:200px;
}
.target{
position: absolute;
left: 40%;
height: 100px;
width: 200px;
padding: 20px;
background-color: #ccc;
cursor: pointer;
}
a {
display: block;
position: relative;
padding: 1px;
border-radius: 15%;
}
a.LightMe {
/*Starting state */
background-color: white;
border-style:solid;
border-color:#fff;
top: -120px;
left: -200px;
height: 80px;
width: 80px;
z-index: 10;
opacity: 0;
transition:left 0.55s ease, opacity .5s .7s ease;
-webkit-transition:left 0.55s ease, opacity .5s .7s ease;
-o-transition:left 0.55s ease, opacity .5s .7s ease;
}
.target:hover a.LightMe {
/*Ending state*/
left: 80px;
opacity: 1;
transition:left 0.55s .7s ease, opacity .5s ease;
-webkit-transition:left 0.55s .7s ease, opacity .5s ease;
-o-transition:left 0.55s .7s ease, opacity .5s ease;
}
.target:hover {
transition: background-color 500ms ease;
-webkit-background-color 500ms ease;
-o-background-color 500ms ease;
background-color:#999;
}
Hover over the grey box labeled Target and back off again to see the transitions on the <a> element. It's doing what I want: opacity fades in during position delay, then it slides to the desired position. when moving out of the hover target, the <a> slides to it's original position, then opacity fades back out. All good so far.
The catch is, if the user hovers over the hidden <a> element, it triggers the same set of transitions, which causes all kinds of unintended havoc.
I'd like to prevent any response to a hover directly over the <a> element, and really like to continue to keep it in css if possible.
I tried adding an explicit hover to <a> and .LightMe to override this, to no avail. (Though that could be that I just didn't get the selector syntax right.)
I added the background-color transition to .target intentionally for testing, and it provided an interesting clue: hovering over the <a> triggers the upstream transitions of the .target div. That's about where my brain broke and I decided I'd better seek help.
I'm working with a few things here that are above my head, I just started from the closest thing I could find and worked toward what I needed. This was the starting point jsfiddle (with thanks to the author):
You can start your 'top' position outside of the viewer port and delay the 'top' transition until after your 'left' transition is over. That way the <a> element will not be clickable until the left transition start.
See: http://jsfiddle.net/Q9rfg/4/
Or you can also use this method, combined with the sibling selector as suggested by aorcsik.
Update: another hacky solution is to place a div which is outside, the hover sensitive element, that covers the moving link. Check it out: http://jsfiddle.net/aorcsik/Q9rfg/2/
The problem with my original idea (below) was, that you could not click on the moving link, since it returned to its original position, once you hovered out of the gray box, also the cursor changed over the hidden link.
I would try to get the <a> out of the gray box, put it after, and reference it in css with the sibling selector +.
.mainclass.subclass:hover + a.LightMe {
/* ... */
}
This way it won't trigger the hover effect of the gray box when itself is hovered, and you stay in pure css land.
This would make positioning a bit trickier, here is a fiddle, check it out: http://jsfiddle.net/aorcsik/Q9rfg/1/
For using mouse into one element we use the :hover CSS attribute. How about for mouse out of the element?
I added a transition effect on the element to change the color. The hover effect works fine, but what CSS attribute should I use for mouse out to apply the effect? I'm looking for a CSS solution, not a JavaScript or JQuery solution.
Here is the best solution, i think.
CSS onomouseout:
div:not( :hover ){ ... }
CSS onmouseover:
div:hover{ ... }
It's better, because if you need to set some styles ONLY onmouseout and trying to do this in this way
div { ... }
you will set your styles and for onmouseover too.
CSS itself does not support a mousein or mouseout selector.
The :hover selector will apply to the element while the mouse is over it, adding the style when the mouse enters and removing the style when the mouse leaves.
The nearest approach is to define the styles which you would place in mouseout within your default (non-hover) styles. When you mouse-over the element the styles within hover will take effect, emulating a mousein, and when you move your mouse off the element the default styles will take effect again, emulating mouseout.
Here is an example, taken from here:
div {
background: #2e9ec7;
color: #fff;
margin: 0 auto;
padding: 100px 0;
-webkit-transition: -webkit-border-radius 0.5s ease-in;
-moz-transition: -moz-border-radius 0.5s ease-in;
-o-transition: border-radius 0.5s ease-in;
-ms-transition: border-radius 0.5s ease-in;
transition: border-radius 0.5s ease-in;
text-align: center;
width: 200px;
}
div:hover {
background: #2fa832;
-webkit-border-radius: 100px;
-moz-border-radius: 100px;
border-radius: 100px;
-webkit-transition: all 1s ease;
-moz-transition: all 1s ease;
-o-transition: all 1s ease;
-ms-transition: all 1s ease;
transition: all 1s ease;
-webkit-transform: rotate(720deg);
-moz-transform: rotate(720deg);
-o-transform: rotate(720deg);
-ms-transform: rotate(720deg);
transform: rotate(720deg);
}
The transitions defined for the div:hover style will take effect when the mouse enters (and hover is applied). The transitions for the div style will take effect when the mouse leaves (and hover is removed). This results in the mousein and mouseout transitions being different.
I think that I've found the solution.
.class :hover {
/*add your animation of mouse enter*/
}
.class {
/*
no need for not(hover) or something else.
Just write your animation here and it will work when mouse out
*/
}
Just try it... :)
You only need the :hover , when you mouse out of the element, it'll return to it's default non-:hover state, like this:
.class { color: black; }
.class:hover { color: red; }
when you hover, the color will be red and when you "mouseout", the color will return to black because it no longer matches the :hover selector. This is the default behavior for all browsers, nothing special you need to do here.
I'm new to CSS and now facing a problem which I can't get rid of.
I made an animation using css3 keyframes. This animation simply changes the rotation of an image whenever someone hovers it. Now I wanted to link this image to a website, but the way I did it, the animation doesn't run at all.
<div class="tunein"><a href="http://www.google.com/">
<img src="https://www.google.com/images/srpr/logo3w.png"></a></div>
.tunein{
position: absolute;
top: 40%;
left: 10%;
display: block;
-webkit-transform:rotate(12deg);
-moz-transform:rotate(12deg);
}
.tunein a:hover{
animation: rotate 0.5s ease-out;
-moz-animation:rotate 0.5s ease-out;
-webkit-animation:rotate 0.5s ease-out;
}
js fiddle for you:
http://jsfiddle.net/9jMqc/
When i add the class tag into the a-element, the offset changes dramatically but the animation works.
I'd propose moving the events onto the <a> link, so moving them as per http://jsfiddle.net/9jMqc/2/
.tunein a {
display: block;
-webkit-transform:rotate(12deg);
-moz-transform:rotate(12deg);
}
.tunein a:hover{
animation: rotate 0.5s ease-out;
-moz-animation:rotate 0.5s ease-out;
-webkit-animation:rotate 0.5s ease-out;
}
I think you were perhaps missing display: block on the <a> link previously - Just for reference, you shouldn't need to use display: block on <div></div>'s as that's their default unless otherwise declared in your CSS.
