How to create a spinning semi circle around text

I have a semi circle on the center of my page, which I want to be able to spin, I'm able to do some part of it by adjusting the width but I want a way to make it spin a complete 360degrees. If possible, I want to be able to accomplish it using only css, however if required I don't mind vanilla js (no Jquery).
body {
background-color: lightblue;
}
#txt {
position: fixed;
left: 50%;
transform: translate(-50%, 0);
top: 40%;
font-size: 30px;
color: white;
}
#spinCircle {
position: fixed;
left: 50%;
top: 15%;
height: 50vh;
width: 50px;
border-radius: 0 150px 150px 0;
border-color: black;
color: black;
border-style: solid;
border-left-style: none;
/*background-color: black;*/
animation: spinning infinite;
animation-duration: 3s;
}
#keyframes spinning {
from {
width: 50px
}
to {
width: 0px;
z-index: -5;
}
}
<div id="txt">Hello</div>
<div id="spinCircle" />

Is this what you want?
body {
background-color: lightblue;
}
#txt {
position: fixed;
left: 50%;
transform: translate(-50%, 0);
top: 40%;
font-size: 30px;
color: white;
}
#spinCircle {
position: fixed;
left: 50%;
top: 15%;
height: 50vh;
width: 50px;
border-radius: 0 150px 150px 0;
border-color: black;
color: black;
border-style: solid;
border-left-style: none;
transform-origin: left;
/*background-color: black;*/
animation: spinning infinite;
animation-duration: 3s;
}
#keyframes spinning {
from {
transform: rotateY(0deg);
}
to {
transform: rotateY(180deg);
z-index: -5;
}
}
<div id="txt">Hello</div>
<div id="spinCircle" />

If I understand correctly you want the semicircle to revolve around your "hello" text. If so, you could use the transform: rotateY() style to spin your circle. If you do this, you can add your width to the circle div, as well as set the transform-origin to be the left-side of your element so that you rotate around the left-side of your semi-circle and not the center:
transform-origin: left;
width: 50px;
See example below:
body {
background-color: lightblue;
}
#txt {
position: fixed;
left: 50%;
transform: translate(-50%, 0);
top: 40%;
font-size: 30px;
color: white;
}
#spinCircle {
position: fixed;
left: 50%;
top: 15%;
height: 50vh;
width: 200px;
border-radius: 0 150px 150px 0;
border-color: black;
color: black;
border-style: solid;
border-left-style: none;
animation: spinning linear infinite;
animation-duration: 3s;
transform-origin: left;
width: 50px;
}
#keyframes spinning {
from {
transform: rotateY(0);
}
to {
transform: rotateY(360deg);
}
}
<div id="txt">Hello</div>
<div id="spinCircle" />

So to restate my question, How do I make the turkey jump on the click. so in more of technical terms how do i activate the keyframes with an onclick.
Finally if My code Looks weird, please tell me. Everyone has been saying, fix your code but I do not know how.

Ok, so I'm not proud of what I've done, but I changed up a couple necessary things (like adding id properties and renaming the function) and then wrapped classList.toggle in a setTimeout and it worked. LOL. Please understand that this is all really a bad way to make a Turkey jump, but for the purposes of your question, I got the code to work.

Changing the border colour of 4 circles one after the other?

I have 4 rings of circles that are white and I want one of them to change blue for 1 second, the next one for one second, and so on, totalling 4 seconds. I was thinking of trying this with just CSS animations but I think I'll need JavaScript.. any ideas on how to achieve this? Thanks!
Example: http://imgur.com/a/h0Wy0
HTML:
<div class="circles">
<div class="circle c1">
<div class="circle c2">
<div class="circle c3">
<div class="circle c4"></div>
</div>
</div>
</div>
</div>
CSS:
.circle {
border-radius: 50%;
background: transparent;
border: 10px solid white;
width: 300px;
height: 300px;
margin: 0 auto;
display: flex;
justify-content: center;
align-items: center;
max-width: 100%;
}
.c2 {
width: 250px;
height: 250px;
border-color: white;
}
.c3 {
width: 200px;
height: 200px;
border-color: white;
}
.c4 {
width: 150px;
height: 150px;
}
Here is the JSFiddle: https://jsfiddle.net/ydb48372/3/

