Google+的“button”效果一直都吸引了我，早就想亲手去体会一下这样的感觉，但一直给自己找借口，直到最近几天，终于动手一试了，试后才知道，他们做的真NB。Google+的UI Buttons形成了一个制作“按钮”、“图标按钮”、“带有标签的图标按钮”、“下拉按钮”、“tip按钮”等按钮的工具或者说UI Buttons框架，使用这一套“UI Button”将会给你的工作带来极大的速度与视觉冲击效果。

那么我们今天的目的就是来看看Google+的攻城师是怎么写的这个代码。因为只有通过代码，我们才能知道其中的原理与制作过程。

HTML Markup:

老样子，首先就需要他的HTML Markup是怎么写的，因为我们在实际应用中这一块是不可缺少的，如果没有这一块，你就无法继续下去，俗话说得好“巧妇难为无米之炊”。下面我们不说别的，直接上代码才是王道：

			<a href="#" class="button"><span class="label">Button</span></a>
			<button><span class="label">Button</span></button>
		

上面的代码是用于单个按钮的，不过我们有时需要几个代码在同一行，类似于菜单的效果，那么最好在外面加上一个包裹容器：

			<div class="buttons">
			  <a class="button" href="#"><span class="label">button</span></a>
			  <a class="button" href="#"><span class="label">button</span></a>
			</div>
		

这样写的好处是：“对于单个Button并看不出其好处，但对于多个处于同一行的Button效果来说，加上这个“div.buttons”容器就很有必要了。我们可以在这个元素上进行浮动的清除，当然你也可以在这个元素上加上一个“clearfix”类名”。

			.buttons {
					/* Style as you wish (toolbar)*/
			 }
			 .buttons:before,
			 .buttons:after {
					content:"";
					display: table;
			 }
			 .buttons:after {
					clear: both;
			 }
			 .buttons {
					zoom:1;
			 }
		

上面我采用的是直接在“.buttons”上清除浮动，没有增加任何标签或者属性值。有关于清除浮动的方法有多种，如果您想了解这方面的知识点，不仿点击《Clear Float》进去看看。

那么说了这么多，我个人强烈建议“不管是单个按钮或者多个按钮，最好都给“button”加上这个“div.buttons”容器”。

			<div class="buttons"><a href="#" class="button"><span class="label">Button</span></a></div>
		

或者：

			<div class="buttons">
			  <a href="#" class="button left"><span class="label">Left Button</span></a>
			  <a href="#" class="button middle"><span class="label">Middle Button</span></a>
			  <a href="#" class="button right"><span class="label">Right Button</span></a>
			</div>
		

上面的结构是我们制作“基本按钮”的一个HTML Markup，但对于后面的“下接按钮”和“TIP按钮”，我们到时还是需要做出一定的修改，详细的可以留意后面的变化，在没有进行另外的说明，都将是以这种“HTML Markup”来制作“Button”。

前面主要介绍了制作“Button”的“HTML Markup”，下面主要来其样式。样式我主要以这样的方式来给大家呈现：首先是“HTML Markup”，接着是“CSS Code”，最后在给大家一个对应的效果图。首先将“Google+的UI Button”分成以下几类：

1. 基本按钮
2. ON Button
3. 动作按钮
4. 颜色按钮
5. Inline Button
6. Negative and postion Buttons
7. 图标按钮
8. Tip按钮
9. 有标签的图标按钮
10. 下接菜单按钮

一、基本按钮

HTML Markup

			<div class="buttons">
			  <button>
			    <span class="label">Button</span>
			  </button>
			</div>
			<!-- ======OR======== -->
			<div class="buttons">
			  <a class="button">
			    <span class="label">Button</span>
			  </a>
			</div>
		

CSS Code

			/*Default style*/
			button,
			.button {
				text-decoration: none;
				text-shadow: 0 1px 0 #fff;
				
				font: bold 11px Helvetica, Arial, sans-serif;
				color: #444;
				line-height: 17px;
				height: 18px;
				
				display: inline-block;
				float: left;
				
				margin: 5px;
				padding: 5px 6px 4px 6px;
				
				background: #F3F3F3;
				border: solid 1px #D9D9D9;
				
