I want this div-container hidding (display:none) for 2 sec.
or if you have a better solution, please post it :)but please no jquery or javascript
#vcontainer {
height: 450px;
width: 100%;
background-color:black;
margin-top:10px;
margin-bottom:10px;
animation: vldng 4s;
-webkit-animation: vldng 4s;
display: none;
}
#keyframes vldng {
0%{display: none;}
50%{display: block;}
100%{display: block;}
}
#-webkit-keyframes vldng {
0%{display: none;}
50%{display: block;}
100%{display:block;}
}
I hope you can help me! :)
you can use Opacity instead of display.
but opacity=0 is different from display=none,
in both state you don't see anything.
opacity:0 make your element acting as a Place Holder, but display:none remove your element from view port.

I'm maybe 2 weeks into coding so apologies if I don't format correctly (code and question itself).I am trying to set a delay for the time it takes the buttons to switch text. Thank you for the help!
I've tried googling this and youtube with no luck.
I have tried adding
transition
transition-delay
body{
background-color: black;
}
.column{
position: fixed;
left:0;
bottom:0;
top:55px;
width:72px;
z-index: 200;
padding-top: 20px;
}
.about,
.skills {
font-size:72px;
width: 10em;
text-align: left;
border:none;
background-color: black;
color:red;
}
.about:hover span {
display: none;
}
.about:hover:after {
transition-delay: 3s;
content: "ABOUT";
}
.skills:hover span {
display: none
}
.skills:hover:after {
content: "SKILLS"
}
<h1>
<div class="column">
<button class="about" data-hover="ABOUT">
<span>
I
</span>
</button>
<button class="skills">
<span>
AM
</span>
</button>
</div>
</h1>
First of all, I would look into the html semantics a bit. Having div tags inside an h1 doesn't make much sense. So consider changing the h1 to a div. Also, the 3s delay is enormous. Think of something a bit faster, like 300ms.
The real issue is that display states and transition don't really work together since it swaps between states like block and none. But there are other solutions to this. You could use position: relative; on a parent div and give the children position: absolute. This way, you could make the transitions with opacity instead.
I have made an example for you so you can get the idea. I have commented on the CSS so you can follow up on what is happening.
/* Lets give our spans some styling: */
span{
font-size: 30px;
font-weight: 600;
font-family: sans-serif;
margin-bottom: 2rem;
max-width: 60ch;
}
/* Lets make the "container" position relative,
this way the absolute children will stay inside the container */
.hover-effect{
position: relative;
}
/* Let's give both of the children position absolute */
.hover-effect span{
position: absolute;
color: black;
opacity: 100%;
transition: 300ms ease-in 300ms; /* Delay: 300ms*/
}
/* Let’s override the previous.
This actually happens when we remove the hover, so we want to
trigger this animation first, hence the delay of 0ms*/
.hover-effect span.on-hover{
opacity: 0%;
transition: 300ms ease-in 0ms;
}
/* When we hover the container, let's change both spans */
.hover-effect:hover span{
color: red;
opacity: 0%;
transition-delay: 0ms;
}
/* Let’s override the previous.
When we hover on the container, the span with the class "on-hover"
becomes visible, and we wait 300ms before it happens so that the
"disappearing" animation gets its time to trigger. */
.hover-effect:hover span.on-hover{
opacity: 100%;
transition-delay: 300ms;
}
<div class="hover-effect">
<span>Try and hover over me</span>
<span class="on-hover">Try and remove the hover</span>
</div>
I know in css, the unordered list bullet image can be change by following code:
ul { list-style-image: url(image)}
can I use an animation like
width: 25px;
height: 25px;
background: red;
animation: mymove 5s infinite;
}
#keyframes mymove {
from {background-color: red;}
to {background-color: blue;}
}
as the bullet image? if not, then how to use animated image as bullet image?
To change the color of the bullet you need to modify the color property of the list but this will make your text color change too, so you need to wrap your text inside other element, like a <span> and modify its color too.
