I want to hide and show a div using css like :
Show => Hide => Show =>...
for do that I've tried that code:
#showMe {
animation: cssAnimation 0s 2s forwards;
visibility: hidden;
}
#keyframes cssAnimation {
to { visibility: visible;
}
}
but it will hide it only plz guys help!!
One way to do this is by adding keyframes for a specific progress (time-progress).
Some attributes in CSS are not animateable, so if you try to animate them they get instantly set to your "to" value, which is visible. To work around this, we simply set the visibility to hidden(in css) and keep it until 50% (in animation). At 51% we set it to visible, where it gets instantly shown (until the end).
To make it "blinking" you can repeat this animation by appending infinite which is a shorthand for animation-iteration-count: infinite.
#showMe {
animation: cssAnimation 1s infinite;
visibility: hidden;
}
#keyframes cssAnimation {
50% {
visibility: hidden;
}
51% {
visibility: visible;
}
}
<div id="showMe">(╯°□°)╯︵ ┻━┻</div>
Try to add property animation-iteration-count and set value it to infinite. It should play the animation infinite times.

I want elements to appear one by one on the page with an animation. I created the animation but I don’t know how to hide (not display: none) the element while delay function is in use.
So, after 1 second, element appears with appear animation, however there must be something else to hide it before animation starts.
.insta {
animation: appear 0.4s linear 1s;
}
#keyframes appear {
0% {
opacity: 0;
transform: translateX(30%);
}
100% {
opacity: 1;
transform: translateX(0%);
}
}
<p class=«insta»>Instagram</p>
Set opacity: 0. That hides your text. Using animation-fill-mode: forwards will let you have the properties added at the end of the animation.
You can solve it by adding an animation-fill-mode: both; to your CSS. That means that the browser will apply the animation's first frame until it starts, and its last frame after it has finished.
Since your animation starts with opacity: 0; and ends with opacity: 1;, no further modifications required.
You can also combine it into the animation property (just add a both keyword somewhere):
.insta {
animation: appear 0.4s linear 1s both;
}
#keyframes appear {
0% {
opacity: 0;
transform: translateX(30%);
}
100% {
opacity: 1;
transform: translateX(0%);
}
}
<p class="insta">Instagram</p>

I'm trying to use CSS animations to make a hyperlink blink until it has been visited. However, my current code doesn't work – it continues blinking even after it is clicked.
How can I cause the link to stop blinking after it has been visited?
My CSS:
blink {
-webkit-animation: 0.5s linear infinite condemned_blink_effect;
animation: 1.5s linear infinite condemned_blink_effect;
}
#-webkit-keyframes condemned_blink_effect {
0% {
visibility: hidden;
}
50% {
visibility: hidden;
}
100% {
visibility: visible;
}
}
#keyframes condemned_blink_effect {
0% {
visibility: hidden;
}
50% {
visibility: hidden;
}
100% {
visibility: visible;
}
}
blink:visited{
-webkit-animation: none;
animation: none;
}
My PHP code that generates the link HTML is:
echo "<td width='150'><a href='dispdata.php?id=" . $dataReturn->dataID . "'><blink>View </a><blink></td> ";
The <blink> element was never part of the HTML standard and was a joke added in a version of Netscape at some point. Modern browsers don't support this element at all because everyone agrees blinking elements are annoying. See more details here.
You can still produce a blinking effect through CSS like you tried, but your selectors are incorrect. :visited can only apply to links (<a> elements) but you wrote blink:visited. That won't work, as this means "select all <blink> elements that are also visited <a> elements". An element can't be both, so the selector never works.
Finally, the styles that can be set on a :visited selector are limited because of the potential security risks. One could abuse this selector to steal a user's browsing history. See more details here. If you want to make a specific link open a page in a new tab and then stop blinking, you will need JavaScript.
For example, you could use a blinking CSS class to make the link blink and then remove the class from the element when it is clicked. In this code, I put the blinking effect on a nested <span> element because otherwise you wouldn't be able to click the link while it is hidden by the animation.
Again, this is not something I would recommend using at all as it will annoy your users.
function stopBlinking(e) {
e.currentTarget.classList.remove("blinking");
}
const blinking = document.querySelectorAll(".blinking");
for (link of blinking) {
link.addEventListener("click", stopBlinking);
}
.blinking span {
-webkit-animation: 0.5s linear infinite condemned_blink_effect;
animation: 1.5s linear infinite condemned_blink_effect;
}
#-webkit-keyframes condemned_blink_effect {
0% {
visibility: hidden;
}
50% {
visibility: hidden;
}
100% {
visibility: visible;
}
}
#keyframes condemned_blink_effect {
0% {
visibility: hidden;
}
50% {
visibility: hidden;
}
100% {
visibility: visible;
}
}
<span>Sample link</span><br>

