Rotating background image opposite to direction of div - html

Question [Resolved]: How do I rotate the background image of a circle?
Link: https://codepen.io/Refath/pen/XaoMEj
Hi, I'm trying to rotate the background image of a circle element the opposite direction, but at the same magnitude of rotation, so that the background remains straight relative to the user. I've tried to use css keyframes, but realized this would not be the best idea, and then tried to implement the solution given [here][1], also failing after some tweaks. Thanks; Any help is appreciated (I'm not an advanced web developer, so I don't have much experience with JS, etc.)

How can I rotate an object(div) around a circle margin? Css only

I want to move the blue container around the circle (with it's bottom margin if possible). What I succeded until now is to move it by it's center(still not so smooth).
Does css has any option to translate & rotate in a circle direction? What I tried was to translate and rotate at the same time by using this three points (top, right, and top-right) of the circle, because I only need it to rotate 90 deg.
#mainContent{ position: relative;
display: block;
width: 100vw;
border: none;
margin: 0 auto;
height: 100vh;
overflow: visible;
background: black;
}
#circle{
position: absolute;
left: 50%;
top: 50%;
background: red;
border-radius: 50%;
width: 100px;
height: 100px;
transform: translate(-50%, -50%);
}
.container{
position: absolute;
left: 50%;
top: 50%;
background: pink;
width: 100px;
height: 100px;
transform: translate(-50%, -50%);
}
#element{
position: absolute;
top: 50%;
left: 50%;
width: 20px;
height: 60px;
background: blue;
transform-origin: center;
transform: translate(-50%, -50%);
animation: orbit 3s linear infinite;
}
#keyframes orbit{
0% {
transform-origin: center;
transform: translate(-50%, calc(-50% - 50px)) rotate(0deg);
}
50%{
transform-origin: center;
transform: translate(calc(-50% + 35.35px), calc(-50% - 35.35px)) rotate(45deg);
}
100% {
transform-origin: center;
transform: translate(calc(-50% + 50px), -50%) rotate(90deg);
}
}
*{
margin: 0;
}
<div id="mainContent">
<div class="container"></div>
<div id="circle"></div>
<div id="element"></div>
</div>
You have to play with the transform-origin
#mainContent {
position: relative;
display: block;
width: 100vw;
border: none;
margin: 0 auto;
height: 100vh;
overflow: visible;
background: black;
}
#circle {
position: absolute;
left: 50%;
top: 50%;
background: red;
border-radius: 50%;
width: 100px;
height: 100px;
transform: translate(-50%, -50%);
}
.container {
position: absolute;
left: 50%;
top: 50%;
background: pink;
width: 100px;
height: 100px;
transform: translate(-50%, -50%);
}
#element {
position: absolute;
top: 50%;
left: calc(50% - 10px);
width: 20px;
height: 60px;
background: blue;
transform-origin: top center;
animation: orbit 3s linear infinite;
}
#keyframes orbit {
to {
transform: rotate(360deg);
}
}
* {
margin: 0;
}
<div id="mainContent">
<div class="container"></div>
<div id="circle"></div>
<div id="element"></div>
</div>
If i understand right, you need to set the translate-origin to the side which the blue rectangle reach the center of the red circle, check the snipet:
(hover the red circle to hide the blue rectangle)
div {
position: relative;
width: 200px;
height: 200px;
margin: 10em auto;
}
.round {
border-radius: 100%;
background: red;
}
.round:hover + .rectangle{background:transparent;}
.rectangle {
width: 100%;
height: 20px;
background: blue;
position: absolute;
top: 0;
bottom: 0;
right: 50%;
margin: auto;
transform-origin: right;
transform: rotate(0deg);
animation: orbit 3s linear infinite;
}
.moon{
width:50px;height:50px;
background:white;
border:1px solid gray;
border-radius:100%;
position:absolute;
top:0;
bottom:0;
margin:auto;
}
#keyframes orbit {
0% {
transform: rotate(0deg);
}
50% {
transform: rotate(180deg);
}
100% {
transform: rotate(359deg);
}
}
<div>
<div class="round"></div>
<div class="rectangle">
<div class="moon"></div>
</div>
</div>
Don't center the element but put it on the top side and then adjust the transform-origin to make it at the center of the circle:
#mainContent {
position: relative;
margin: 0 auto;
height: 100vh;
overflow: visible;
background: black;
}
#circle {
position: absolute;
left: 50%;
top: 50%;
background: red;
border-radius: 50%;
width: 100px;
height: 100px;
transform: translate(-50%, -50%);
}
.container {
position: absolute;
left: 50%;
top: 50%;
background: pink;
width: 100px;
height: 100px;
transform: translate(-50%, -50%);
}
#element {
position: absolute;
top: calc(50% - 80px); /* 80 = (60 + 100)/2*/
left: calc(50% - 10px);
width: 20px;
height: 60px;
background: blue;
transform-origin: 50% calc(100% + 20px); /* 20 = (100 - 60)/2 */
animation: orbit 3s linear infinite;
}
#keyframes orbit {
100% {
transform: rotate(360deg);
}
}
* {
margin: 0;
}
<div id="mainContent">
<div class="container"></div>
<div id="circle"></div>
<div id="element"></div>
</div>