				-webkit-border-radius: 2px;
				-moz-border-radius: 2px;
				border-radius: 2px;
				
				-webkit-transition: border-color .20s;
				-moz-transition: border-color .20s;
				-o-transition: border-color .20s;
				transition: border-color .20s;
			}
			button {
				height: 29px !important;
				cursor: pointer;
			}
			/*Suspended state style (:hover)*/
			button:hover,
			.button:hover {
				background: #F4F4F4;
				border-color: #C0C0C0;
				color: #333;
				text-decoration: none;
			}	

			/*Click on the state effect(:active)*/
			button:active, 
			.button:active {
				border-color: #4D90FE;
				color: #4D90FE;
				
				-moz-box-shadow:inset 0 0 10px #D4D4D4;
				-webkit-box-shadow:inset 0 0 10px #D4D4D4;
				box-shadow:inset 0 0 10px #D4D4D4;
			}
			/*label style*/
			.ddm span.label, 
			button span.label, 
			.button span.label {
				display: inline-block;
				float: left;
				line-height: 17px;
				height: 18px;
				padding: 0 1px;
				overflow: hidden;
				color: #444;
				
				-webkit-transition: color .20s;
				-moz-transition: color .20s;
				-o-transition: color .20s;
				transition: color .20s;
			} 
			button span.label {
				line-height: 15px !important;
			}
			.ddm:active span.label, 
			button:active span.label, 
			.button:active span.label {
					color: #4D90FE;
			}

			button:hover .label, 
			.button:hover .label {
					color: #333;
			}

			button:hover .label.red, 
			.button:hover .label.red {
					color: #DB4A37;
			}
			button:hover .label.blue, 
			.button:hover .label.blue {
					color: #7090C8;
			}
			button:hover .label.green, 
			.button:hover .label.green {
					color: #42B449;
			}
			button:hover .label.yellow, 
			.button:hover .label.yellow {
					color: #F7CB38;
			}

			button.blue .label, 
			.button.blue .label {
				color: #FFF !important;
				text-shadow: 0 1px 0 #2F5BB7 !important;
			}
			button.green .label, 
			.button.green .label {
				color: #FFF !important;
				text-shadow: 0 1px 0 #2D6200 !important;
			}
			button.red .label, 
			.button.red .label {
				color: #FFF !important;
				text-shadow: 0 1px 0 #B0281A !important;
			}
			button.action .label, 
			.button.action .label {
				padding: 0 17px !important;
			}

			button.action:active .label, 
			.button.action:active .label {
				color: #333 !important;
			}

			button.blue:active .label, 
			button.green:active .label, 
			button.red:active .label, 
			.button.blue:active .label, 
			.button.green:active .label, 
			.button.red:active .label {
				color: #FFF !important;
			}
		

效果

这个效果可以说是整个Google+的默认按钮效果。接下来我们一起来看第二种。

二、ON Button

这个效果只是在前面的默认按钮效果上做了一定的修改，这个修改也是很简单的，首先在“button”的HTML标签上增加一个“on”类名，然后样多在“.on”上增加一些别的样式效果，具体看代码吧：

HTML Markup

			<div class="buttons">
			  <button class="on">
			    <span class="label">On Button</span>
			  </button>
			</div>
			<!-- ====	OR  ==== -->
			<div class="buttons">
			  <a class="button on">
			    <span class="label">On Button</span>
			  </a>
			</div>
		

CSS Code

			button.on, 
			.button.on {
				border-color: #BBB;
				
				-moz-box-shadow:inset 0 0 10px #D4D4D4;
				-webkit-box-shadow:inset 0 0 10px #D4D4D4;
				box-shadow:inset 0 0 10px #D4D4D4;
			}
			button.on:hover, 
			.button.on:hover {
				border-color: #BBB;
				
				-moz-box-shadow:inset 0 0 10px #D4D4D4;
				-webkit-box-shadow:inset 0 0 10px #D4D4D4;
				box-shadow:inset 0 0 10px #D4D4D4;
			}
			button.on:active, 
			.button.on:active {
				border-color: #4D90FE;
			}
		

效果

三、动作按钮

动作按钮制作方法和“ON Button”是一样的，只需要在“button”上加上一个“.action”类名，其html代码和上面的“on button”是一样的，只不过把“on”换成了“action”。所以我们直接来看CSS代码的变化.

