在CSS中创build一个径向菜单

如何创build一个看起来像这样的菜单…

工具提示图像

链接到PSD

我不想使用PSD图像。 我宁愿使用像FontAwesome这样的软件包中的图标,并在CSS中生成背景/ css。

使用PSD来生成工具提示的图像然后使用它的菜单的版本可以在这里find。

差不多3年后,我终于有时间重新审视这个问题,并发表一个改进版。 您仍然可以在最后查看原始答案以供参考。

虽然SVG可能是更好的select,特别是今天,我的目标是保持它只是HTML和CSS,没有JS,没有SVG,没有图像(根元素背景除外)。

HTML非常简单。 我使用checkboxhack来显示/隐藏菜单。

<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> 

我使用Sass来保持这个逻辑,并且如果需要,可以更容易地进行更改。 沉重的评论。

安娜的回应是踢屁股! 这是一些严重的CSS-fu。

我的解决scheme可能并不完全是你所希望的,但这是另一种可能的解决scheme。 我现在正在制作一个指南针界面,它具有类似弧形button的样式。 我决定用Raphael和SVG来开发它。

我在Illustrator中创build了一个弧形,为它导出了SVG,从导出的SVG文件中抓取了弧的path定义,并使用Raphael来构build我的界面。

这是一个JSFiddle 。

这里是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); } 

这里是相关的CSS:

 #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; } 

另一个非常好的方法是使用JavaScript进行定位。

DEMO + TUTORIAL制作animation放射状菜单

一个赞成这种方法是,你可以使用任何数量的元素,并将保持径向放置,而不必改变你的任何CSS。

有问题的JavaScript是:

 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'); }