How to make 2 circles travelling in opposite directions?

I'm making a HTML program where I want to have two circles traveling on a circular path, in opposite directions. That's the main idea. Here's my code so far (I followed this tutorial on circular movement coding, and stopped right at 8:35 when it's just the red circle in motion):
styles.css:
body{
margin: 0;
padding: 0;
}
.circle{
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
width: 400px;
height: 400px;
background: transparent;
border-radius: 50%;
border: 2px solid #262626;
}
.line{
width: 50%;
height: 2px;
background: transparent;
position: absolute;
top: calc(50% - 1px);
transform-origin: right;
animation: animate 1s linear infinite;
}
.line:before{
content: '';
position: absolute;
width: 20px;
height: 20px;
background: #f00;
border-radius: 50%;
top: -10px;
left: -11px;
}
#keyframes animate{
0%{
transform: rotate(0deg);
}
100%{
transform: rotate(360deg);
}
}
index.html:
<!DOCTYPE html>
<html>
<head>
<title>Two Circles in Circular Motion</title>
<link rel="stylesheet" href="style.css">
</head>
<body>
<div class = "circle">
<div class = "line"></div>
</div>
</body>
</html>
Right now I only have 1 circle. I want to create another one, and animate it so that it travels in the same circular path but in the opposite direction. I'm relatively new to CSS and HTML, so can someone please help? Thanks!
You can optimize your code and use only one div and its pseudo element for the small circles:
.circle {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
width: 400px;
height: 400px;
border-radius: 50%;
border: 2px solid #262626;
/* place both item to the center */
display:grid;
align-content:center;
justify-content:center;
}
.circle::before,
.circle::after {
content: '';
grid-area:1/1; /* both will overlap */
width: 20px;
height: 20px;
background: #f00;
border-radius: 50%;
transform:rotate(0deg) translate(200px) rotate(0deg);
animation:animate 2s linear infinite;
}
.circle::after {
animation-direction:reverse; /* the opposite animation for the after */
background:blue;
}
#keyframes animate {
100% {transform:rotate(360deg) translate(200px) rotate(-360deg);}
}
<div class="circle">
</div>
Another solution is you could have made another line and used
animation-direction: reverse; on it.
Example;
body {
margin: 0;
padding: 0;
}
.circle {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
width: 400px;
height: 400px;
background: transparent;
border-radius: 50%;
border: 2px solid #262626;
}
.line, .line2 {
width: 50%;
height: 2px;
background: transparent;
position: absolute;
top: calc(50% - 1px);
transform-origin: right;
animation: animate 1s linear infinite;
}
.line:before, .line2:before {
content: '';
position: absolute;
width: 20px;
height: 20px;
background: #f00;
border-radius: 50%;
top: -10px;
left: -11px;
}
.line2 {
animation-direction: reverse;
}
#keyframes animate {
0% {
transform: rotate(0deg);
}
100% {
transform: rotate(360deg);
}
}
<div class="circle">
<div class="line"></div>
<div class="line2"></div>
</div>
You also could have created another line (like I did in my example (line2)), and bound a different animation keyframe to it like below;
body {
margin: 0;
padding: 0;
}
.circle {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
width: 400px;
height: 400px;
background: transparent;
border-radius: 50%;
border: 2px solid #262626;
}
.line {
width: 50%;
height: 2px;
background: transparent;
position: absolute;
top: calc(50% - 1px);
transform-origin: right;
animation: animate 1s linear infinite;
}
.line2 {
width: 50%;
height: 2px;
background: transparent;
position: absolute;
top: calc(50% - 1px);
transform-origin: right;
animation: animate2 1s linear infinite;
}
.line:before, .line2:before {
content: '';
position: absolute;
width: 20px;
height: 20px;
background: #f00;
border-radius: 50%;
top: -10px;
left: -11px;
}
#keyframes animate {
0% {
transform: rotate(0deg);
}
100% {
transform: rotate(360deg);
}
}
#keyframes animate2 {
0% {
transform: rotate(360deg);
}
100% {
transform: rotate(0deg);
}
}
<div class="circle">
<div class="line"></div>
<div class="line2"></div>
</div>
There are many possibilities to achieve what you are looking for :)
Because you say you are new to HTML and CSS I figured I'd show you some alternatives.