CSS Code

			button.action, 
			.button.action {
				border: 1px solid #D8D8D8 !important;
				
				background: #F2F2F2;
				background: -webkit-linear-gradient(top, #F5F5F5, #F1F1F1);
				background: -moz-linear-gradient(top, #F5F5F5, #F1F1F1);
				background: -ms-linear-gradient(top, #F5F5F5, #F1F1F1);
				background: -o-linear-gradient(top, #F5F5F5, #F1F1F1);
				
				-webkit-transition: border .20s;
				-moz-transition: border .20s;
				-o-transition: border .20s;
				transition: border .20s;
			}
			button.action:hover, 
			.button.action:hover {
				border: 1px solid #C6C6C6 !important;
				
				background: #F3F3F3;
				background: -webkit-linear-gradient(top, #F8F8F8, #F1F1F1);
				background: -moz-linear-gradient(top, #F8F8F8, #F1F1F1);
				background: -ms-linear-gradient(top, #F8F8F8, #F1F1F1);
				background: -o-linear-gradient(top, #F8F8F8, #F1F1F1);

				-moz-box-shadow: 0 1px 0px #DDD;
				-webkit-box-shadow: 0 1px 0px #DDD;
				box-shadow:iset 0 1px 0px #DDD;
			}
			button.action:active, 
			.button.action:active {
				-moz-box-shadow: none !important;
				-webkit-box-shadow: none !important;
				box-shadow: none !important;
				border-color: #C6C6C6 !important;
			}
		

效果

四、颜色按钮

这里只提供了几种颜色按钮的制作，当然大家可以按照这样的思路自己去配置更多的色彩颜色按钮库。其结构也没有多大的变化，只是在“.button”上增加一个“colorName”的类名，当然这个“colorName”是所指你需要的颜色的名称，他可以是“red,blue,green”等等。接下来只需改变相应的样式。

CSS Code

			/*Blue Button*/
			button.blue, 
			.button.blue {
				border: 1px solid #3079ED !important;
				
				background: #4B8DF8;
				background: -webkit-linear-gradient(top, #4C8FFD, #4787ED);
				background: -moz-linear-gradient(top, #4C8FFD, #4787ED);
				background: -ms-linear-gradient(top, #4C8FFD, #4787ED);
				background: -o-linear-gradient(top, #4C8FFD, #4787ED);
				
				-webkit-transition: border .20s;
				-moz-transition: border .20s;
				-o-transition: border .20s;
				transition: border .20s;
			}
			button.blue:hover, 
			.button.blue:hover {
				border: 1px solid #2F5BB7 !important;
				
				background: #3F83F1;
				background: -webkit-linear-gradient(top, #4D90FE, #357AE8);
				background: -moz-linear-gradient(top, #4D90FE, #357AE8);
				background: -ms-linear-gradient(top, #4D90FE, #357AE8);
				background: -o-linear-gradient(top, #4D90FE, #357AE8);
			}
			button.blue:active, 
			.button.blue:active {
				border-color: #2F5BB7 !important;
			}

			/*green button*/
			button.green, 
			.button.green {
				border: 1px solid #29691D !important;
				
				background: #3A8E00;
				background: -webkit-linear-gradient(top, #3C9300, #398A00);
				background: -moz-linear-gradient(top, #3C9300, #398A00);
				background: -ms-linear-gradient(top, #3C9300, #398A00);
				background: -o-linear-gradient(top, #3C9300, #398A00);
				
