If I wanted to Change the width of an element twice and animate that. For example:
box{
height:100px;
width:100px;
}
.box:hover{
width:300px;
width:200px;
}
I think you need keyframes animation. It should works properly in your case.
like this
#keyframes box-size {
0%, 100% {
width: 100px;
}
50% {
width: 300px;
}
}
.box{
height:100px;
width:100px;
background: pink;
}
.box:hover{
animation: box-size 2s;
}
<div class="box"></div>

I have an image of a butterfly, something like this.
I am trying to figure out if there is any way to make it look like its wings are opening and closing with a 3D CSS transform/translate or animation, but without having to split the image up into parts (it can be a background image of a div though if that helps).
Yes, using background applied to two elements where each one will show only one half and then you simply rotate both on the Y axis.
.box {
width:300px;
margin:20px;
display:flex;
perspective:500px;
}
.box::before,
.box::after{
content:"";
padding-top:56%; /* ratio based on your image */
flex:1; /* half the main element size */
background-image:url(https://i.imgur.com/DgMoHC5.jpg);
background-size:200% 100%; /* twice bigger than the pseudo element to get half the image*/
animation:left 1s linear infinite alternate;
transform-origin:right;
}
.box::after {
background-position:right; /* get the right part of the image */
animation-name:right;
transform-origin:left;
}
#keyframes left{
to {transform:rotateY(60deg)}
}
#keyframes right{
to {transform:rotateY(-60deg)}
}
<div class="box"></div>
A more realistic animation with some translation:
.box {
width: 300px;
margin: 20px;
display: flex;
perspective: 500px;
}
.box::before,
.box::after {
content: "";
padding-top: 56%;
flex: 1;
background-image: url(https://i.imgur.com/DgMoHC5.jpg);
background-size: 200% 100%;
animation: left 0.5s linear infinite alternate;
transform-origin: right;
}
.box::after {
background-position: right;
animation-name: right;
transform-origin: left;
}
#keyframes left {
from {
transform: translateZ(80px) rotateY(-30deg)
}
to {
transform:translateZ(0px) rotateY(50deg)
}
}
#keyframes right {
from {
transform: translateZ(80px) rotateY(30deg)
}
to {
transform:translateZ(0px) rotateY(-50deg)
}
}
<div class="box"></div>
If you use animation effect before mix-blend-mode property you will not get mix blend mode.
Once you remove the animation class or disable animation, then mix-blend-mode will work.
What is the problem? I spent hours to solve just this simple thing. Please, help
.box {
background-color:yellow;
overflow:hidden;
border-radius:10px;
}
.box img{ mix-blend-mode:multiply}
.animate{
border:1px solid red;
width:30px; height:30px;
animation: spin 2s infinite linear;
}
#keyframes spin {
0% { transform: rotate(0deg); }
100% { transform: rotate(1turn); }
}
<div class="animate">123</div>
<div class="box">
<img src="https://placeimg.com/400/200/animals" alt="">
</div>
mix blend should take effect anyway
In the old times, adding a transform translateZ(0px) used to solve a lot of problems.
At least in my Chrome, seems to still be the case:
.box {
background-color:yellow;
overflow:hidden;
border-radius:10px;
transform: translateZ(0px); /* added */
}
.box img{ mix-blend-mode:multiply}
.animate{
border:1px solid red;
width:30px; height:30px;
animation: spin 2s infinite linear;
}
#keyframes spin {
0% { transform: rotate(0deg); }
100% { transform: rotate(1turn); }
}
<div class="animate">123</div>
<div class="box">
<img src="https://placeimg.com/400/200/animals" alt="">
</div>
Adding mix-blend-mode to the parent element also, solves the issue.
.box {
background-color:yellow;
overflow:hidden;
border-radius:10px;
mix-blend-mode:multiply;
}
.box img{ mix-blend-mode:multiply;}
.animate{
border:1px solid red;
border-radius: 1rem;
width:2rem;
height:2rem;
animation: spin 2s infinite linear;
display:flex;
align-items: space-around;
align-content: stretch;
justify-content: space-around;
}
#keyframes spin {
0% { transform: rotate(0deg); background-color: aqua; }
50% { background-color: yellow; }
100% { transform: rotate(1turn); background-color: aqua; }
}
<div class="animate">•</div>
<div class="box">
<img src="https://placeimg.com/400/200/animals" alt="">
</div>
In this problem, animate's stack order is between box and img because animate use keyframe.I think keyframe change animate's stack order.So,Img cannot blend in box.We can change element's stack order by using z-index.