How could I hide the overflow of my animated circle ripple effect?

I'm trying to get a ripple effect on the bottom left corner. What I would like to see is the ripple effect to only show in the hero area (100% of the retina) and not to overflow into the other section.
I thought I could hide it with 'overflow: hidden' but I seem to be wrong about this.
I'm hoping this explanation of what I want is clear. Let me know if I wasn't.

pure CSS drawing circle animation

I wrote a pure css drawing circle animation, but there's a little white space between the two half circles during the animation. (When the animation ends, they gone.)
Can anyone please tell me why does this happened?
My HTML:
.circle__box {
width: 200px;
height: 200px;
margin: 50px auto;
position: relative;
}
.circle__wrapper {
width: 100px;
height: 200px;
position: absolute;
top: 0;
overflow: hidden;
}
.circle__wrapper--right {
right: 0;
}
.circle__wrapper--left {
left: 0;
}
.circle__whole {
width: 160px;
height: 160px;
border: 20px solid transparent;
border-radius: 50%;
position: absolute;
top: 0;
transform: rotate(-135deg);
}
.circle__right {
border-top: 20px solid teal;
border-right: 20px solid teal;
right: 0;
animation: circleRight 5s linear forwards;
}
.circle__left {
border-bottom: 20px solid teal;
border-left: 20px solid teal;
left: 0;
animation: circleLeft 5s linear forwards;
}
#keyframes circleRight {
0% {
transform: rotate(-135deg);
}
50%,
100% {
transform: rotate(45deg);
}
}
#keyframes circleLeft {
0%,
50% {
transform: rotate(-135deg);
}
100% {
-webkit-transform: rotate(45deg);
}
}
<div class="circle__box">
<div class="circle__wrapper circle__wrapper--right">
<div class="circle__whole circle__right"></div>
</div>
<div class="circle__wrapper circle__wrapper--left">
<div class="circle__whole circle__left"></div>
</div>
</div>
My complete code goes here. Thank you.
Here it is, please check. It was because of you gave .circle-left and .circle-right left:0; and right:0; respectively, change it to left:1px; and right:1px; and you're done...
.circle__box {
width: 200px;
height: 200px;
margin: 50px auto;
position: relative;
}
.circle__wrapper {
width: 100px;
height: 200px;
position: absolute;
top: 0;
overflow: hidden;
}
.circle__wrapper--right {
right: 0;
}
.circle__wrapper--left {
left: 0;
}
.circle__whole {
width: 160px;
height: 160px;
border: 20px solid transparent;
border-radius: 50%;
position: absolute;
top: 0;
transform: rotate(-135deg);
}
.circle__right {
border-top: 20px solid teal;
border-right: 20px solid teal;
right: 1px;
animation: circleRight 5s linear forwards;
}
.circle__left {
border-bottom: 20px solid teal;
border-left: 20px solid teal;
left: 1px;
animation: circleLeft 5s linear forwards;
}
#keyframes circleRight {
0% {
transform: rotate(-135deg);
}
50%,
100% {
transform: rotate(45deg);
}
}
#keyframes circleLeft {
0%,
50% {
transform: rotate(-135deg);
}
100% {
-webkit-transform: rotate(45deg);
}
}
<div class="circle__box">
<div class="circle__wrapper circle__wrapper--right">
<div class="circle__whole circle__right"></div>
</div>
<div class="circle__wrapper circle__wrapper--left">
<div class="circle__whole circle__left"></div>
</div>
</div>
This is my solution:
.circle__wrapper--right { right: 0; margin-right: 20px;}
.circle__wrapper--left { left: 0; margin-left: 20px; }