				-webkit-transition: border .20s;
				-moz-transition: border .20s;
				-o-transition: border .20s;
				transition: border .20s;
			}
			button.green:hover, 
			.button.green:hover {
				border: 1px solid #2D6200 !important;
				
				background: #3F83F1;
				background: -webkit-linear-gradient(top, #3C9300, #368200);
				background: -moz-linear-gradient(top, #3C9300, #368200);
				background: -ms-linear-gradient(top, #3C9300, #368200);
				background: -o-linear-gradient(top, #3C9300, #368200);
			}
			button.green:active, 
			.button.green:active {
				border-color: #2D6200 !important;
			}

			/*red button*/
			button.red, 
			.button.red {
				border: 1px solid #D14836 !important;
				
				background: #D64937;
				background: -webkit-linear-gradient(top, #DC4A38, #D14836);
				background: -moz-linear-gradient(top, #DC4A38, #D14836);
				background: -ms-linear-gradient(top, #DC4A38, #D14836);
				background: -o-linear-gradient(top, #DC4A38, #D14836);
				
				-webkit-transition: border .20s;
				-moz-transition: border .20s;
				-o-transition: border .20s;
				transition: border .20s;
			}
			button.red:hover, 
			.button.red:hover {
				border: 1px solid #B0281A !important;
				
				background: #D14130;
				background: -webkit-linear-gradient(top, #DC4A38, #C53727);
				background: -moz-linear-gradient(top, #DC4A38, #C53727);
				background: -ms-linear-gradient(top, #DC4A38, #C53727);
				background: -o-linear-gradient(top, #DC4A38, #C53727);
			}
			button.red:active, 
			.button.red:active {
				border-color: #B0281A !important;
			}
		

这里只写了几种颜色按钮的风格，大家要是对色彩有一定的了解，你可以按您自己想要的风格去写，另外这个色彩按钮一般都是配合“动作按钮”一起使用。只要在上面的样式基础上，改变一下HTML标签：

			<div class="buttons">
			  <a href="#" class="button red action"><span class="label">Upload</span></a>
			</div>
		

注：代码中的“red”类名就是所指的“colorName”，你可以根据需要换成你自己想的类名。当然写上相应的样式代码。

效果

五、Inline Button

这个效果是将“Buttons”以一行的风格显示，有点类似是横向菜单的效果。此处将其分为“left”、“middle”和“right”，需要注意的一点就是“left”和“right”将圆角效果去除一边，而“middle”的圆角效果全部清除。

HTML Markup

			<div class="buttons">
			  <a href="#" class="button left"><span class="label">Left</span></a>
			  <a href="#" class="button middle"><span class="label">Middle</span></a>
			  <a href="#" class="button right"><span class="label">right</span></a>
			</div>
		

CSS Code

			button.left, 
			.button.left {
				margin: 5px 0 5px 5px;
				
				border-top-right-radius: 0;
				-webkit-border-top-right-radius: 0;
				-moz-border-radius-topright: 0;
				
				border-bottom-right-radius: 0;
				-webkit-border-bottom-right-radius: 0;
				-moz-border-radius-bottomright: 0;
			}

			button.middle, 
			.button.middle {
				margin: 5px 0;
				
				border-left-color: #F4F4F4;
				
				border-radius: 0;
				-webkit-border-radius: 0;
				-moz-border-radius: 0;
			}
			button.right, 
			.button.right {
				margin: 5px 5px 5px 0;
				
				border-left-color: #F4F4F4;
				
				border-top-left-radius: 0;
				-webkit-border-top-left-radius: 0;
				-moz-border-radius-topleft: 0;
				
				border-bottom-left-radius: 0;
				-webkit-border-bottom-left-radius: 0;
				-moz-border-radius-bottomleft: 0;
			}
		

这段代码有一个细节问题，需要将上面的代码放置在“.button:hover”代码前面，因为我们此处没有为这几种按钮另写一个“:hover”效果。

效果

六、Negative and postion Buttons

第六种按钮效果和前面的“On Button”。“Action Button”类似，只是在“button”上增加了一个“negative”或者“position”类名，然后在单独为这两种类型按钮写了样式。