Solution is img must within box.We have two options.Results will be different where you use z-index.
First option, we can change animate's stack order in animate class.
`
.animate{
position:relative;
z-index:2;
}
`
Result - animate will be front of box with img.
Second option, we can change box's stack order in box class.
`
.box{
position:relative;
z-index:2;
}
`
Result - box with img will be front of animate.
.box {
background-color:yellow;
overflow:hidden;
border-radius:10px;
}
.box img{ mix-blend-mode:multiply}
.animate{
border:1px solid red;
width:30px; height:30px;
position:relative;
z-index:2;
animation: spin 2s infinite linear;
}
#keyframes spin {
0% { transform: rotate(0deg); }
100% { transform: rotate(1turn); }
}
<div class="animate">123</div>
<div class="box">
<img src="https://placeimg.com/400/200/animals" alt="">
</div>
I'm trying to mimic sites like: http://shiz.co/ and http://www.maison-vignaux.com/work
The way the images show up, it's like they're not moving, but more of it gets shown in an interval. I want this type of animation. Right now, my image moves rather than having more of it show up like the sites above.
I have no idea how to accomplish this.
Here's my fiddle: https://jsfiddle.net/z7ukk6kb/ (disregard the name of the animation)
EDIT: problem was the background position on the div. now it does what I want.
<div class="parallax-elem">
<div class="img"></div>
</div>
$('.img').addClass('slide-top');
My CSS:
.slide-top {
-webkit-animation: slide-top 0.5s cubic-bezier(0.250, 0.460, 0.450, 0.940) both;
animation: slide-top 0.5s cubic-bezier(0.250, 0.460, 0.450, 0.940) both;
}
#keyframes slide-top {
0% {
width:0;
}
100% {
width:100%;
}
}
.parallax-elem {
overflow:hidden;
position: absolute;
height:600px;
width:100%;
}
.parallax-elem:after {
content:"";
background-color:#eee;
width:100%;
height:100%;
top:0;
left:0;
right:0;
position: absolute;
z-index:10;
}
.img {
background:url('http://media.nj.com/entertainment_impact_dining/photo/coffee-stock-photo-0e8b300f42157b6f.jpg') no-repeat;
background-size: cover;
background-position: center center;
position: relative;
height: 100%;
z-index:11;
width: 100%;
}
Try removing background-position from .img.
Since you have set background-position: center center, as the width of the div increases during the animation, the background image keeps adjusting to stay centered. That's the reason it keeps moving.
$('.img').addClass('slide-top');
.slide-top {
animation: slide-top 0.5s cubic-bezier(0.250, 0.460, 0.450, 0.940) both infinite;
}
#keyframes slide-top {
0% {
width:0;
}
100% {
width:100%;
}
}
body {
max-width:800px;
margin:0 auto;
position:relative;
}
.parallax-elem {
overflow:hidden;
position: absolute;
height:600px;
width:100%;
}
.parallax-elem:after {
content:"";
background-color:#eee;
width:100%;
height:100%;
top:0;
left:0;
right:0;
position: absolute;
z-index:10;
}
.img {
background:url('http://media.nj.com/entertainment_impact_dining/photo/coffee-stock-photo-0e8b300f42157b6f.jpg') no-repeat;
background-size: cover;
position: relative;
height: 100%;
z-index:11;
width: 100%;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="parallax-elem">
<div class="img"></div>
</div>
The reason this happens is because you use background-position center. And that is exactly what is is doing, it is aligning you image in the center. If you'd change is to background-position: left center, the problem is fixed, as you can see in this fiddle.
You could also remove the background-position entirely, but then you will also loose you vertical alignment, you might not want that.
Also, you can make your animation a whole lot easier, you don't need keyframes:
.img{
width: 0%;
background-position: left center;
animation: width 0.5s cubic-bezier(0.250, 0.460, 0.450, 0.940);
}
.img.slide-top{
width: 100%;
}
I'd like to implement a "funny" Navigation into my website, with perspective and stuff, but, as a beginner, I look at a brick-wall.
I just don't find a way to get the line backface-visibility: hidden; working.
My goal is:
Front:
Back:
The result with the code below is (in rotation-state):
There are plenty of working sample-codes on CodePen, and I tried to figure it out without success. Weird things happened, but never did the backface-visibility of an object get its hidden-state.
