Créer un menu radial en CSS

Comment créer un menu qui ressemble à ceci ...

Tooltip Image

Lien vers PSD

Je ne veux pas utiliser les images PSD. Je préférerais utiliser les icônes de certains packages tels que FontAwesome et avoir les arrière-plans/css générés en CSS.

Vous pouvez trouver une version du menu qui utilise le PSD pour générer des images de l’info-bulle puis l’utiliser ici .

Près de 3 ans plus tard, j'ai finalement pris le temps de revenir sur ce sujet et de publier une version améliorée. Vous pouvez toujours voir la réponse originale à la fin pour référence.

Alors que SVG peut être le meilleur choix, en particulier aujourd'hui, mon objectif était de ne conserver que le HTML et le CSS, pas de JS, pas de SVG, pas d'images (autre que l'arrière-plan de l'élément racine).

Code

Le HTML est assez simple. J'utilise la case à cocher pour afficher/masquer le menu.

<input type='checkbox' id='t'/>
<label for='t'>✰</label>
<ul>
    <li><a href='#'>☀</a></li>
    <li><a href='#'>☃</a></li>
    <li><a href='#'>☁</a></li>
</ul>

J'utilise Sass pour maintenir cette logique et faciliter les modifications si nécessaire. Fortement commenté.

$d: 2em; // diameter of central round button
$r: 16em; // radius of menu
$n: 3; // must match number of list items in DOM
$exp: 3em; // menu item height
$tip: .75em; // dimension of tip on middle menu item
$w: .5em; // width of ends
$cover-dim: 2*($r - $exp); // dimension of the link cover
$angle: 15deg; // angle for a menu item
$skew-angle: 90deg - $angle; // how much to skew a menu item to $angle
$scale-factor: cos($skew-angle); // correction factor - see vimeo.com/98137613 from min 15
$off-angle: .125deg; // offset angle so we have a little space between menu items

// don't show the actual checkbox
input {
  transform: translate(-100vw); // move offscreen
  visibility: hidden; // avoid Paint
}

// change state of menu to revealed on checking the checkbox
input:checked ~ ul {

La réponse d'Ana est un coup de pied! C'est du sérieux CSS-fu.

Ma solution ne correspond peut-être pas à ce que vous espérez, mais c'est une autre solution possible. Je travaille actuellement sur une interface de boussole qui a un style similaire de boutons en forme d'arc. J'ai décidé de le développer en utilisant Raphael et SVG.

J'ai créé une forme d'arc dans Illustrator, exporté le fichier SVG correspondant, saisi la définition du chemin d'accès pour l'arc à partir du fichier SVG exporté et utilisé Raphael pour créer mon interface avec celui-ci.

en voici un JSFiddle .

Voici le JavaScript:

var arc = {
    fill: '#333',
    stroke: '#333',
    path: 'M53.286,44.333L69.081,7.904C48.084-1.199,23.615-2.294,0.648,6.78l14.59,36.928C28.008,38.662,41.612,39.27,53.286,44.333z'
};

var paper = Raphael(document.getElementById("notepad"), 500, 500);

var arcDegrees = 45;
var centerX = 210;
var centerY = 210;
var compassRadius = 68;
var currentlyActive = 45;
var directions = [
    {label:'N', degrees:0, rotatedDegrees:270}, 
    {label:'NE', degrees:45, rotatedDegrees:315}, 
    {label:'E', degrees:90, rotatedDegrees:0}, 
    {label:'SE', degrees:135, rotatedDegrees:45}, 
    {label:'S', degrees:180, rotatedDegrees:90}, 
    {label:'SW', degrees:225, rotatedDegrees:135}, 
    {label:'W', degrees:270, rotatedDegrees:180}, 
    {label:'NW', degrees:315, rotatedDegrees:225}
];

function arcClicked()
{
    var label = $(this).data('direction-label');
    $("#activeArc").attr('id', null);
    $(this).attr('id', 'activeArc');
}

for (i = 0; i < 360; i += arcDegrees) {
    var direction = _.find(directions, function(d) { return d.rotatedDegrees == i; });
    var radians = i * (Math.PI / 180);
    var x = centerX + Math.cos(radians) * compassRadius;
    var y = centerY + Math.sin(radians) * compassRadius;

    var newArc = paper.path(arc.path);
    // newArc.translate(x, y);
    // newArc.rotate(i + 89);
    newArc.transform('T' + x + ',' + y + 'r' + (i + 89));

    if (direction.degrees == currentlyActive) {
        $(newArc.node).attr('id', 'activeArc');
    }

    $(newArc.node)
        .attr('class', 'arc')
        .data('direction-label', direction.label)
        .on('click', arcClicked);
}

Voici le CSS associé:

#notepad {
    background: #f7f7f7;
    width: 500px;
    height: 500px;
}

.arc {
    fill: #999;
    stroke: #888;
    cursor: pointer;
}

.arc:hover {
    fill: #777;
    stroke: #666;
}

#activeArc {
    fill: #F18B21 !important;
    stroke: #b86a19 !important;
}

Un autre très bon moyen serait d'utiliser JavaScript pour le positionnement.

DEMO + TUTORIAL sur la création d'un menu radial animé

L’un des avantages de cette méthode est que vous pouvez utiliser n’importe quel nombre d’éléments et il continuera à les positionner de manière radiale, sans avoir à changer votre code CSS.

Le JavaScript en question est:

var items = document.querySelectorAll('.circle a');

for(var i = 0, l = items.length; i < l; i++) {
  items[i].style.left = (50 - 35*Math.cos(-0.5 * Math.PI - 2*(1/l)*i*Math.PI)).toFixed(4) + "%";

  items[i].style.top = (50 + 35*Math.sin(-0.5 * Math.PI - 2*(1/l)*i*Math.PI)).toFixed(4) + "%";
}

document.querySelector('.menu-button').onclick = function(e) {
   e.preventDefault(); document.querySelector('.circle').classList.toggle('open');
}