You can do this with just css animations. First create animation of 4s duration that sets border-color to blue for 1s or 25% of time of those 4 seconds and the rest of animation returns border-color to gray or 75% of full animation time. Now you just need to use animation-delay on each circle so that animation on one circle starts after 1s when color from previous circle has changed to gray.
.circles {
position: relative;
min-height: 100vh;
}
.circle {
border-radius: 50%;
border: 10px solid gray;
display: inline-block;
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
animation-duration: 4s;
animation-name: changeColor;
animation-iteration-count: infinite;
}
.c1 {
height: 300px;
width: 300px;
}
.c2 {
height: 250px;
width: 250px;
animation-delay: 1s;
}
.c3 {
height: 200px;
width: 200px;
animation-delay: 2s;
}
.c4 {
height: 150px;
width: 150px;
animation-delay: 3s;
}
#keyframes changeColor {
0% {
border-color: #1C50A8;
}
24% {
border-color: #1C50A8;
}
25% {
border-color: gray;
}
100% {
border-color: gray;
}
}
<div class="circles">
<div class="circle c1">
<div class="circle c2">
<div class="circle c3">
<div class="circle c4"></div>
</div>
</div>
</div>
</div>

You can use css3 key frames to achieve what you are looking for. You might have to play with the numbers to get the exact timings you want but it should be achievable.
div {
-webkit-animation: mymove 5s infinite; /* Safari 4.0 - 8.0 */
animation: mymove 5s infinite;
}
/* Safari 4.0 - 8.0 */
#-webkit-keyframes mymove {
0% {border-color: white;}
100% {border-color: blue;}
}
/* Standard syntax */
#keyframes mymove {
0% {border-color: white;}
100% {border-color: blue;}
}

Using animation-delay like a commentator mentions is correct.
.circle {
border-radius: 50%;
background: transparent;
border: 10px solid white;
width: 300px;
height: 300px;
margin: 0 auto;
display: flex;
justify-content: center;
align-items: center;
max-width: 100%;
}
.c2 {
width: 250px;
height: 250px;
border-color: white;
}
.c3 {
width: 200px;
height: 200px;
border-color: white;
}
.c4 {
width: 150px;
height: 150px;
}
.c1, .c2, .c3, .c4 {
animation: 400ms change-border-color forwards;
}
.c2 {
animation-delay: 450ms;
}
.c3 {
animation-delay: 900ms;
}
.c4 {
animation-delay: 1350ms;
}
#keyframes change-border-color {
from { border-color: white; }
to { border-color: blue; }
}
<div class="circles">
<div class="circle c1">
<div class="circle c2">
<div class="circle c3">
<div class="circle c4"></div>
</div>
</div>
</div>
</div>

Refer animation and animation-delay property in css
animation: animate 1s;
animation-delay: 1s;

Spin a div but make its content not go upside down

Is there a way to make a div spin, aswell as its content, but make the content not go upside-down while rotating ?
What I mean is that the div-childs would follow the rotation of the mother-div spinning, but while remaining in the same direction (top on top, bottom on bottom).
My english isn't goog enough to articulate properly what I want to do, so here is an exemple :
.spin {
margin: 50px;
width: 200px;
height: 200px;
background: orange;
animation: spin 10s infinite linear;
}
#div1 {
border: 1px solid blue;
width: 50px;
height: 50px;
}
#div2 {
border: 1px solid red;
width: 50px;
height: 50px;
position: absolute;
top: 0;
right: 0;
}
#div3 {
border: 1px solid black;
width: 50px;
height: 50px;
position: absolute;
bottom: 0;
left: 0;
}
#div4 {
border: 1px solid green;
width: 50px;
height: 50px;
position: absolute;
bottom: 0;
right: 0;
}
.spin:hover {
animation-play-state: paused;
}
#keyframes spin {
0% {
transform: rotate(0deg);
}
100% {
transform: rotate(359deg);
}
}
<div class="spin">
<div id="div1">hello
</div>
<div id="div2">hello
</div>
<div id="div3">hello
</div>
<div id="div4">hello
</div>
</div>
In the exemple above, the child divs are following the rotation and the spin.
I would like them not to "spin upside-down" and just follow the rotation.
I've seen these type of animation in several websites but I can't recall where exactly.
Is there a way to do this in css/js/jquery/php... ?

You can apply the same animation to the four children, but in reverse. That way, the rotation of the children counteract the rotation of the parent and the children remain upright.
For clarity, I've used animation-direction to reverse the animation:
animation-direction: reverse;
But you could include the direction in your animation shorthand, like:
animation: spin 10s reverse infinite linear;
Here's an example:
.spin {
margin: 50px;
width: 200px;
height: 200px;
background: orange;
animation: spin 10s infinite linear;
}
.spin div {
width: 50px;
height: 50px;
animation: spin 10s infinite linear;
animation-direction: reverse;
}
#div1 {
border: 1px solid blue;
}
#div2 {
border: 1px solid red;
position: absolute;
top: 0;
right: 0;
}
#div3 {
border: 1px solid black;
position: absolute;
bottom: 0;
left: 0;
}
#div4 {
border: 1px solid green;
position: absolute;
bottom: 0;
right: 0;
}
.spin:hover,
.spin:hover div {
animation-play-state: paused;
}
#keyframes spin {
0% {
transform: rotate(0deg);
}
100% {
transform: rotate(359deg);
}
}
<div class="spin">
<div id="div1">hello</div>
<div id="div2">hello</div>
<div id="div3">hello</div>
<div id="div4">hello</div>
</div>

Following #showdev answer, if you want the borders around the inner divs to follow the spin of the outer block and only make the text inside to stay "fixed" in position - you can use a bit of jQuery for that:
$('.spin div').each(function() {
$(this).contents().wrap('<span></span>');
});
I also added a bit of css, you can check inside the snippet:
$('.spin div').each(function() {
$(this).contents().wrap('<span></span>');
});
.spin {
margin: 50px;
width: 200px;
height: 200px;
background: orange;
animation: spin 10s infinite linear;
}
.spin div {
text-align: center;
line-height: 50px;
}
.spin div span {
animation: spin 10s infinite linear;
animation-direction:reverse;
display: inline-block;
}
#div1 {
border: 1px solid blue;
width: 50px;
height: 50px;
}
#div2 {
border: 1px solid red;
width: 50px;
height: 50px;
position: absolute;
top: 0;
right: 0;
}
#div3 {
border: 1px solid black;
width: 50px;
height: 50px;
position: absolute;
bottom: 0;
left: 0;
}
#div4 {
border: 1px solid green;
width: 50px;
height: 50px;
position: absolute;
bottom: 0;
right: 0;
}
.spin:hover, .spin:hover span {
animation-play-state: paused;
}
#keyframes spin {
0% {
transform: rotate(0deg);
}
100% {
transform: rotate(359deg);
}
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="spin">
<div id="div1">hello</div>
<div id="div2">hello</div>
<div id="div3">hello</div>
<div id="div4">hello</div>
</div>

I understood you also wanted each of 4 elements to stay in the area of their corners. This might need some extra animation to have them run around the parent edges.
Below the idea of what i understood:
.spin {
margin: 50px;
width: 200px;
height: 200px;
background: orange;
position: relative;
animation: spin 10s infinite linear;
}
.spin div {
width: 50px;
height: 50px;
}
#div1 {
border: 1px solid blue;
animation: spin1 10s infinite linear;
position: absolute;
top: 0;
left: 0;
}
#div2 {
animation: spin2 10s infinite linear;
border: 1px solid red;
position: absolute;
top: 0;
right: 0;
}
#div3 {
animation: spin3 10s infinite linear;
border: 1px solid black;
position: absolute;
bottom: 0;
left: 0;
}
#div4 {
animation: spin4 10s infinite linear;
border: 1px solid green;
position: absolute;
bottom: 0;
right: 0;
}
.spin:hover,
.spin:hover div {
animation-play-state: paused!important;/* or used id and several selectors to avoid the important and overide div#div1 {...}*/
}
#keyframes spin {
0% {
transform: rotate(0deg);
}
100% {
transform: rotate(359deg);
}
}
#keyframes spin1 {
0% {
transform: rotate(0deg);
}
25% {
top: 150px;
left: 0
}
50% {
left: 150px;
top: 150px
}
75% {
left: 150px;
top: 0;
}
100% {
transform: rotate(-359deg);
}
}
#keyframes spin2 {
0% {
transform: rotate(0deg);
}
25% {
top: 0;
right: 150px
}
50% {
right: 150px;
top: 150px
}
75% {
top: 150px;
right: 0;
}
100% {
transform: rotate(-359deg);
}
}
#keyframes spin3 {
0% {
transform: rotate(0deg);
}
25% {
bottom: 0;
left: 150px
}
50% {
left: 150px;
bottom: 150px
}
75% {
bottom: 150px;
left: 0;
}
100% {
transform: rotate(-359deg);
}
}
#keyframes spin4 {
0% {
transform: rotate(0deg);
}
25% {
right: 0;
bottom: 150px
}
50% {
right: 150px;
bottom: 150px
}
75% {
right: 150px;
bottom: 0;
}
100% {
transform: rotate(-359deg);
}
}
<div class="spin">
<div id="div1">top left</div>
<div id="div2">top right</div>
<div id="div3">bottom left</div>
<div id="div4">bottom right</div>
</div>

Add this rule to each numbered div:
counterspin 10s infinite linear;
and then this keyframes animation
#keyframes counterspin {
0% {
transform: rotate(0deg);
}
100% {
transform: rotate(-359deg);
}
}

