使用CSS和HTML5使用梯形创建导航按钮

旧版本如下,它使用jQuery调整大小.但在查看这个问题后:SVG多边形点支持百分比单位,你可以通过应用百分比并且不需要任何JS来实现相同的效果:

看到它在这里工作:http://jsfiddle.net/th4uo8wk/4/

老答案:

哎呀,当我准备好的时候,Paulie_D得到了答案.

好吧,在这里你有一个响应的(你可以看到它在这个jsfiddle工作,调整屏幕大小,看它响应工作):

HTML:

JS/JQUERY

function resizeButtons() {
    // get the width
    var w = $("#mySVG").width();

    // make it squared
    $("#mySVG").height(w);

    // recalculate the position of each polygon
    $("#ok").attr("points", w * 0.25 + "," + w * 0.25 + " " + w * 0.75 + "," + w * 0.25 + " " + w * 0.75 + "," + w * 0.75 + " " + w * 0.25 + "," + w * 0.75);
    $("#up").attr("points", "0,0 " + w + ",0 " + w * 0.75 + "," + w * 0.25 + " " + w * 0.25 + "," + w * 0.25);
    $("#left").attr("points", w + ",0 " + w + "," + w + " " + w * 0.75 + "," + w * 0.75 + " " + w * 0.75 + "," + w * 0.25);
    $("#down").attr("points", "0," + w + " " + w * 0.25 + "," + w * 0.75 + " " + w * 0.75 + "," + w * 0.75 + " " + w + "," + w);
    $("#right").attr("points", "0,0 " + w * 0.25 + "," + w * 0.25 + " " + w * 0.25 + "," + w * 0.75 + " 0," + w);
}

CSS

svg { background:#ccc; }
#ok { fill: red; }
#up { fill: blue; }
#down { fill: green; }
#right { fill: yellow; }
#left { fill: orange; }

正如其他人已经指出的那样,你应该使用SVG.以下是您可以使用的CSS替代方案.

它使用转换的伪元素和transform-origin属性.要使其响应,您需要更改单位.由于这种方法中的单位是em,只需更改父元素或body元素中的字体大小即可.