I used a great template to work on (designmodo.com) and trimmed it down to this:
HTML
<body>
<div class="poster">
<div class="layer-1">FRONT<img src="images/VS.svg" alt="Front" id="FRONT"></div>
<div class="layer-2">BACK<img src="images/RS.svg" alt="Back" id="BACK"></div>
</div>
</body>
CSS
body {
transform-style:preserve-3d;
transform:perspective(1500px);
}
.poster {
width:510px;
height:310px;
position:absolute;
top:50%;
left:50%;
margin:-156px 0 0 -256px;
border-radius:4px;
box-shadow:0 45px 100px rgba(0,0,0,0.4);
}
.layer-1, .layer-2 {
position:absolute;
top:0;
left:0;
transform:translateZ(10px);
backface-visibility:hidden;
}
.layer-2 {
transform:rotateY(180deg);
}
Please see my pen: https://codepen.io/herrbraun/pen/JKroYa
(the rotation is there only to show the not-working blackface-visibility –– once it works, it'll be interactive)
If somebody could have an eye on what I've got so far, I don't see any typos or syntax-errors, but – what makes the CSS "fail"?
First of all, you have a syntax error:
.layer-1, layer-2 {
should be
.layer-1, .layer-2 {
Also, for this setup to work, you need to set
.poster {
transform-style: preserve-3D;
}
because you have transforms both in the parent and the child, and you want get the backface style to the combination of both. You had already this on body, but this property doesn't inherit.
Your snippet corrected
body {
transform-style:preserve-3d;
transform:perspective(1500px);
}
#keyframes rotating {
from{
transform: rotateY(0deg);
}
to{
transform: rotateY(360deg);
}
}
.poster {
animation: rotating 10s linear infinite;
}
.poster {
width:510px;
height:310px;
position:absolute;
top:50%;
left:50%;
margin: 0 0 0 -256px;
border-radius:4px;
box-shadow:0 45px 100px rgba(0,0,0,0.4);
transform-style: preserve-3D; /* new */
}
.poster .shine {
position:absolute;
top:0;
left:0;
background:-webkit-linear-gradient(0deg,rgba(0,0,0,0) 0%,rgba(0,0,0,0) 60%);
background:linear-gradient(135deg,rgba(0,0,0,0) 0%,rgba(0,0,0,0) 60%);
z-index:100;
}
.layer-1, .layer-2 {
position:absolute;
top:0;
left:0;
transform: translateZ(10px);
-moz-backface-visibility: hidden;
-webkit-backface-visibility: hidden;
backface-visibility: hidden;
-webkit-transition: .1s;
transition: .1s;
}
.layer-1 {background-color: blue; color:white;}
.layer-2 {
background-color: red;
transform:rotateY(180deg);
}
<div class="poster">
<div class="layer-1">FRONT<img src="images/VS.svg" alt="Front" id="FRONT"></div>
<div class="layer-2">BACK<img src="images/RS.svg" alt="Back" id="BACK"></div>
</div>
Try setting the animation to .layer-1 and .layer-2 instead of .poster and set the animation-delay of .layer-2 to -5s
I have a div with an inner span with text. This inside span should be centered vertically and horizontally all the time:
http://jsfiddle.net/QW4Wk/
<div>
<span>Text aligned center</span>
</div>
The div has a transition when the mouse is over, which changes its width and height.
div{
width:200px;
height:200px;
background:black;
position:relative;
-webkit-transition:width 10s,height 10s;
}
span {
position:absolute;
color:white;
bottom:0;
right:0;
}
div:hover{
width:250px;
height:250px;
}
However in Chrome (at least) the text looks choppy while the transition is running. I guess this is because the transition goes 1 by 1px and therefor the "center style" has to go back and forward 1px.
Is there someway to fix this to look smoother, something like subpixel?
Thanks.
try this for absolute centering the text..
span {
margin: auto;
color:white;
text-align:center;
height:10px;
position: absolute;
top: 0; left: 0; bottom: 0; right: 0;
}
and of course lessen your transition speed.
Apply a different change to the span. a transform can be subpixel
div{
width:200px;
height:200px;
background:black;
position:relative;
-webkit-transition:width 10s,height 10s;
}
span {
position:absolute;
color:white;
top:75px;
left:50px;
width: 100px;
transition: -webkit-transform 10s;
-webkit-transform: translate(0px, 0px);
}
div:hover{
width:250px;
height:250px;
}
div:hover span {
-webkit-transform: perspective(999px) translate(25px, 25px);
}