Then you can create a keyframe animation with the color property changing and apply it to the list as you did.
ul li {
color: red;
animation: animate 4s linear infinite;
}
ul li span {
color: black;
}
#keyframes animate {
0% {
color: red;
}
50% {
color: blue;
}
100% {
color: red;
}
}
<ul>
<li><span>Item</span></li>
<li><span>Item</span></li>
<li><span>Item</span></li>
</ul>
This is becoming easier with new features in Chrome and Firefox so keep updated!
Btw it is not related to javascript
I am trying to animate with CSS the a line through on a bit of text, but it's not actually animating, just going from hidden to displayed. Can anyone advise if what I'm trying is actually possible? If not, is there another way to achieve this?
HTML:
<div>
The text in the span <span class="strike">is what I want to strike out</span>.
</div>
CSS:
#keyframes strike{
from{text-decoration: none;}
to{text-decoration: line-through;}
}
.strike{
-webkit-animation-name: strike; /* Chrome, Safari, Opera */
-webkit-animation-duration: 4s; /* Chrome, Safari, Opera */
animation-name: strike;
animation-duration: 4s;
animation-timing-function: linear;
animation-iteration-count: 1;
animation-fill-mode: forwards;
}
You can use a pseudo like this
Note (thanks to Phlame), this left-to-right animation won't work if the line to strike breaks in to a second line. For that one need to use yet another pseudo element and some script to position the two properly. Or use some other animation effect, e.g. like the one suggested in Oriol's answer.
#keyframes strike{
0% { width : 0; }
100% { width: 100%; }
}
.strike {
position: relative;
}
.strike::after {
content: ' ';
position: absolute;
top: 50%;
left: 0;
width: 100%;
height: 1px;
background: black;
animation-name: strike;
animation-duration: 4s;
animation-timing-function: linear;
animation-iteration-count: 1;
animation-fill-mode: forwards;
}
<div>
The text in the span <span class="strike">is what I want to strike out</span>.
</div>
It depends on how you want to animate it.
Since text-decoration-color is animatable, you can animate it from transparent to auto.
But this property is not widely supported yet.
#keyframes strike {
from { text-decoration-color: transparent; }
to { text-decoration-color: auto; }
}
.strike {
text-decoration: line-through;
animation: strike 4s linear;
}
<div>
The text in the span <span class="strike">is what I want to strike out</span>.
</div>
Here's a variation on the accepted answer, using an image to provide an animated "scribble" strike-through.
html {
font-family: Helvetica;
font-size: 24px;
}
.strike { position:relative; }
.strike::after {
content:' ';
position:absolute;
top:50%; left:-3%;
width:0; height:10px;
opacity:80%;
transform:translateY(-50%);
background:repeat-x url(data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAB0AAAAKAQMAAAByjsdvAAAABlBMVEUAAADdMzNrjRuKAAAAAXRSTlMAQObYZgAAADdJREFUCNdj+MMABP8ZGCQY/h9g+MHw/AHzDwbGD+w/GBhq6h8wMNj/b2BgkP8HVMMPUsn+gQEAsTkQNRVnI4cAAAAASUVORK5CYII=);
animation: strike 2s linear .3s 1 forwards;
}
#keyframes strike { to { width: 106%; } }
This thing and <span class="strike">this thing and</span> this thing.
It's very elegant, IMO, to use linear-gradient as background, and paint line which is the same color as the text (currentColor).
This solution is very flexible, opens up the door to many interesting effects and is also much less code than a pseudo-element solution.
PS: It also supports multi-line texts
From my CodePen:
span {
--thickness: .1em;
--strike: 0;
background: linear-gradient(90deg, transparent, currentColor 0) no-repeat
right center / calc(var(--strike) * 100%) var(--thickness);
transition: background-size .4s ease;
font: 25px Arial;
padding: 0 .2em;
}
span:hover {
--strike: 1; /* "1" means "true" (show the strike line) */
background-position-x: left;
}
<span contenteditable spellcheck='false'>
Strike-through animation (hover)
</span>
According to W3Schools, the text-decoration property is not animatable.