I want to do this effect (jsFiddle, when hover on button):
This is a part of the code i need i guess, what i want is:
every two seconds on a div with this button as the background-image:
i want the shining effect like in the fiddle, that will swoop in and out fast, after two seconds, another swoop, etc...
is it possible with css only?
if no, with javascript, what should be the case for me to do it?
Should i do an interval of:
setInterval(function(){
document.getElementById('btnDiv').classList.add('shining');
setTimeout(function(){
document.getElementById('btnDiv').classList.remove('shining');
,1000)
,2000)
I know it's a bit overkill for this kind of effects, isn't it?
Since you already have the effect you want on :hover, just convert it to an animation.
#element {
animation: pulse 1s linear infinite alternate;
}
#keyframes pulse {
from {
/* define initial state of animation here */
}
to {
/* define final state of animation here */
}
}
Using linear infinite alternate will make the pulse go back and forth between the two states. Depending on the effect you want to achieve, you may have better results by using something like 40% and 60% instead of from and to respectively, to add a bit of delay around the pulse.
#nodelay, #delay {
width: 100px;
height: 100px;
background-color: #080;
border-radius: 50px;
}
#nodelay {
animation: pulse 2s linear infinite alternate;
}
#delay {
animation: pulse-delay 2s linear infinite alternate;
}
#keyframes pulse {
from {background-color: #080}
to {background-color: #0f0}
}
#keyframes pulse-delay {
from, 40% {background-color: #080}
60%, to {background-color: #0f0}
}
<div id="nodelay"></div>
<div id="delay"></div>
This is my code:

I'm trying to fade the large background image in. I tried this:
#cover {
background: url(http://bootstrapguru.com/preview/cascade/images/carousel/imageOne.jpg) no-repeat center center fixed;
background-size: cover;
height:100%;
width: 100%;
position:fixed;
opacity:0;
transition: opacity 2s;
}
however the image never appears. What am I doing wrong?

