このようなメニューを作成するにはどうすればいいですか...
PSD画像は使いたくありません。私は FontAwesome のようないくつかのパッケージからのアイコンを使うことを好み、CSSでbackground/cssを生成します。
PSDを使用してツールチップのイメージを生成してから使用しているメニューのバージョンは、 こちら にあります。
ほぼ3年後、私はついにこれを再検討して改良版を投稿する時間を作りました。参考のために最後に元の回答を表示することもできます
SVGは特に良い選択かもしれませんが、今日の私の目標は、HTMLとCSS、JS、SVG、画像(ルート要素の背景以外)を保持することでした。

HTMLはとても単純です。チェックボックスハックを使ってメニューを表示/非表示にしています。

私はSassを使用してこれを論理的に保ち、必要に応じて変更しやすくしています。大いにコメントした。

アナの反応は尻キックです!それは深刻なCSS-fuです。
私の解決策はあなたが望んでいるものとは全く違うかもしれませんが、それは別の可能な解決策です。私は今、コンパスインターフェースを開発中です。 Raphael とSVGを使って開発することにしました。
Illustratorで円弧形状を作成し、それにSVGをエクスポートし、エクスポートされたSVGファイルから円弧のパス定義を取得し、それを使ってインターフェイスを作成しました。
これがJavaScriptです。
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);
}
これが関連CSSです。
#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;
}
もう1つの非常に良い方法は、ポジショニングにJavaScriptを使用することです。
デモ+ラジアルメニューのアニメーション作成に関するチュートリアル
この方法の長所は、要素をいくつでも使用でき、CSSを変更しなくても要素を放射状に配置し続けることです。
問題のJavaScriptは次のとおりです。
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');
}
