Cercle de progression CSS

Question

J'ai cherché sur ce site des barres de progression, mais celles que j'ai pu trouver montrent des cercles animés qui vont jusqu'à 100%.

Je voudrais qu'il s'arrête à certains pourcentages comme dans la capture d'écran ci-dessous. Y a-t-il un moyen de faire cela en utilisant uniquement les CSS ?

Answer 1

J'ai créé un tutoriel sur la façon de faire exactement cela avec CSS3 exclusivement (pas de JS requis). Vous pouvez trouver le billet de blog ici : https://medium.com/secoya-tech/a917b80c43f9

Voici un jsFiddle du résultat final. Le pourcentage est défini via la fonction data-progress attribut. Les changements sont animés à l'aide de transitions CSS.

Answer 2

J'ai créé un violon en utilisant uniquement CSS .

.wrapper {
  width: 100px; /* Set the size of the progress bar */
  height: 100px;
  position: absolute; /* Enable clipping */
  clip: rect(0px, 100px, 100px, 50px); /* Hide half of the progress bar */
}
/* Set the sizes of the elements that make up the progress bar */
.circle {
  width: 80px;
  height: 80px;
  border: 10px solid green;
  border-radius: 50px;
  position: absolute;
  clip: rect(0px, 50px, 100px, 0px);
}
/* Using the data attributes for the animation selectors. */
/* Base settings for all animated elements */
div[data-anim~=base] {
  -webkit-animation-iteration-count: 1;  /* Only run once */
  -webkit-animation-fill-mode: forwards; /* Hold the last keyframe */
  -webkit-animation-timing-function:linear; /* Linear animation */
}

.wrapper[data-anim~=wrapper] {
  -webkit-animation-duration: 0.01s; /* Complete keyframes asap */
  -webkit-animation-delay: 3s; /* Wait half of the animation */
  -webkit-animation-name: close-wrapper; /* Keyframes name */
}

.circle[data-anim~=left] {
  -webkit-animation-duration: 6s; /* Full animation time */
  -webkit-animation-name: left-spin;
}

.circle[data-anim~=right] {
  -webkit-animation-duration: 3s; /* Half animation time */
  -webkit-animation-name: right-spin;
}
/* Rotate the right side of the progress bar from 0 to 180 degrees */
@-webkit-keyframes right-spin {
  from {
    -webkit-transform: rotate(0deg);
  }
  to {
    -webkit-transform: rotate(180deg);
  }
}
/* Rotate the left side of the progress bar from 0 to 360 degrees */
@-webkit-keyframes left-spin {
  from {
    -webkit-transform: rotate(0deg);
  }
  to {
    -webkit-transform: rotate(360deg);
  }
}
/* Set the wrapper clip to auto, effectively removing the clip */
@-webkit-keyframes close-wrapper {
  to {
    clip: rect(auto, auto, auto, auto);
  }
}

<div class="wrapper" data-anim="base wrapper">
  <div class="circle" data-anim="base left"></div>
  <div class="circle" data-anim="base right"></div>
</div>

Answer 3

Qu'en est-il ?

HTML

<div class="chart" id="graph" data-percent="88"></div>

Javascript

var el = document.getElementById('graph'); // get canvas

var options = {
    percent:  el.getAttribute('data-percent') || 25,
    size: el.getAttribute('data-size') || 220,
    lineWidth: el.getAttribute('data-line') || 15,
    rotate: el.getAttribute('data-rotate') || 0
}

var canvas = document.createElement('canvas');
var span = document.createElement('span');
span.textContent = options.percent + '%';

if (typeof(G_vmlCanvasManager) !== 'undefined') {
    G_vmlCanvasManager.initElement(canvas);
}

var ctx = canvas.getContext('2d');
canvas.width = canvas.height = options.size;

el.appendChild(span);
el.appendChild(canvas);

ctx.translate(options.size / 2, options.size / 2); // change center
ctx.rotate((-1 / 2 + options.rotate / 180) * Math.PI); // rotate -90 deg

//imd = ctx.getImageData(0, 0, 240, 240);
var radius = (options.size - options.lineWidth) / 2;

var drawCircle = function(color, lineWidth, percent) {
        percent = Math.min(Math.max(0, percent || 1), 1);
        ctx.beginPath();
        ctx.arc(0, 0, radius, 0, Math.PI * 2 * percent, false);
        ctx.strokeStyle = color;
        ctx.lineCap = 'round'; // butt, round or square
        ctx.lineWidth = lineWidth
        ctx.stroke();
};

drawCircle('#efefef', options.lineWidth, 100 / 100);
drawCircle('#555555', options.lineWidth, options.percent / 100);

et CSS

div {
    position:relative;
    margin:80px;
    width:220px; height:220px;
}
canvas {
    display: block;
    position:absolute;
    top:0;
    left:0;
}
span {
    color:#555;
    display:block;
    line-height:220px;
    text-align:center;
    width:220px;
    font-family:sans-serif;
    font-size:40px;
    font-weight:100;
    margin-left:5px;
}

Le code de base est tiré du tableau Simple PIE http://rendro.github.io/easy-pie-chart/

Answer 4

Une autre solution purement css qui est basée sur deux éléments arrondis découpés que je fais pivoter pour obtenir le bon angle :

http://jsfiddle.net/maayan/byT76/

C'est le css de base qui le permet :

.clip1 {
    position:absolute;
    top:0;left:0;
    width:200px;
    height:200px;
    clip:rect(0px,200px,200px,100px);
}
.slice1 {
    position:absolute;
    width:200px;
    height:200px;
    clip:rect(0px,100px,200px,0px);
    -moz-border-radius:100px;
    -webkit-border-radius:100px; 
    border-radius:100px;
    background-color:#f7e5e1;
    border-color:#f7e5e1;
    -moz-transform:rotate(0);
    -webkit-transform:rotate(0);
    -o-transform:rotate(0);
    transform:rotate(0);
}

.clip2 
{
    position:absolute;
    top:0;left:0;
    width:200px;
    height:200px;
    clip:rect(0,100px,200px,0px);
}

.slice2
{
    position:absolute;
    width:200px;
    height:200px;
    clip:rect(0px,200px,200px,100px);
    -moz-border-radius:100px;
    -webkit-border-radius:100px; 
    border-radius:100px;
    background-color:#f7e5e1;
    border-color:#f7e5e1;
    -moz-transform:rotate(0);
    -webkit-transform:rotate(0);
    -o-transform:rotate(0);
    transform:rotate(0);
}

et le js le fait tourner selon les besoins.

assez facile à comprendre

J'espère que cela vous aidera, Maayan