You actually need an animation of the opacity, in which you set animation-fill-mode: forwards so the last frame continues to apply after the final iteration of the animation.
Updated fiddle: http://jsfiddle.net/NVk2N/7/
#cover {
...
-webkit-animation: 2s show;
-moz-animation: 2s show;
-ms-animation: 2s show;
animation: 2s show;
-webkit-animation-fill-mode: forwards;
-moz-animation-fill-mode: forwards;
-ms-animation-fill-mode: forwards;
animation-fill-mode: forwards;
}
#-webkit-keyframes show {
from { opacity: 0 }
to { opacity: 1 }
}
#-moz-keyframes show {
from { opacity: 0 }
to { opacity: 1 }
}
#-ms-keyframes show {
from { opacity: 0 }
to { opacity: 1 }
}
#keyframes show {
from { opacity: 0 }
to { opacity: 1 }
}
(of course you need to use vendor prefixes where necessary)
Note: If you need to fade-in only the background image (and not the whole element) you could load the background inside an absolute positioned pseudoelement (e.g. #cover:before) with a negative z-index and just apply the animation to the psuedoelement itself:
Here's an example on codepen: http://codepen.io/anon/pen/EJayr/
Relevant CSS
#cover {
position: relative;
width : ...;
height : ...;
}
#cover:before {
content : "";
position: absolute;
z-index : -1;
top : 0;
left : 0;
width : 100%;
height : 100%;
background: url(...) top left no-repeat;
-webkit-animation: 5s show;
-moz-animation: 5s show;
-ms-animation: 5s show;
animation: 5s show;
-webkit-animation-fill-mode: forwards;
-moz-animation-fill-mode: forwards;
-ms-animation-fill-mode: forwards;
animation-fill-mode: forwards;
}
Animations on pseudoelements work fine on every modern browser (except in Chrome < 26 — as reported on issue #54699 — but not really a problem, since the current version at this moment is 34.0.1847.116)
you need to use some js code to trigger the animation property. just add a new class for #cover with opacity:1 and on body load assign this class to cover.
example
<body onload="document.getElementById('cover').classList.add('showed');">
To trigger a transition you actually need a trigger.
You are setting a opacity of "0" and this is what you get: 0 opacity.
The transition would work if the declaration of opacity would change from 0 to 1.
That is what transitions do.
The solution of Fabrizio Calderan with the Animation should do the job.
Working with the other answers that have been given will give you a fade on all the elements within that element so this will no achieve your desired result.
The best way to do this is to:
1) Create a div with a z-index of 1 which holds your background image and what you want to fade
2) Create another div with a z-index of 10 which holds your content which you dont want to fade and position it over the background div with position absolute.
3) Animate the background image with jquery animate
I hope this helps and that will give you your desired outcome!
I believe you may use keyframes and animations to get the job done.
It's not possible with purely css to fade only the background image. Reference: How to fade in background image by CSS3 Animation
The answer there explains that you may use <img> inside a <div> that you apply the fade animation on as there is no other way without anything but css.
I'm trying to highlight a div that wraps a contact form so the user knows where to go to contact. my link will be something like this
Contact Us
Going with a class since this will be used on the site in two places.
right now the current background for #form is #f5f5f5 so what I want to do is Flash a random color like #ff0000 and slowly fade it out back to #f5f5f5
demo on dabblet.com
Target pseudo-class applied to element which you are scrolled to.
Add this to your css:
CSS:
#form {
background-color: #f5f5f5;
}
#form {
background-color: #f5f5f5;
}
#form:target {
animation: target-fade 1s 1;
}
#keyframes target-fade {
0% { background-color: #ff0000; }
100% { background-color: #f5f5f5; }
}
HTML markup:
link to target #form
<form id="form">
…
</form>
PS:
Accordingly to caniuse.com CSS properties: animation and keyframes is needed vendor prefixes such this:
.box_animation:hover {
-webkit-animation: myanim 1s infinite; /* value is demo only */
-moz-animation: myanim 1s infinite;
-o-animation: myanim 1s infinite;
animation: myanim 1s infinite;
}
#-webkit-keyframes myanim {…}
#-moz-keyframes myanim {…}
#-o-keyframes myanim {…}
#keyframes myanim {…}
PPS: dabblet using prefix free JS library to paste all necessary prefixes. Later without this library you can see all you need prefix syntax on css3please
You can use the Ariel Flesler's ScrollTo jQuery Plugin to scroll with animation.
And for changing color with animation you use the jQuery Color Animation Plugin
example
$('selector').scrollTo( '520px', 800 )
.animate({backgroundColor:'#ff0000'}, {duration:5000,queue:false});
Edits
If you want to fade it back you can use toggle function.
$('selector').scrollTo( '520px', 800 )
.toggle(function() {
$(this).animate({
{backgroundColor:'#ff0000'}, {duration:5000,queue:false});
},
function() {
$(this).animate({
{backgroundColor:'#f5f5f5'}, {duration:5000,queue:false});
});
