CSS3制作分享按钮
发布于
大漠
Nicolas Gallagher在Pure CSS GUI icons中使用纯CSS3制作的各种ICON的DEMO，让我再次领会了CSS3的强大。
大家看到这个DEMO一定也会觉得CSS3很强大吧，同时也会自叹自己怎么就没有Nicolas Gallagher这种水平呢？其实只是自己没有他那样的思维，不敢去想，也不敢去尝试。别的不多说，说了也没意思，还是切入今天的主题吧。今天我在Nicolas Gallagher思路上也仿制了几个常见共享按钮的效果，希望大家喜欢。
看到上面的效果，大家肯定想看看是怎么实现的吧，那还等什么呢？直接往下看。
HTML Markup
这里的结构就很简单了，上面的DEMO仅采用了一个标签，你可以是HTML中的任何标签，不过此处为了说明DEMO的实现，我采用的是一个列表形式。
<ul> <li class="facebook"><a href="#non" title="Share on Facebook">Facebook</a></li> <li class="twitter"><a href="#non" title="Share on Twitter">Twitter</a></li> <li class="rss"><a href="#non" title="Subscribe to the RSS feed">RSS</a></li> <li class="flickr"><a href="#non" title="Share on Flickr">Flickr</a></li> <li class="delicious"><a href="#non" title="Bookmark on Delicious">Delicious</a></li> <li class="linkedin"><a href="#non" title="Share on LinkedIn">LinkedIn</a></li> <li class="google"><a href="#non" title="Bookmark with Google">Google</a></li> <li class="orkut"><a href="#non" title="Share on Orkut">Orkut</a></li> <li class="technorati"><a href="#non" title="Add to Technorati">Technorati</a></li> <li class="netvibes"><a href="#non" title="Add to NetVibes">NetVibes</a></li> <li class="google-plus"><a href="#non" title="Add to google+">Google+</a></li> <li class="yahoo"><a href="#non" title="Add to yahoo">Yahoo</a></li> <li class="tumblr"><a href="#non" title="Add to tumblr">Tumblr</a></li> </ul>
在具体写每个按钮之前，先给这些按钮一些基本样式
Base Css
body {
padding:0;
margin:0;
font:1em/1.4 Cambria, Georgia, sans-serif; color:#333;
background:#fff;
}
ul {
list-style:none;
padding:0;
margin:0;
overflow:hidden;
font:0.875em/1 Arial, sans-serif;
}
ul li {
float:left;
width:66px;
height:66px;
margin:20px 20px 0 0;
}
ul li a {
display:block;
width:64px;
height:64px;
overflow:hidden;
border:1px solid transparent;
line-height:64px;
text-decoration:none;
border-radius:5px;
}
ul li a:hover,
ul li a:focus,
ul li a:active {
opacity:0.8;
border-color:#000;
}
接下来分别看看每个按钮的代码：
一、Facebook
.facebook a {
position: relative;
border-color: #3c5a98;
text-transform: lowercase;
text-indent: 34px;
letter-spacing: 10px;
font-weight: bold;
font-size: 64px;
line-height: 66px;
color: #fff;
background: #3c5a98;
box-shadow: 0 0 4px rgba(0,0,0,0.4);
}
Facebook这个按钮是相当的简单，没有什么特别之处。在这个效果中，采用了“text-indent”来控制文字的显示位置，“letter-spacing”配合“li”中的“overflow”来隐藏其他的字母（这样的使用在后面的按钮中都有或多或少的用到）。
二、Twitter
.twitter a {
position: relative;
border-color: #a8eaec;
text-indent: 20px;
letter-spacing: 40px;
font: bold 60px/1 Tahoma,sans-serif;
line-height: 60px;
background: #daf6f7;
text-shadow: 3px 3px 1px #fff, -3px -3px 1px #fff, 3px -3px 1px #fff, -3px 3px 1px #fff;
box-shadow: 0 0 4px rgba(0,0,0,0.4);
background-image: -webkit-gradient(linear, left top,left bottom,from(#dbf7f8),to(#88e1e6));
background-image: -webkit-linear-gradient(top,#dbf7f8,#88e1e6);
background-image: -moz-linear-gradient(top,#dbf7f8,#88e1e6);
background-image: -o-linear-gradient(top,#dbf7f8,#88e1e6);
background-image: -ms-linear-gradient(top,#dbf7f8,#88e1e6);
background-image: linear-gradient(top,#dbf7f8,#88e1e6);
text-transform: lowercase;
color: #76ddf8;
}
Twitter按钮的效果有两个关键之处，给文字使用了多重文字阴影，而且背景使用的是渐变制作。
三、RSS
.rss a {
position: relative;
width: 60px;
padding: 0 2px;
border-color: #ea6635;
text-transform: lowercase;
text-indent: -186px;
font-size: 64px;
font-weight: bold;
background: #e36443;
box-shadow: 0 0 4px rgba(0,0,0,0.4);
background-image: -webkit-gradient(linear,left top, left bottom,from(#f19242),to(#e36443));
background-image: -webkit-linear-gradient(top,#f19242,#e36443);
background-image: -moz-linear-gradient(top,#f19242,#e36443);
background-image: -o-linear-gradient(top,#f19242,#e36443);
background-image: -ms-linear-gradient(top,#f19242,#e36443);
background-image: linear-gradient(top,#f19242,#e36443);
}
/*圆点*/
.rss a::before {
content:"\00a0";
position: absolute;
bottom: 10px;
left: 10px;
width: 12px;
height: 12px;
background: #fff;
border-radius: 12px;
}
/*弧形*/
.rss a::after {
content:"\00a0";
position: absolute;
bottom: 10px;
left: 10px;
height: 22px;
width: 22px;
border: 24px double #fff;
border-width: 24px 24px 0 0;
border-radius: 0 50px 0 0;
}
RSS制作效果相对来说复杂一些了，在“a”元素上制作了按钮的背景色，而其中圆点和两个弧形是通过CSS3的伪元素实现的。
四、Flickr
.flickr a {
position:relative;
border-color:#d2d2d2;
text-indent:-9000px;
font-size:108px;
font-weight:bold;
color:#fff;
background:#fff;
box-shadow:0 0 4px rgba(0,0,0,0.4);
background-image:-webkit-gradient(linear, left top, left bottom, from(#fff), to(#d2d2d2));
background-image:-webkit-linear-gradient(top, #fff, #d2d2d2);
background-image:-moz-linear-gradient(top, #fff, #d2d2d2);
background-image:-o-linear-gradient(top, #fff, #d2d2d2);
background-image:-ms-linear-gradient(top, #fff, #d2d2d2);
background-image:linear-gradient(top, #fff, #d2d2d2);
}
/*蓝色圆点*/
.flickr a::before {
content:"\00a0";
position:absolute;
top:50%;
left:30%;
width:20px;
height:20px;
margin:-10px 0 0 -10px;
background:#085ec5;
border:1px solid #003c84;
border-radius: 20px;
background-image:-webkit-gradient(linear, left top, left bottom, from(#005cc6), to(#003d83));
background-image:-webkit-linear-gradient(top, #005cc6, #003d83);
background-image:-moz-linear-gradient(top, #005cc6, #003d83);
background-image:-o-linear-gradient(top, #005cc6, #003d83);
background-image:-ms-linear-gradient(top, #005cc6, #003d83);
background-image:linear-gradient(top, #005cc6, #003d83);
}
/*红色圆点*/
.flickr a::after {
content:"\00a0";
position:absolute;
top:50%;
right:30%;
width:20px;
height:20px;
margin:-10px -10px 0 0;
border:1px solid #ba0060;
background:#fd1e93;
border-radius:20px;
background-image:-webkit-gradient(linear, left top, left bottom, from(#fd1e93), to(#cb026c));
background-image:-moz-linear-gradient(top, #fd1e93, #cb026c);
background-image: -webkit-linear-gradient(top, #fd1e93, #cb026c);
background-image: -o-linear-gradient(top, #fd1e93, #cb026c);
background-image: -ms-linear-gradient(top, #fd1e93, #cb026c);
background-image: linear-gradient(top, #fd1e93, #cb026c);
}
Flickr上的两上圆点效果也是通过伪元素实现：“::before”制作了蓝点，“::after”制作了粉红点。
五、Delicious
.delicious a {
position:relative;
border-color:#d2d2d2;
text-align:center;
text-indent:-9000px;
font-size:108px;
font-weight:bold;
color:#fff;
background:#fff;
box-shadow:0 0 4px rgba(0,0,0,0.4);
background-image:-webkit-gradient(linear, left top, left bottom, from(#fff), to(#d1d1d1));
background-image:-webkit-linear-gradient(top, #fff, #d1d1d1);
background-image:-moz-linear-gradient(top, #fff, #d1d1d1);
background-image:-o-linear-gradient(top, #fff, #d1d1d1);
background-image:-ms-linear-gradient(top, #fff, #d1d1d1);
background-image:linear-gradient(top, #fff, #d1d1d1);
}
/*右上角蓝色方块*/
.delicious a::before {
content:"\00a0";
position:absolute;
top:0;
right:0;
width:30px;
height:30px;
border:1px solid #0060ce;
background:#085ec5;
border-radius:0 4px 0 0;
background-images:-webkit-gradient(linear, left top, left bottom, from(#0060ce)), to(#003b7f));
background-images:-webkit-linear-gradient(top, #0060ce, #003b7f);
background-images:-moz-linear-gradient(top, #0060ce, #003b7f);
background-images:-o-linear-gradient(top, #0060ce, #003b7f);
background-images:-ms-linear-gradient(top, #0060ce, #003b7f);
background-images:linear-gradient(top, #0060ce, #003b7f);
}
/*左下角黑色方块*/
.delicious a::after {
content:"\00a0";
position:absolute;
bottom:0;
left:0;
width:30px;
height:30px;
border:1px solid #000;
background:#000;
border-radius: 0 0 0 4px;
background-image:-webkit-gradient(linear, left top, left bottom, from(#212121), to(#000));
background-image:-webkit-linear-gradient(top, #212121, #000);
background-image:-moz-linear-gradient(top, #212121, #000);
background-image:-o-linear-gradient(top, #212121, #000);
background-image:-ms-linear-gradient(top, #212121, #000);
background-image:linear-gradient(top, #212121, #000);
}

font-size:64px;
font-weight:bold;
color:#fff;
background:#0c6596;
box-shadow:0 0 4px rgba(0,0,0,0.4);
background-image:-webkit-gradient(linear, left top, left bottom, from(#5babcb), to(#0c6596));
background-image:-webkit-linear-gradient(top, #5babcb, #0c6596);
background-image:-moz-linear-gradient(top, #5babcb, #0c6596);
background-image:-ms-linear-gradient(top, #5babcb, #0c6596);