CSS Transforms Inheritance Issue

The following HTML5 and CSS3 animation is giving me two different issues and I've not been able to find previous answers to the question that have worked on my code. I'm curious if I'm doing something completely wrong here.
I have tried the solutions in this question, and this one with no results.
The two issues:
1.) The moon orbit transforms fine; the moon, as a child element, transforms as well. I attempt to apply the opposite transform but it doesn't appear to have any effect.
2.) I'm trying to alter the z-index so the moon goes behind the planet. The orbit border is temporary so no worries there but no matter what I set the z-index to I can't get the effect.
body {
height: 100%;
top: 0px;
bottom: 0px;
margin-top: 300px;
background-color: #143856;
}
.moonorbit {
position: relative;
top: -249px;
left: 309px;
width: 500px;
height: 500px;
border: 2px solid white;
border-radius: 50%;
-moz-transform: rotateX(75deg);
-webkit-transform: rotateX(75deg);
-o-transform: rotateX(75deg);
-ms-transform: rotateX(75deg);
transform: rotateX(75deg);
}
.mooncontainer {
position: absolute;
top: 175px;
left: 175px;
width: 150px !important;
height: 150px;
-moz-transform: rotateX(-75deg);
-webkit-transform: rotateX(-75deg);
-o-transform: rotateX(-75deg);
-ms-transform: rotateX(-75deg);
transform: rotateX(-75deg);
animation: moon-orbit 10s linear infinite;
}
.moon {
width: 150px !important;
height: 150px;
border-radius: 50%;
background: red url(img/planets_MOON.png) no-repeat;
background-size: cover;
animation: rotate 10s linear infinite;
}
.earth {
position: absolute;
width: 417px;
top: 100px;
left: 350px;
z-index: 0;
height: 209px;
}
.earth .planet {
/*width: 417px !important;

width: 300px !important;
height: 300px;
background: yellow url(img/planets_EARTH.png) no-repeat;
background-size: cover;
border-radius: 50%;
margin: 0 auto;
}
/*Moon Orbit*/
#keyframes moon-orbit {
0% {
transform: rotateZ(0deg) translateX(250px);
}
100% {
transform: rotateZ(360deg) translateX(250px);
}
}
#keyframes rotate {

z-index: 5;
}
100% {

transform: rotateZ(-360deg);