			.button.negative:hover {
				border: solid 1px #ff3333;
				text-shadow: 0 1px 0 #FCC;
				background: #ffcccc;
				background: -webkit-linear-gradient(top, #ff9999, #DD5555);
				background: -moz-linear-gradient(top, #ff9999, #DD5555);
				background: -ms-linear-gradient(top, #ff9999, #DD5555);
				background: -o-linear-gradient(top, #ff9999, #DD5555);
			}
			.button.positive:hover {
				border: solid 1px #009900;
				text-shadow: 0 1px 0 #CFC;
				background: #ccffcc;
				background: -webkit-linear-gradient(top, #99ff99, #559955);
				background: -moz-linear-gradient(top, #99ff99, #559955);
				background: -ms-linear-gradient(top, #99ff99, #559955);
				background: -o-linear-gradient(top, #99ff99, #559955);
			}
			.button.negative:active {
				border: solid 1px #FF3333;
				background: #ffaaaa;
				text-shadow: 0 1px 0 #CC7777;
				background: -webkit-gradient(linear, left top, left bottom, from(#BB3333), color-stop(0.15, #DD5555), to(#CC5555));
				background: -webkit-linear-gradient(top, #BB3333, #DD5555 15%, #CC5555);
				background: -moz-linear-gradient(top, #BB3333, #DD5555 15%, #CC5555);
				background: -ms-linear-gradient(top, #BB3333, #DD5555 15%, #CC5555);
				background: -o-linear-gradient(top, #BB3333, #DD5555 15%, #CC5555);
			}
			.button.positive:active {
				border: solid 1px #009900;
				background: #aaffaa;
				text-shadow: 0 1px 0 #77CC77;
				background: -webkit-gradient(linear, left top, left bottom, from(#337733), color-stop(0.15, #559955), to(#77CC77));
				background: -webkit-linear-gradient(top, #337733, #559955 15%, #77CC77);
				background: -moz-linear-gradient(top, #337733, #559955 15%, #77CC77);
				background: -ms-linear-gradient(top, #337733, #559955 15%, #77CC77);
				background: -o-linear-gradient(top, #337733, #559955 15%, #77CC77);
			} 
		

效果

七、图标按钮

这里使用sprites技术的配合，制作了一个200个图标的按钮效果。首先来看HTML的不同之处.

HTML Markup

			<div class="buttons"><a href="" class="button"><span class="icon iconNum">iconNum</span></a></div>
		

此处的“iconNum”是代表的“icon”编号，在这里指的是“icon1”至“icon200”。具体可以看下面两张图：

默认icon sprites图：

悬浮状态下的icon sprites图：

下面的样式中就需要使用到这两张图片，接下来看样式的写法吧：

CSS Code

			.ddm span.icon, 
			button span.icon, 
			.button span.icon {
				background-image: url(../images/google+-ui-sprite-gray.png);
				
				display: inline-block;
				margin: 0 7px;
				float: left;
				
				line-height: 18px;
				height: 18px;
				width: 18px;
				max-width: 18px;
				
				overflow: hidden;
				text-indent: -9999px;
				
				background-repeat: no-repeat;
				
				-webkit-transition: background-image 0.20s linear;
				-moz-transition: background-image 0.20s linear;
				-o-transition: background-image 0.20s linear;
				transition: background-image 0.20s linear;
			}
			.ddm:hover span.icon, 
			button:hover span.icon, 
			.button:hover span.icon {
				background-image: url(../images/google+-ui-sprite-colour.png);
			}
			/*=========================

			 *=======================*/
			 /* Sprite Row 1 */
			span.icon1 {background-position: -0px -0px;}

			span.icon36 {background-position: -270px -18px;}
			span.icon37 {background-position: -288px -18px;}
			span.icon38 {background-position: -306px -18px;}
			span.icon39 {background-position: -324px -18px;}
			span.icon40 {background-position: -342px -18px;}

			/* Sprite Row 3 */
			span.icon41 {background-position: -0px -36px;}
			span.icon42 {background-position: -18px -36px;}
			span.icon43 {background-position: -36px -36px;}
			span.icon44 {background-position: -54px -36px;}
			span.icon45 {background-position: -72px -36px;}

