Webiopi多按钮css

Question

我想用不同的颜色改变按钮的背景颜色，但最终在按钮和.bd中出现了重叠的css

Javascript：

var restart = webiopi().createMacroButton("macro", "restart", "myMacroWithoutArgs1");
            $("#restart").append(restart);
            var shutdown = webiopi().createMacroButton("macro", "shutdown", "myMacroWithoutArgs2");
            $("#shutdown").append(shutdown);
            var schedule_set = webiopi().createMacroButton("debug", "debug");
            $("#debug").append(schedule_set);
            var back = webiopi().createMacroButton("back", "หน้าหลัก");
            $("#back").append(back);

CSS：

    <style type="text/css">
             button {
                    display: block;
                    margin: 5px 5px 5px 5px;
                    width: 160px;
                    height: 45px;
                    font-size: 24pt;
                    font-weight: bold;
                    color: white;
            }
            .bd{
            display: block;
                    margin: 5px 5px 5px 5px;
                    width: 160px;
            height: 45px;
            font-size: 24pt;
            font-weight: bold;
            box-shadow: 3px 4px 0px 0px #1564ad;
            background:-webkit-gradient(linear, left top, left bottom, color-stop(0.05, #79bbff), color-stop(1, #378de5));
            background:-moz-linear-gradient(top, #79bbff 5%, #378de5 100%);
            background:-webkit-linear-gradient(top, #79bbff 5%, #378de5 100%);
            background:-o-linear-gradient(top, #79bbff 5%, #378de5 100%);
            background:-ms-linear-gradient(top, #79bbff 5%, #378de5 100%);
            background:linear-gradient(to bottom, #79bbff 5%, #378de5 100%);
            background-color:#666666;
            }
    </style>

HTML：

<div id="debug"
onClick="self.location='debug.html'">
</div>
<div id="restart"></div>
<div class="bd" id="shutdown"></div>
<div id="back"
onClick="self.location='index.html'">
</div>

希望有人能告诉我如何正确解决这个问题？谢谢

请看这篇文章，里面有你正在寻找的代码，http://www.coderewind.com/2015/10/build-a-raspberry-pi-wifi-rc-car/，我在一个div上堆叠了控件。
