Circular percent progress bar - html

Question

I would like to have an percent circle indicator on my site:
In this case it's showing 75%. How should this be done? I have the yellow circle in a image-file, but if it's easier to, some how, do it all using CSS, that's okay with me.

Answer 1

Considering the shape of the progress bar (rounded end/start) I would suggest using SVG.
DEMO: Radial progress bar
In the following example, the progress is animated with the stroke-dasarray attribute and the % numbers are incremented with jQuery:
var count = $(('#count'));
$({ Counter: 0 }).animate({ Counter: count.text() }, {
duration: 5000,
easing: 'linear',
step: function () {
count.text(Math.ceil(this.Counter)+ "%");
}
});
body{text-align:center;font-family: 'Open Sans', sans-serif;}
svg{width:25%;}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<svg id="animated" viewbox="0 0 100 100">
<circle cx="50" cy="50" r="45" fill="#FDB900"/>
<path fill="none" stroke-linecap="round" stroke-width="5" stroke="#fff"
stroke-dasharray="251.2,0"
d="M50 10
a 40 40 0 0 1 0 80
a 40 40 0 0 1 0 -80">
<animate attributeName="stroke-dasharray" from="0,251.2" to="251.2,0" dur="5s"/>
</path>
<text id="count" x="50" y="50" text-anchor="middle" dy="7" font-size="20">100%</text>
</svg>
Unfortunatly IE doesn't support svg SMIL animations. To achieve the same result with IE support, you can use a library like snap.svg and animate the stroke-dasharray attribute with JS :
var count = $(('#count'));
$({ Counter: 0 }).animate({ Counter: count.text() }, {
duration: 5000,
easing: 'linear',
step: function () {
count.text(Math.ceil(this.Counter)+ "%");
}
});
var s = Snap('#animated');
var progress = s.select('#progress');
progress.attr({strokeDasharray: '0, 251.2'});
Snap.animate(0,251.2, function( value ) {
progress.attr({ 'stroke-dasharray':value+',251.2'});
}, 5000);
body{text-align:center;font-family:sans-serif;}

Answer 2

Pure HTML/CSS Solution
In short, I used the CSS border-radius and z-index properties to create a white half circle layered beneath an orange center circle and orange outer ring. Initially, the half-circle is completely hidden behind an additional layer of orange on the left side, but its outer edge is gradually revealed as it rotates around the center axis (via CSS transform: rotate()), creating the appearance of a progress bar. Additional trickery is required once the progress bar passes the halfway point (see below the snippet for more info).
All of this was done with pure HTML and CSS, except the animation, which uses JavaScript. It may appear to require more code than the SVG-based solutions, but the markup is actually much simpler, which makes it a good alternative in my opinion.
function setProgress(elem, percent) {
var
degrees = percent * 3.6,
transform = /MSIE 9/.test(navigator.userAgent) ? 'msTransform' : 'transform';
elem.querySelector('.counter').setAttribute('data-percent', Math.round(percent));
elem.querySelector('.progressEnd').style[transform] = 'rotate(' + degrees + 'deg)';
elem.querySelector('.progress').style[transform] = 'rotate(' + degrees + 'deg)';
if(percent >= 50 && !/(^|\s)fiftyPlus(\s|$)/.test(elem.className))
elem.className += ' fiftyPlus';
}
(function() {
var
elem = document.querySelector('.circlePercent'),
percent = 0;
(function animate() {
setProgress(elem, (percent += .25));
if(percent < 100)
setTimeout(animate, 15);
})();
})();
.circlePercent {
position: relative;
top: 26px;
left: 26px;
width: 96px;
height: 96px;
border-radius: 50%;
background: orange;
}
.circlePercent:before,
.circlePercent > .progressEnd {
position: absolute;
z-index: 3;
top: 2px;
left: 45px;
width: 6px;
height: 6px;
border-radius: 50%;
background: white;
-ms-transform-origin: 3px 46px;
transform-origin: 3px 46px;
content: "";
}
.circlePercent:after,
.circlePercent > .progress {
position: absolute;
-ms-transform-origin: 48px 48px;
transform-origin: 48px 48px;
z-index: 0;
top: 0;
left: 0;
width: 48px;
height: 96px;
border-radius: 48px 0 0 48px;
background: orange;
content: "";
}
.circlePercent.fiftyPlus:after {
background: white;
-ms-transform: rotate(180deg);
transform: rotate(180deg);
}
.circlePercent > .progress.progress {
background: white;
}
.circlePercent > .counter {
position: absolute;
box-sizing: border-box;
z-index: 2;
width: 100px;
height: 100px;
margin-top: -2px;
margin-left: -2px;
border-radius: 50%;
border: 4px solid orange;
}
.circlePercent > .counter:before {
position: absolute;
z-index: 1;
top: 50%;
margin-top: -13px;
width: 100%;
height: 26px;
font-size: 26px;
line-height: 26px;
font-family: sans-serif;
text-align: center;
color: white;
content: attr(data-percent) "%";
}
.circlePercent > .counter:after {
position: absolute;
width: 80px;
height: 80px;
top: 6px;
left: 6px;
border-radius: 50%;
background: orange;
content: "";
}
.circlePercent > .counter[data-percent="100"] {
background: white;
}
<div class="circlePercent">
<div class="counter" data-percent="0"></div>
<div class="progress"></div>
<div class="progressEnd"></div>
</div>
Notice that the fiftyPlus class is added to the container element once the progress bar reaches the halfway point. This adds a static progress bar to the right half of the circle. Without it, the progress will appear to drain out of the right side instead of filling in the left side.

