Cercle de progression CSS

J’ai créé un tutoriel sur comment faire exactement cela avec CSS3 et la bibliothèque JavaScript LESS. Vous pouvez trouver le blogpost ici: https://medium.com/secoya-tech/a917b80c43f9

Voici un jsFiddle du résultat final. Le pourcentage est défini via l’atsortingbut data-progress . Les modifications sont animées à l’aide de transitions CSS.

J’ai créé un violon en utilisant uniquement le css .

HTML

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 atsortingbutes 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 */ }

Ou cette belle barre de progression ronde avec HTML5, CSS3 et JavaScript.

Que dire de cela?

HTML

Javascript

 var el = document.getElementById('graph'); // get canvas var options = { percent: el.getAtsortingbute('data-percent') || 25, size: el.getAtsortingbute('data-size') || 220, lineWidth: el.getAtsortingbute('data-line') || 15, rotate: el.getAtsortingbute('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; } 

http://jsfiddle.net/Aapn8/3410/

Le code de base a été extrait du graphique PIE simple http://rendro.github.io/easy-pie-chart/

Une autre solution à base de css pure basée sur deux éléments arrondis découpés que je tourne 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 pivoter selon les besoins.

assez facile à comprendre

J’espère que ça aide, Maayan
