I have read a couple of tutorials online, but I can't seem to get a cross-browser working example together.
HTML:
<div ng-include="show ? 'views/registration/form_activation.html' : null" ng-animate class="drop-down"></div>
CSS:
/* ANIMATIONS */
.drop-down {
-webkit-transition: all linear 1s;
-moz-transition: all linear 1s;
-ms-transition: all linear 1s;
-o-transition: all linear 1s;
transition: all linear 1s;
line-height: 100%;
}
.drop-down.ng-enter,
.drop-down.ng-leave-active {
opacity: 0;
max-height: 0px;
}
.drop-down.ng-enter-active,
.drop-down.ng-leave {
opacity: 1;
max-height: 100%;
}
What I would like to accomplish is that when the template is loaded with ng-include, it fades in from 0 to 100 opacity, and that it simultaneously opens like a dropdown (starting from 0, to full height that it needs). And vice versa when the form gets hidden.
The opacity already works, but changing the height does not, the div instantly appears with full height. Can some help me build the CSS with a cross-browser solution?
you have to define max-height in px in .drop-down class to make it work.
you can put any high value to max-height in px as you are anyways not defining the height.
also define overflow: hidden in .drop-down so that content is hidden on transition of height.
worked for me.

I have a web page that contains five divs. A user can switch between the divs by clicking a next or previous button. If next is clicked, I fade-in the next div on top of the existing one and fade-out the existing div. Imagine something like flipping through some pictures.
My problem is, I am only animating the opacity property. Because of this, the users cannot interact with some of the elements of the visible div. My hunch is that its because there is an invisible div on top of it.
#keyframes fadeIn { from { opacity:0; } to { opacity:1; }}
#keyframes fadeOut { from { opacity:1; } to { opacity:0; }}
.fade-in {
opacity: 0;
position: relative;
top: 0;
left:1rem;
animation: fadeIn 0.3s ease-in;
animation-fill-mode: forwards;
}
.fade-out {
opacity: 1;
position: relative;
top:0px;
left:1rem;
animation: fadeOut 0.3s ease-in;
animation-fill-mode: forwards;
}
Is there a way using CSS, that I could change the display property from inline to none when the fade-out animation has completed? I know I could wire up some jQuery. However, that seems kind of clumsy. It seems like there should be a way for me to change an element from visible to hidden after the 0.3s have elapsed.
Any help is appreciated.
Yes, opacity will keep the invisible overlaying elements on-top.
Animate opacity, but at the same time toggle visibility from/to hidden/visible allowing interaction with underlying elements once an element is visibility:hidden
Also, instead of relative since you want a fade-trough effect, absolute should best fit your requirements.
I'm currently trying to implement some CSS transition effects on a set of different panels, to give the appearance that they are "sliding in" from off screen. I want them each to appear in a different direction (e.g. top to bottom, left to right, etc.)
Presumably, to do bottom to top and right to left, I would just want to set translateX or translateY, but with a positive value, rather than negative. And then for all of them, I would just translate the value to 0 when I want them to appear on screen.
Here is a really simplified version of what I am trying to do:
HTML:
<div class="container">
<div id="about" class="panel">
<h2>About</h2>
<p>I'm Mike and I don't know!</p>
Close
</div>
<div id="projects" class="panel">
<h2>Projects</h2>
<p>Here are some projects I have worked on.</p>
Close
</div>
<div id="contact" class="panel">
<h2>Contact</h2>
<p>You can find me all over the Internet!</p>
Close
</div>
<div id="blog" class="panel">
<h2>Blog</h2>
<p>Here are some blog posts.</p>
Close
</div>
projects
blog
about
contact
</div>
CSS:
.container {
overflow:hidden;
position:relative;
width:100vw;
height:100vh;
}
.panel{
min-width: 100%;
height: 100%;
position: absolute;
box-shadow: 0px 4px 7px rgba(0,0,0,0.6);
z-index: 2;
-webkit-transition: transform .8s ease-in-out;
-moz-transition: transform .8s ease-in-out;
-o-transition: transform .8s ease-in-out;
transition: transform .8s ease-in-out;
}
.panel:target {
-webkit-transition: transform .8s ease-in-out;
-moz-transition: transform .8s ease-in-out;
-o-transition: transform .8s ease-in-out;
transition: transform .8s ease-in-out;
}
.panel#contact {
transform: translateX(110%);
background-color:whitesmoke;
}
.panel#about {
transform: translateX(-110%);
background-color: red;
}
.panel#projects {
transform: translateY(110%);
background-color: blue;
}
.panel#blog {
transform: translateY(-110%);
background-color: gold;
}
.panel#contact:target{
transform: translateX(0%);
}
.panel#about:target{
transform: translateX(0%);
}
.panel#projects:target{
transform: translateY(0%);
}
.panel#blog:target{
transform: translateY(0%);
}
Note that the "About" and "Blog" links are transitioning as expected, whereas the "Projects" and "Contact" links appear to cause weirdness. Those are the two with positive values.
I'm having a really difficult time:
a.) understanding what the problem is exactly
b.) how can I fix it (if at all)
If someone could both explain what the browser is doing right now with those erroneous transitions and provide a solution, I would be much obliged. AFAIK, this is happening in every browser (that supports the :target pseudo element, anyway).
Let me know if you need clarification. Thanks a lot!