Demo : CODEPEN
Here is my attempt at getting the percentage circle indicator:
Path draws two arches and i set the stroke-dasharray.
we don't really need to set the dasharray since we set that later with javascript.
Html
<svg class="circles" viewbox="0 0 200 200">
<g id="first">
<circle r="50" cx="100" cy="100" fill="#fb0"/>
<path fill="none"
stroke-linecap="round"
stroke-width="7"
stroke="#ffa"
stroke-dasharray="250,250"
d="M100 60
A1 1 0 0 1 100 140
A1 1 0 0 1 100 60"/>
<text class="circ-text"
text-anchor="middle"
x="100" y="100"
font-size="12px"
fill="#ffa"
>percentage
</text>
</g>
</svg>
Javascirpt
Get the path with #first path.
Get the length of the dash-array: path.getTotalLength();
Increase the dash-array until its full: setAttribute('stroke-dasharray', i+","+length); Where i is increased.
Find out what percentage we are at: (count++/ticks)*100
add the percentage to the svg text: text.innerHTML=(count/tick)*100
var path = document.querySelector('#first path');
var text = document.querySelector('#first .circ-text');
var length = path.getTotalLength();
var i = 0;
var count = 0;
var ticks = 50;
setInterval(function() {
if (i < length+length/ticks) {
path.setAttribute('stroke-dasharray', i+","+length);
i+=length/ticks;
text.innerHTML=Math.round((count++/ticks)*100);
}
}, 100);
var path = document.querySelector('#first path');
var text = document.querySelector('#first .circ-text');
var length = path.getTotalLength();
var i = 0;
var count = 0;
var ticks = 50;
setInterval(function() {
if (i < length+length/ticks) {
path.setAttribute('stroke-dasharray', i+","+length);
i+=length/ticks;
text.innerHTML=Math.round((count++/ticks)*100);
}
}, 100);
<svg class="circles" viewbox="0 0 500 200">
<g id="first">
<circle r="50" cx="100" cy="100" fill="#fb0" />
<path fill="none" stroke-linecap="round" stroke-width="7" stroke="#ffa" stroke-dasharray="250,250" d="M100 60 A1 1 0 0 1 100 140
A1 1 0 0 1 100 60" />
<text class="circ-text" text-anchor="middle" x="100" y="100" font-size="12px" fill="#ffa">percentage</text>
</g>

Circular Percent Progress bar using Canvas ...
var ctx = document.getElementById('circularLoader').getContext('2d');
var al = 0;
var start = 4.72;
var cw = ctx.canvas.width;
var ch = ctx.canvas.height;
var diff;
function progressSim(){
diff = ((al / 100) * Math.PI*2*10).toFixed(2);
ctx.clearRect(0, 0, cw, ch);
ctx.lineWidth = 17;
ctx.fillStyle = '#4285f4';
ctx.strokeStyle = "#4285f4";
ctx.textAlign = "center";
ctx.font="28px monospace";
ctx.fillText(al+'%', cw*.52, ch*.5+5, cw+12);
ctx.beginPath();
ctx.arc(100, 100, 75, start, diff/10+start, false);
ctx.stroke();
if(al >= 100){
clearTimeout(sim);
// Add scripting here that will run when progress completes
}
al++;
}
var sim = setInterval(progressSim, 50);
<div id="loader">
<canvas id="circularLoader" width="200" height="200"></canvas>
</div>
