Creando un Menú Radial en CSS

Question

¿Cómo creo un menú que se parece a esto ...

Enlace a PSD

No quiero usar las imágenes PSD. Preferiría usar íconos de algún paquete como FontAwesome y tener los fondos / css generados en CSS.

here puede encontrar una versión del menú que utiliza la PSD para generar imágenes de la información sobre herramientas y luego usarla.

Answer 1

La respuesta de Ana es patear traseros! Eso es algo serio de CSS-fu.

Puede que mi solución no sea exactamente lo que está esperando, pero es otra solución posible. Estoy trabajando en una interfaz de brújula en este momento que tiene un estilo similar de botones en forma de arco. Decidí desarrollarlo usando Raphael y SVG.

Creé una forma de arco en Illustrator, exporté el SVG para él, tomé la definición de la ruta del arco del archivo SVG exportado y usé Raphael para construir mi interfaz con él.

Aquí hay un JSFiddle de ello .

Aquí está el 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);
}

Aquí está el CSS relacionado:

#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;
}

Answer 2

Otra muy buena forma sería usar JavaScript para el posicionamiento.

DEMO + TUTORIAL sobre cómo hacer un menú radial animado

Un profesional de este método es que puedes usar cualquier número de elementos y los mantendrá posicionados radialmente, sin tener que cambiar ninguno de tus CSS.

El JavaScript en cuestión es:

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'');
}

Answer 3

Casi 3 años después, finalmente hice el tiempo para revisar esto y publicar una versión mejorada. Todavía puede ver la respuesta original al final para referencia.

Si bien SVG puede ser la mejor opción, especialmente hoy, mi objetivo con esto era mantenerlo solo en HTML y CSS, sin JS, sin SVG, sin imágenes (aparte del fondo del elemento raíz).

Código

El HTML es bastante simple. Estoy usando la casilla de verificación hackear para mostrar / ocultar el menú.

<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>

Estoy usando Sass para mantener esto lógico y facilitar el cambio de las cosas si es necesario. Muy comentado.