效果：

八、Tip按钮

制作这种按钮效果，就需jQuery的版本库以及TipTip jQuery Plugin(你可以到下载)。如果你准备好了这些东东，我们就开如下面的制作。

HTML Markup

			<div class="buttons">
			  <div class="tiptip">
			    <a class="button" title="Home"><span class="icon icon108"></span></a>
			  </div>
			</div>
		

这里有一个关键之处，那就是需要在“.button”元素中增加一个“title”属性，其属性值就是你希望在“tooltip”中显示的内容。如上面的代码所示，在“.button”元素中增加一个“title”属性，并且将其值设置为“Home”。

有了上面的结构后，还需要在“HTML”中调用前面准备好的jQuery的版本库以及TipTip jQuery Plugin。具体放哪，大家都知道，我就不多说了。

			<script src="js/jquery-1.6.2.js"></script>
			<script src="js/jquery.tiptip.js"></script>
		

这些准备好以后，就需要在有“tooltip按钮”地方调用“.tipTip()”函数。

			<script type="text/javascript">
				$(function(){
					//Launch TipTip tooltip
					$(".tiptip a.button, .tiptip button").tipTip();
				});
			</script>
		

上面是完成了“tooltip”功能，那么我们还需要给这些“tooltip按钮”赋予相应的样式。

CSS Code

			/* TipTip CSS - Version 1.2 (Modified) */

			#tiptip_holder {
				display: none;
				position: absolute;
				top: 0;
				left: 0;
				z-index: 99999;
			}

			#tiptip_holder.tip_top {
				padding-bottom: 5px;
			}

			#tiptip_holder.tip_bottom {
				padding-top: 5px;
			}

			#tiptip_holder.tip_right {
				padding-left: 5px;
			}

			#tiptip_holder.tip_left {
				padding-right: 5px;
			}

			#tiptip_content {
				font: bold 11px Helvetica, Arial, sans-serif;
				color: #FFF;
				padding: 7px;
				background: #000;
				border: 1px solid #FFF;
			}

			#tiptip_arrow, #tiptip_arrow_inner {
				position: absolute;
				border-color: transparent;
				border-style: solid;
				border-width: 6px;
				height: 0;
				width: 0;
			}

			#tiptip_holder.tip_top #tiptip_arrow {
				border-top-color: #fff;
			}

			#tiptip_holder.tip_bottom #tiptip_arrow {
				border-bottom-color: #fff;
			}

			#tiptip_holder.tip_right #tiptip_arrow {
				border-right-color: #fff;
			}

			#tiptip_holder.tip_left #tiptip_arrow {
				border-left-color: #fff;
			}

			#tiptip_holder.tip_top #tiptip_arrow_inner {
				margin-top: -7px;
				margin-left: -6px;
				border-top-color: #000;
			}

			#tiptip_holder.tip_bottom #tiptip_arrow_inner {
				margin-top: -5px;
				margin-left: -6px;
				border-bottom-color: #000;
			}

			#tiptip_holder.tip_right #tiptip_arrow_inner {
				margin-top: -6px;
				margin-left: -5px;
				border-right-color: #000;
			}

			#tiptip_holder.tip_left #tiptip_arrow_inner {
				margin-top: -6px;
				margin-left: -7px;
				border-left-color: #000;
			}

			/* Webkit Hacks  */
			@media screen and (-webkit-min-device-pixel-ratio:0) {	
				#tiptip_content {
					padding: 4px 8px 5px 8px;
					background-color: #000;
				}
				#tiptip_holder.tip_bottom #tiptip_arrow_inner { 
					border-bottom-color: #000;
				}
				#tiptip_holder.tip_top #tiptip_arrow_inner { 
					border-top-color: #000;
				}
			}
		

效果

九、带有标签的Icon按钮

这个效果只是结合了“默认按钮”和“Icon按钮”的风格。只需要在HTML做出一定的修改就Ok了。

HTML Markup

			<div class="buttons">
			  <a class="button" href="#"><span class="icon icon4"></span><span class="label">Profile</span></a>
			</div>
		