However, if you use jQuery, you can. (See here)
I'm building a small website and would like to get the text (and an image when I add one) to fade in when someone accesses the website?
Thanks!

http://codepen.io/JTBennett/pen/GorVRL [your site w/ fade and motion]
http://codepen.io/JTBennett/pen/BjpXRo [example of the following instructions]
Here's an example. The HTML requires a div to be wrapped around the whole of the body content if you want it to fade in all at once. Look for this:
<div class="wrapper fade-in">
There's a lot of stuff you can do with CSS, I've been using it for years and I still learn something new every once in a while.
All the animation commands will appear in your CSS like so:
#keyframes fadeIn
to {
opacity: 1; }
Then your divs are going to have a class that calls the animation (#keyframes):
.fade-in {
animation: fadeIn 1.0s ease forwards;
[other div properties can be included here]
}
The HTML will look like this:
<div class="fade-in">
[content]
</div>
Finally, you'll need to make sure you include the vendor codes to make it compatible with all browsers [which adds a fair amount of code, which is why jQuery can be a better option for this stuff]:
#keyframes fadeIn{
0% {
opacity:0;
}
100% {
opacity:1;
}
}
#-moz-keyframes fadeIn {
0% {
opacity:0;
}
100% {
opacity:1;
}
}
#-webkit-keyframes fadeIn {
0% {
opacity:0;
}
100% {
opacity:1;
}
}
#-o-keyframes fadeIn {
0% {
opacity:0;
}
100% {
opacity:1;
}
}
#-ms-keyframes fadeIn {
0% {
opacity:0;
}
100% {
opacity:1;
}
}
The vendor codes will have to be duplicated again in your div class in the CSS:
.fade-in {
animation: fadeIn ease 5s;
-webkit-animation: fadeIn ease 5s;
-moz-animation: fadeIn ease 5s;
-o-animation: fadeIn ease 5s;
-ms-animation: fadeIn ease 5s;
}
The effect can be achieved with jQuery much quicker, as you can see in one of the other answers here.
After you've learned to do it by hand, I suggest playing around with this CSS3 animation generator if you want to save a bit of time:
http://cssanimate.com/
Just make sure you understand it first though.
Lastly, this is an example of jQuery performing similar functions (though using SVGs instead of divs this time, same process though):
http://codepen.io/JTBennett/pen/YwpBaQ
I don't know what element you have but you can do a few things.
If you are using javascript, or jquery you can make an element fade in easily.
Jquery:
$(document).ready(function(){
$('.myItemClass').fadeIn();
});
You can also do it with just CSS
CSS:
/* The animation code */
#keyframes example {
from {opacity: 0;}
to {opacity: 1;}
}
.myClass {
animation-name: example;
animation-duration: 1s;
}
You can fade in elements when the document loads by loading the page with the elements hidden (opacity : 0;) in CSS. Then on document ready you can remove the class, so long as it has a transition for that css property—you'll have an effect.
CSS
div {
transition: opacity 2s;
opacity: 1;
}
.hidden {
opacity: 0;
}
JS
$(document).ready(function(){
$('.hidden').removeClass('hidden');
});
It is very simple don't need even jqyery, pure CSS and pure Javascript.
CSS
body {
opacity:0;
transition: 300ms opacity;
}
Javascript
function pageLoaded() {
document.querySelector("body").style.opacity = 1;
}
window.onload = pageLoaded;
I'm trying make an animation as if I was typing. To achieve this I'm using CSS animation 'steps'.
The animation itself works just fine. However, if I want to animate multiple lines of text, they all start playing at the same time. Which isn't giving me the desired effect. (Tried using <br> in a single <h1>, which cut off the text, but again started the animations simultaneously.)
To counter this, I put the next line of text in an <h2> and set an animation-delay for every line of text. Which works, but the text is visible before the animation starts.
