Comment créer un menu qui ressemble à ceci ...

Lien vers PSD

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

Une version du menu qui utilise le PSD pour générer des images de l'info-bulle et ensuite l'utiliser peut être trouvée ici .

Près de 3 ans plus tard, j'ai finalement pris le temps de revoir cela et de publier une version améliorée. Vous pouvez toujours voir la réponse d'origine à la fin pour référence.

Alors que SVG peut être le meilleur choix, surtout aujourd'hui, mon objectif était de garder juste HTML et CSS, pas de JS, pas de SVG, pas d'images (autres que l'arrière-plan de l'élément racine).

Le HTML est assez simple. J'utilise la case à cocher pirater pour révéler / 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 garder cette logique et faciliter le changement 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 {
    transform: scale(1); 
    opacity: .999;
    // ease out back from easings.net/#easeOutBack
    transition: .5s cubic-bezier(0.175, 0.885, 0.32, 1.275);

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

Ma solution n'est peut-être pas tout à fait 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 SVG pour celui-ci, saisi la définition de chemin pour l'arc à partir du fichier SVG exporté et utilisé Raphael pour créer mon interface avec.

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

Un avantage de cette méthode est que vous pouvez utiliser n'importe quel nombre d'éléments et qu'elle continuera à les positionner radialement, sans avoir à changer aucun de vos 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');
}