效果

十、下拉菜单按钮

制作这个效果，需要配合jQuery代码。首先我们看看其结构上的变化吧。

HTML Markup

			<div class="buttons">
			  <div class="dropdown">
			    <a href="#" class="button"><span class="label">File</span><span class="toggle"></span></a>
			    <div class="dropdown-slider">
			      <a href="#" class="ddm"><span class="label">New</span></a>
			      <a href="#" class="ddm"><span class="label">Save</span></a>
			    </div> 
			  </div>
			</div>
		

CSS Code

			div.dropdown {
				float: left;
				position: relative;
			}

			div.dropdown span.toggle {
				width: 19px;
				height: 16px;
				
				margin-left: 7px;
				margin-top: 1px;
				margin-right: 2px;
				padding-left: 8px;
				
				float: right;
				
				background: url(../images/toggle.png) top right no-repeat;
				border-left: 1px solid #D9D9D9;
				
				-webkit-transition: border-color .20s;
				-moz-transition: border .20s;
				-o-transition: border-color .20s;
				transition: border-color .20s;
			}
			div.dropdown span.toggle.active {
				background: url(../images/toggle.png) bottom right no-repeat;
			}
			div.dropdown 
			button:hover span.toggle, 
			.button:hover span.toggle {
				border-color: #C0C0C0;
			}

			div.dropdown-slider {
				display: none;
				
				overflow: hidden;
				
				margin: 0 7px 5px 7px;
				position: absolute;
				top: 34px;
				right: 0;
				
				background: #F2F2F2;
				
				border-right: solid 1px #D9D9D9;
				border-bottom: solid 1px #D9D9D9;
				border-left: solid 1px #D9D9D9;
				
				-webkit-border-bottom-right-radius: 2px;
				-webkit-border-bottom-left-radius: 2px;
				-moz-border-radius-bottomright: 2px;
				-moz-border-radius-bottomleft: 2px;
				border-bottom-right-radius: 2px;
				border-bottom-left-radius: 2px;
				
				-webkit-transition: border-color .20s;
				-moz-transition: border .20s;
				-o-transition: border-color .20s;
				transition: border-color .20s;
			}
			.left div.dropdown-slider {
				margin: 0 1px 5px 7px;
			}
			.middle div.dropdown-slider {
				margin: 0 1px 5px 1px;
			}
			.right div.dropdown-slider {
				margin: 0 7px 5px 1px;
			}
			div.dropdown-slider .ddm {
				display: block;
				background: #F2F2F2;
				color: #585858;
				
				text-decoration: none;
				text-shadow: 0 1px 0 #fff;
				font: bold 11px Helvetica, Arial, sans-serif;
				line-height: 18px;
				height: 18px;
				
				margin: 0;
				padding: 5px 6px 4px 6px;
				width: 100%;
				float: left;
				
				border-top: 1px solid #FFF;
				border-bottom: 1px solid #D9D9D9;
			}
			div.dropdown-slider .ddm:hover {
				background: #F4F4F4;
				border-bottom-color: #C0C0C0;
			}
			div.dropdown-slider .ddm:active {
				border-bottom-color: #4D90FE;
				color: #4D90FE;
				
				-moz-box-shadow:inset 0 0 10px #D4D4D4;
				-webkit-box-shadow:inset 0 0 10px #D4D4D4;
				box-shadow:inset 0 0 10px #D4D4D4;
			}
			div.dropdown-slider .ddm:last-child {
				border-bottom: none;
			} 
		

jQuery Code

			<script type="text/javascript">
					$(function(){
							// Toggle the dropdown menu's
							$(".dropdown .button, .dropdown button").click(function () {
								if (!$(this).find('span.toggle').hasClass('active')) {
									$('.dropdown-slider').slideUp();
									$('span.toggle').removeClass('active');
								}
							 
								// open selected dropown
								$(this).parent().find('.dropdown-slider').slideToggle('fast');
								$(this).find('span.toggle').toggleClass('active');
								
								return false;
							});		
							
						});
						
						// Close open dropdown slider by clicking elsewhwere on page
						$(document).bind('click', function (e) {
							if (e.target.id != $('.dropdown').attr('class')) {
								$('.dropdown-slider').slideUp();
								$('span.toggle').removeClass('active');
							}
						});
			</script>