I want the text to be hidden until the animation starts playing, to really get that 'live typing' effect.
Anyone got any ideas on how I can achieve this?
HTML
<div class="content">
<h1>Hi there! My name is Jeff.</h1>
<h2>And I create cool stuff.</h2>
</div>
CSS
.content h1 {
background:white;
opacity:0.7;
white-space:nowrap;
overflow:hidden;
border-right: 3px solid black;
-webkit-animation: typing 2s steps(26, end),
blink-caret 1s step-end 2s;
}
.content h2 {
background:white;
opacity:0.7;
white-space:nowrap;
overflow:hidden;
border-right: 3px solid black;
-webkit-animation: typing 2s steps(26, end),
blink-caret 1s step-end infinite;
-webkit-animation-delay:3s;
}
#-webkit-keyframes typing {
from { width: 0; }
to { width:400px; }
}
#-webkit-keyframes blink-caret {
from, to { border-color: transparent }
50% { border-color: black }
}
jsFiddle
The simplest solution is to add:
animation-fill-mode:both;
to your h2 (with the necessary prefixes). That way, you aren't setting it to a zero width outside of your animation, so browsers that don't support this CSS will display the heading (which I guess is what you're after). See this fiddle.
The animation-fill-mode:
specifies how a CSS animation should apply styles to its target before
and after it is executing
Setting it to both in this instance means that your h2 will have a width of 0 before it starts executing, and a width of 400px after.
As the comments already include a solution, perhaps this might be another way of doing it - by using timeouts and setting visibility: hidden at the beginning (For simplification I just used jQuery to set the visiblitiy).
Include the following CSS rule:
.content {
visibility: hidden;
}
As JavaScript you would have:
window.setTimeout(function() {
$('#contentdiv h1').css('visibility', 'visible');
}, 100);
window.setTimeout(function() {
$('#contentdiv h2').css('visibility', 'visible');
}, 3100);
See the jsFiddle
p
{
font:500 22px consolas;
width:20ch;
white-space:nowrap;
overflow:hidden;
animation:type 5s steps(20) infinite;
}
#keyframes type
{
0%{ width:0; }
}
<p>Text Type Animation</p>
Not quite the OP's question, but in case someone else finds this useful:
I wanted to be able to typing-animate a pararaph of text, a single <p> tag which might contain text that would wrap, and produce an unknown number of actual lines. Applying a simple linear animation to the p tag itself wouldn't work, so instead, I took the approach of having several "hider" elements that would cover the paragraph of text, each one line high, and then I would animate each of those so they would shrink away, reveal characters from the line of text beneath them.
The HTML looks like this:
<div class="container">
<!-- container div is required to set absolute positions within it, so that .typing and .hiders exactly overlap -->
<p class="typing">
This paragraph of text will be animated
with a "typewriter" style effect, and it
will continue to work even if it splits across
multiple lines. Well, in this case, up to a
maximum of 5 lines, but you get the picture.
</p>
<div class="hiders">
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
</div>
</div>
You need a container, and position the .typing element and the .hiders using absolute so that they're on top of each other:
.container {
position: relative;
font-family: Consolas, monospace;
}
.typing {
position: absolute;
top: 0;
margin: 0;
z-index: -1;
}
.hiders {
margin: 0;
position: absolute;
top: 0;
width: 100%;
}
And the animation gets applied to each p inside the .hiders:
.hiders p {
position: relative;
clear: both;
margin: 0;
float: right; /* makes animation go left-to-right */
width:0; /* graceful degradation: if animation doesn't work, these are invisible by default */
background: white; /* same as page background */
animation: typing 2s steps(30, end);
animation-fill-mode: both; /* load first keyframe on page load, leave on last frame at end */
}
.hiders p:nth-child(2) {
animation-delay: 2s;
}
.hiders p:nth-child(3) {
animation-delay: 4s;
/* etc */
Here's the final fiddle:
