How to create a spinning semi circle around text - javascript

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" />

Alignment of element in HTML/CSS

I have the following code:
scroll {
left: 50%;
transform: translateY(0%) rotate(45deg);
opacity: 0;
}
#keyframes scrolldown1 {
0% {
transform: translateY(20%) rotate(45deg);
opacity: 0.7;
}
50% {
transform: translateY(0%) rotate(45deg);
opacity: 0.2;
}
100% {
transform: translateY(20%) rotate(45deg);
opacity: 0.7;
}
}
<scroll style="width: 2em; height: 2em; background-color: transparent; z-index: 80;
bottom: 25px; border-width: 0 0.25em 0.25em 0; border-style: solid; border-color: black; position: absolute; animation: scrolldown1 1.2s ease-in-out infinite 0.15s;"></scroll>
<scroll style="width: 2em; height: 2em; background-color: transparent; z-index: 80;
bottom: 40px; position: absolute; border-width: 0 0.25em 0.25em 0; border-style: solid; border-color: black; animation: scrolldown1 1.2s ease-in-out infinite;"></scroll>
This is basically a scroll button and on my end the output is looking like this:
As you can see the alignment of the scroll button is slightly off and I would like it to be right on top of the MY STORY text or be centered. How would I achieve this task?
The code of the MY STORY text is as follows:
section {
padding: 60px 0;
overflow: hidden;
}
.section-title {
text-align: center;
padding-bottom: 30px;
}
.section-title h2 {
font-size: 32px;
font-weight: bold;
text-transform: uppercase;
margin-bottom: 20px;
padding-bottom: 20px;
position: relative;
color: #45505b;
}
.section-title h2::before {
content: '';
position: absolute;
display: block;
width: 120px;
height: 1px;
background: #ddd;
bottom: 1px;
left: calc(50% - 60px);
}
.section-title h2::after {
content: '';
position: absolute;
display: block;
width: 40px;
height: 3px;
background: #0563bb;
bottom: 0;
left: calc(50% - 20px);
}
<div class="section-title">
<h2>My Story</h2>
</div>
How would I achieve this task?
Basically, the scroll button should be right on top of the text
Notice that your .section-title's pseudo-elements have their left property set using calc and taking into account half of each element's width:
.section-title h2::before {
...
width: 120px;
...
left: calc(50% - 60px);
}
.section-title h2::after {
...
width: 40px;
...
left: calc(50% - 20px);
}
But the left property in your scroll declaration does not use calc. Therefore one possible fix would be to use it. Since each scroll element has a width of 2em, half of it would be 1em. So:
scroll {
/* left: 50%; */ /* remove this line */
left: calc(50% - 1em); /* add this line */
transform: translateY(0%) rotate(45deg);
opacity: 0;
}
See demo below.
#container {
position: relative;
height: 5em;
}
scroll {
/* left: 50%; */ /* remove this line */
left: calc(50% - 1em); /* add this line */
transform: translateY(0%) rotate(45deg);
opacity: 0;
}
.first-scroll {
width: 2em;
height: 2em;
background-color: transparent;
z-index: 80;
bottom: 25px;
border-width: 0 0.25em 0.25em 0;
border-style: solid;
border-color: black;
position: absolute;
animation: scrolldown1 1.2s ease-in-out infinite 0.15s;
}
.second-scroll {
width: 2em;
height: 2em;
background-color: transparent;
z-index: 80;
bottom: 40px;
position: absolute;
border-width: 0 0.25em 0.25em 0;

PS.: Unless you're using this positioned layout for browser compatibility reasons, you probably should consider using more modern layout modules, such as flexbox or grid, your life would be much easier.

Blur background when loading symbol opens in Javascript

I have loading symbol which works fine, But when loading symbol opens i can see background and user can edit textbox in backend. I need to disable background, until loading completes. Need to blur background. Tried overlay. Nothing seems to work.
Here is my code.
<style>
.lds-dual-ring.hidden {
display: none;
}
.overlay {
background: rgba(0,0,0,.5);
height: 100vh;
left: 50%;
opacity: 1;
position: fixed;
top: 50%;
transition: all 0.5s;
width: 100%;
z-index: 99000;
}
.lds-dual-ring {
display: inline-block;
height: 80px;
width: 80px;
}
.lds-dual-ring:after {
animation: lds-dual-ring 1.2s linear infinite;
border: 6px solid #fff;
border-color: #fff transparent #fff transparent;
border-radius: 50%;
content: " ";
display: block;
height: 64px;
margin: 5% auto;
width: 64px;
}
##keyframes lds-dual-ring {
0% {
transform: rotate(0deg);
}
100% {
transform: rotate(360deg);
}
}
</style>
<div id="loader1" class="lds-dual-ring hidden overlay"></div>
$('#loader1').removeClass('hidden'); //to show
I've recreated a working example of the code you've provided.
Your div contains both overlay and lsd-dual-ring classes. IMO, what you want to achieve is to have the loader ring is inside the overlay div and position at the center of the screen.
.lds-dual-ring.hidden {
display: none;
}
.overlay {
background: rgba(0,0,0,.5);
height: 100vh;
left: 0;
opacity: 1;
position: fixed;
top: 0;
transition: all 0.5s;
width: 100%;
z-index: 99000;
}
.lds-dual-ring {
display: inline-block;
height: 80px;
width: 80px;
top: 50%;
left: 50%;
position: fixed;
}
.lds-dual-ring:after {
animation: lds-dual-ring 1.2s linear infinite;
border: 6px solid #fff;
border-color: #fff transparent #fff transparent;
border-radius: 50%;
content: " ";
display: block;
height: 64px;
margin: 5% auto;
width: 64px;
}
##keyframes lds-dual-ring {
0% {
transform: rotate(0deg);
}
100% {
transform: rotate(360deg);
}
}
<div class="overlay">
<div id="loader1" class="lds-dual-ring"></div>
</div>

cannot restart the css animation onclick in chrome

I have search on the topic about restarting animation and that can be done by remove and add class again. But when I test it myself with the same method, I found that it doesn't work in many browsers. It only work in Edge. Is there something I did wrong?
here is the html:
function(elem) {
elem.classList.remove("animation");
setTimeout(function(){
elem.classList.add("animation");
elem.style.animationName = "transformOuter";
elem.style.webkitAnimationName = "transformOuter";},1)
}
div.wrapperL {
float: left;
width: 40px;
height: 38px;
background: rgb(255, 255, 255);
position: relative;
border: 1px solid white;
margin: 0 1px 5px 0;
}
div.wrapperLeft {
width: 40px;
height: 38px;
background: white;
position: relative;
border: 1px solid lightgrey;
}
div.animation {
-webkit-animation-name: none;
-webkit-animation-duration: 5s;
-webkit-animation-iteration-count: 1;
animation-name: none;
animation-duration: 5s;
animation-iteration-count: 1;
}
#-webkit-keyframes transformOuter {
0% {background-color: #FFFFFF; width: 40px; height: 38px; left: 0px; top: 0px; z-index: 10;}
40% {width: 120px; height: 114px; left: -40px; top: -38px; font-size: 30px;}
60% {width: 120px; height: 114px; left: -40px; top: -38px; font-size: 30px; transform: rotateY(0deg); }
100% {width: 0px; height: 0px; left: 20px; top: 19px; background-color: #FFFFFF; transform: rotateY(360deg); z-index: 0; font-size: 0px;}
}
<div class = "wrapperL">
<div class= "wrapperLeft" onclick = functionAnime(this)></div>
</div>
I also have another keyframe without -webkit- but same thing inside.The animation do trigger once in chrome but when I click again, nothings happen.
You have to remove style as well same as you did with class see working example: And yes your function name was incorrect I assumed it was a typo.
function functionAnime(elem) {
elem.classList.remove("animation");
elem.style = '';
setTimeout(function(){
elem.classList.add("animation");
elem.style.animationName = "transformOuter";
elem.style.webkitAnimationName = "transformOuter";
},100)
}
div.wrapperL{
float: left ;
width: 40px;
height: 38px;
background: rgb(255, 255, 255);
position: relative;
border: 1px solid white;
margin: 0 1px 5px 0;}
div.wrapperLeft{
width: 40px;
height: 38px;
background: white;
position: relative;
border: 1px solid lightgrey; }
div.animation{
-webkit-animation-name: none;
-webkit-animation-duration: 5s;
-webkit-animation-iteration-count: 1;
animation-name: none;
animation-duration: 5s;
animation-iteration-count: 1;}
#-webkit-keyframes transformOuter{
0% { background-color: #FFFFFF; width: 40px; height: 38px; left: 0px; top: 0px; z-index: 10;}
40% { width: 120px; height: 114px; left: -40px; top: -38px; font-size: 30px;}
60% { width: 120px; height: 114px; left: -40px; top: -38px; font-size: 30px; transform: rotateY(0deg); }
100% { width: 0px; height: 0px; left: 20px; top: 19px; background-color: #FFFFFF; transform: rotateY(360deg); z-index: 0; font-size: 0px;}}
<div class = "wrapperL">
<div class= "wrapperLeft animation" onclick = functionAnime(this)></div>
</div>

Create Progress wheel in CSS

I want to create a progress wheel in html and css, if necessary than jQuery also. I create a wheel but problem is that how can I set the length of the borders according to given percentage.
Here is Code:
.loader {
border: 16px solid #f3f3f3;
border-radius: 50%;
border-top: 16px solid #3498db;
width: 120px;
height: 120px;
}
<div class="loader"></div>
It create a circle and blue border on it but I want like the below image.
Here is a radial progress bar that i made. I have updated it to suit your needs.
The fill percentage is determined by the transform rotate value given to .pure-css .semi.right .circle and .pure-css .semi.left .circle
.pure-css {
width: 300px;
height: 300px;
border-radius: 50%;
background: #fff;
position: relative;
color: #fff;
}
.pure-css .semi {
width: 50%;
height: 100%;
position: relative;
display: inline-block;
float: left;
overflow: hidden;
z-index:2;
transform:rotate(30deg)
}
.pure-css .semi.left{
transform-origin:100% 50%;
}
.pure-css .semi.right{
transform-origin:0% 50%;
}
.pure-css .semi.right .circle {
border-top-left-radius: 150px;
border-bottom-left-radius: 150px;
border-right: 0;
transform: rotate(181deg) translate(-100%, 0);
animation: rotate 4s linear forwards;
transform-origin: 0% 50%;
}
.pure-css .semi.left .circle {
border-top-right-radius: 150px;
border-bottom-right-radius: 150px;
border-left: 0;
transform: rotate(36deg) translate(100%, 0);
animation: rotate2 4s linear forwards;
transform-origin: 100% 50%;
animation-delay: 42s;
}
.pure-css .semi .circle {
width: 100%;
height: 100%;
box-sizing: border-box;
border: 50px solid #4ec9aa;
}
.pure-css .text {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
display: inline-block;
overflow: hidden;
font-size: 28px;
color:#28645d;
text-align:center;
}
.pure-css .shade {
width: 100%;
height: 100%;
transform:scale(.9,.9);
border-radius: 50%;
box-sizing: border-box;
border: 30px solid #e7ebee;
}
<div class="rp">
<div class="pure-css">
<div class="semi left">
<div class="circle"></div>
</div>
<div class="semi right">
<div class="circle"></div>
</div>
<div class="text">
<span class="num">Goal<br><b>20,000$</b></span>
</div>
<div class="shade"></div>
</div>
</div>
To change the fill value give
.pure-css .semi.left .circle{
transform: rotate(xdeg) translate(-100%, 0);
}
.pure-css .semi.right.circle{
transform: rotate(xdeg) translate(-100%, 0);
}
where x is a value between 0 and 180 (optional) giving 180 to .semi.right will fill half the circle and 180 to .semi-left will fill the full circle.
To fill according to a percentage value,for filling < 50% set the transform of .semi.right .circle to percentage * 360 / 100 deg and for filling > 50% set the transform of .semi.left .circle to 180 - (percentage * 360/100) deg.
For determining the start and end position of the fill value
.pure-css .semi {
transform:rotate(xdeg)
}

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>