UPDATE: Not fixed, but I noticed that if you set the values to <98% for the offending element panels (Projects + Contact), the page transitions properly, though it isn't hidden from the screen. Not sure what that means, but if it helps...
UPDATE 2.0: Thanks for the comments, folks! I tried adding a container, and have updated the HTML and CSS to reflect that. The changes in question are a container div that wraps the panels, as well as the following CSS for that container:
.container {
overflow:hidden;
position:relative;
width:100vw;
height:100vh;
}
I'm still having similar behavior -- this is also updated in the Codepen. I think I understand now the issue, but I'm not quite sure why the page is still jumping to that element in question before applying the transformation. I can imagine there is some hacky way to get around this, but I would rather do it the "right" way.
I decided that using :target and trying to have this be pure CSS wasn't really the way to go, and wound up just using Javascript in a fairly straightforward manner.
Lesson learned: Don't try to do things w/ Pure CSS unless you really have to.
I have to make a responsive website and as i shrink the browser to a specified size, i want the logo on the left to move to the right so that it is in the centre.
Here's an example of the transition i want to achieve. It is under "2.Animating your transitions" box1
I know that the transition starts on hover but is it possible to activate it when the browser is resized? or any alternative methods at all?
You can do this by using a mixture of CSS3 transitions and the #media queries.
div
{
height: 100px;
width: 200px;
position: relative;
background-color: #eee;
-webkit-transition: all 1s ease-in-out;
-moz-transition: all 1s ease-in-out;
-o-transition: all 1s ease-in-out;
-ms-transition: all 1s ease-in-out;
transition: all 1s ease-in-out;
}
#media all and (min-width: 400px) {
div
{
background-color: #fc3;
left: 100px;
}
}
What this does is sets up the transitions on the element with relative position but obviously does not fire them (as there's no :hover or other selector) and declares a change in position (left: 100px;) when the browser is more than 400px wide. Use max-width for a "more than" value.
Obviously you need to change the values to what you need, but this is how it should be done.
http://jsfiddle.net/AvhvD/
Here is how i would do:
1: .logo { display block, width: xxx; margin 0 auto; transition: margin ... }
2: #media (...) {
.logo {
margin-left: 0;
}
}
I was thinking that you could make a conditional statement in JavaScript and Jquery that would test the following to be true: If the browser window is resized and the size of the browser window is between a range, add a css class. If not remove the css class.
With this new class created, maybe you can make an animation using CSS3. I am not too familiar if this would work, but you could always just revert back to JQuery.
Furthermore, I don't know if transitions can be applied inside of media queries. If so, I am a big proponent and would highly recommend using them.
Hope I could help.
I'm trying to do a sort of accordion for my website, similar to the one on this website, but without the toggling.
The code I'm working with is here.
I have the basic setup working, but I can't seem to get the height of the li to transition properly (if at all); I'd appreciate some help.
Preferably the solution would only use CSS, but I am willing to use JS/jQuery if that's the only/best way.
I have tried reading other questions on this site to fix it, but I'm either doing something wrong or the solutions didn't help.
One way is to use CSS3 transitions (works in modern browsers), but it won't be possible (someone may correct me if I'm wrong) to transition height: 0; to height: 100%; So if you don't know the actual height, one way around it is to use max-height instead. In this case you will need to set the max-height to something greater than it will ever get.
So adding something like this might be what you are looking for?
li {
opacity: 0;
max-height: 0;
}
h2:target~li { /* Want to transition this */
opacity: 1;
max-height: 100px;
-webkit-transition: max-height 1.0s;
-moz-transition: max-height 1.0s;
-ms-transition: max-height 1.0s;
-o-transition: max-height 1.0s;
transition: max-height 1.0s;
}
DEMO
In your case, if you want to transition the opacity property as well you can just change transition: max-height 1.0s; to transition: all 1.0s; which means that you will transition all properties.
Here's a link if you want to read about CSS3 transitions:

i am wondering if it is possible to set the height of a div with css animation.
I have a div that when you hover over it opens up but i want it to stay that height not shrink back to the original height.
Is this possible?
it needs to be done in pure css not javascript as its a website for college
You can do something like this:-
HTML:
<div class="divAnimate" onmouseout="this.className='setHeight'">Div Height Animation</div>
CSS:
.divAnimate {
border: 1px solid;
}
.divAnimate:hover {
height: 200px;
}
.setHeight {
height: 200px;
border: 1px solid;
}
Refer LIVE DEMO
You should use jQuery. CSS3 is not supported in all browsers. However, it is possible to use CSS3 to achieve this.
CSS:
#myDiv {
height:20px;/* initial height */
width:100px;
background:#aaa;
-webkit-transition: height .4s linear; /* you can replace 'height' with the attribute you are changing (eg: color, width...)*/
-moz-transition: height .4s linear;
-o-transition: height .4s linear;
-ms-transition: height .4s linear;
transition: height .4s linear;
}
#myDiv:hover {
height:100px; /* desired height */
}
HTML:
<div id="myDiv">
Hello World!
</div>
Hope this helps.
EDIT: Sorry, I didn't see that you needed it to stay that height. In order to do that, you would need to use something like onmouseout (or another event listener), which in the end would use Javascript anyway.
Yes, this is possible with just CSS3, but will only work in Safari/Chrome and recent versions of Opera, Mozilla Firefox, and IE10 as you need CSS3 animation keyframes to preserve the end-state of the transition.