About your first issue, you are applying the technique ok. But there are 2 transformations that you need to correct, the one from the animation of the circle, that you have done, and the one from the inclination of the orbit (the rotateX(75deg)
This would be your demo with the correction applied
body {
height: 60%;
top: 0px;
bottom: 0px;
margin-top: 300px;
background-color: #143856;
}
.moonorbit {
position: relative;
top: -300px;
left: 209px;
width: 500px;
height: 500px;
border: 2px solid white;
border-radius: 50%;
transform: rotateX(75deg);
transform-style: preserve-3d;
}
.mooncontainer {
position: absolute;
top: 175px;
left: 175px;
width: 150px !important;
height: 150px;
-webkit-transform: rotateX(-75deg);
transform: rotateX(-75deg);
animation: moon-orbit 10s linear infinite;
transform-style: preserve-3d;
}
.moon {
width: 150px !important;
height: 150px;
border-radius: 50%;
background-color: white;
background-size: cover;
animation: rotate 10s linear infinite;
transform-style: preserve-3d;
}
.earth {
position: absolute;
width: 417px;
top: 100px;
left: 250px;
z-index: 0;
height: 209px;
}
.earth .planet {
/*width: 417px !important;
height: 417px;*/
width: 300px !important;
height: 300px;
background-color: lightgreen;
background-size: cover;
border-radius: 50%;
margin: 0 auto;
}
/*Moon Orbit*/
#keyframes moon-orbit {
0% {
transform: rotateZ(0deg) translateX(250px);
}
100% {
transform: rotateZ(360deg) translateX(250px);
}
}
#keyframes rotate {
0% {
transform: rotateZ(0deg) rotateX(-75deg); /* added rotateX(-75deg) to compensate */
}
100% {
transform: rotateZ(-360deg) rotateX(-75deg);
}
}
<div class="earth">
<div class="planet"></div>
</div>
<div class="moonorbit">
<div class="mooncontainer">
<div class="moon"></div>
</div>
</div>
About the second issue, your best bet is to work all the time in 3d, so it will be automatically solved. Another technique that makes it simpler is to chain the transforms. In my demo I have chained everything, so it's easier to get the control (and you have a simpler HTML
body {
height: 60%;
top: 0px;
bottom: 0px;
background-color: #143856;
}
.moon {
width: 150px;
height: 150px;
border-radius: 50%;
background: url(http://i.stack.imgur.com/L3IE5.jpg);
background-size: 120%;
background-position: center center;
animation: rotate 10s linear infinite;
transform-style: preserve-3d;
margin: auto;
position: absolute;
left: 0px;
right: 0px;
top: 0px;
bottom: 0px;
}
.earth {
position: absolute;
width: 300px;
height: 300px;
background: url(http://i.stack.imgur.com/5sqwZ.jpg);
background-size: 140%;
background-position: center center;
border-radius: 50%;
margin: 100px 200px;
perspective: 1500px;
transform-style: preserve-3d;
}
#keyframes rotate {
0% {
transform: rotateX(-75deg) rotateZ(0deg) translateX(300px) rotateZ(0deg) rotateX(75deg);
}
100% {
transform: rotateX(-75deg) rotateZ(-360deg) translateX(300px) rotateZ(360deg) rotateX(75deg);
}
}
<div class="earth">
<div class="moon"></div>
</div>
Trying to fix this with z-index will end in failure 70% all the time. lol See what I did there? Anyways, your best bet is to do this with a keyframes. Create a keyframe to draw out your path and to be honest you will need other things that would take a while to explain but How about I'll post my code here and the DEMO and you will be able to see the difference?

And some simple jQuery to get the 3D effect so it looks 2D but moves 3D
$(window).load(function(){
var body = $("body"),
universe = $("#universe"),
solarsys = $("#solar-system");
var init = function() {
body.removeClass('view-2D opening').addClass("view-3D").delay(2000).queue(function() {
$(this).removeClass('hide-UI').addClass("set-speed");
$(this).dequeue();
});
};
init();
});
Here is a DEMO
I think if you use my code you'll probably be better off than fixing yours. Just a suggestion ;)