.spin {
margin: 50px;
width: 200px;
height: 200px;
background: orange;
animation: spin 10s infinite linear;
position:relative;
}
.spin div {
margin:10px;
animation: spin 10s infinite ease-in-out;
animation-direction: reverse;
}
#div1 {
border: 1px solid blue;
width: 50px;
height: 50px;
position:absolute;
top:0;
left:0;
}
#div2 {
border: 1px solid red;
width: 50px;
height: 50px;
position: absolute;
top: 0;
right: 0;
}
#div3 {
border: 1px solid black;
width: 50px;
height: 50px;
position: absolute;
bottom: 0;
left: 0;
}
#div4 {
border: 1px solid green;
width: 50px;
height: 50px;
position: absolute;
bottom: 0;
right: 0;
}
.spin:hover {
animation-play-state: paused;
}
.spin:hover div {
animation-play-state: paused;
}
#keyframes spin {
0% {
transform: rotate(0deg);
}
100% {
transform: rotate(359deg);
}
}
<div class="spin">
<div id="div1">hello
</div>
<div id="div2">hello
</div>
<div id="div3">hello
</div>
<div id="div4">hello
</div>
</div>
you may try this
.spin {
margin: 50px;
width: 200px;
height: 200px;
background: orange;
animation: spin 10s infinite linear;
position:relative;
}
.spin div {
margin:10px;
animation: spin 10s infinite ease-in-out;
animation-direction: reverse;
}
#div1 {
border: 1px solid blue;
width: 50px;
height: 50px;
position:absolute;
top:0;
left:0;
}
#div2 {
border: 1px solid red;
width: 50px;
height: 50px;
position: absolute;
top: 0;
right: 0;
}
#div3 {
border: 1px solid black;
width: 50px;
height: 50px;
position: absolute;
bottom: 0;
left: 0;
}
#div4 {
border: 1px solid green;
width: 50px;
height: 50px;
position: absolute;
bottom: 0;
right: 0;
}
.spin:hover {
animation-play-state: paused;
}
.spin:hover div {
animation-play-state: paused;
}
#keyframes spin {
0% {
transform: rotate(0deg);

}

CSS3 or Javascript - Simple Fill Animation

I'm trying create a simple animation that when a user hovers over an element, another element contained within it fills its parent. Currently, I have a JSFiddle that does just that.
BUT, I want to finish this with a few other features that I'm not sure I can actually do in CSS3.
I'm trying to find a way to, upon having the inner circle COMPLETELY fill its parent, (ie when its width/height = 300px), I'd like the fill to pause and not disappear after the animation is complete.
When a user moves their mouse outside the :hover range, I would like the animation to reverse direction as opposed to abruptly stopping.
I've gotten this far with CSS3 but am not sure I can implement these 2 features without resorting to Javascript. Does anyone know of a way of doing this entirely in CSS3/does anyone know if it is possible to do these last two features in CSS3, because I can't seem to find anything.
.circle {
width: 300px;
height: 300px;
background-color: white;
border: 1px solid #000000;
overflow: hidden;
border-radius: 150px;
-moz-border-radius: 150px;
-webkit-border-radius: 150px;
}
.filler {
width: 0px;
height: 0px;
background-color: red;
border: none;
position: relative;
left: 50%;
top: 50%;
border-radius: 150px;
-mox-border-radius: 150px;
-webkit-border-radius: 150px;
animation: empty 1s;
}
.circle:hover .filler {
animation: fill 2s;
-moz-animation: fill 2s;
-webkit-animation: fill 2s;
background-color: blue;
}
#keyframes fill
{
from {background: red; height: 0px; width: 0px;}
to {background: green; height: 300px; width: 300px; top: 0%; left: 0%;}
}
#-moz-keyframes fill /* Firefox */
{
from {background: red; height: 0px; width: 0px;}
to {background: green; height: 300px; width: 300px; top: 0%; left: 0%;}
}
#-webkit-keyframes fill /* Safari and Chrome */
{
from {background: red; height:0px; width:0px;}
to {background: green; height: 300px; width: 300px; top: 0%; left: 0%;}
}
#keyframes empty
{
to {background: red; height: 0px; width: 0px; top: 50%; left: 50%;}
}
#-moz-keyframes empty
{
to {background: red; height: 0px; width: 0px; top: 50%; left: 50%;}
}
#-webkit-keyframes empty
{
to {background: red; height: 0px; width: 0px; top: 50%; left: 50%;}
}
JS Fiddle

You don't need keyframes for this simple animation. Here is CSS you need:
.circle {
position: relative;
width: 300px;
height: 300px;
background-color: white;
border: 1px solid #000000;
border-radius: 150px;
overflow: hidden;
}
.filter {
position: absolute;
top: 50%;
left: 50%;
width: 0;
height: 0;
background-color: red;
border-radius: 0px;
-webkit-transition: all 1s;
-moz-transition: all 1s;
-o-transition: all 1s;
transition: all 1s;
}
.circle:hover .filter {
top: 0;
left: 0;
width: 100%;
height: 100%;
border-radius: 150px;
background-color: blue;
}
and HTML:
<div class="circle">
<div class="filter"></div>
</div>
