首先来看看效果:

事例HTML代码:

<a href="#" class="button green">button</a><a href="#" class="button blue">button</a><a href="#" class="button gray">button</a>

如果没有 CSS ,那么上面的 HTML 执行起来是这样的:

开始 CSS3 的编写:

.button {    display: inline-block;    position: relative;    margin: 10px;    padding: 0 20px;    text-align: center;    text-decoration: none;    font: bold 12px/25px Arial, sans-serif;}

一些不同颜色的按钮样式:

.green {    color: #3e5706;    background: #a5cd4e;}/* Blue Color */.blue {    color: #19667d;    background: #70c9e3;}/* Gray Color */.gray {    color: #515151;    background: #d3d3d3;}

接下来开始用 CSS 处理圆角:

.button {    display: inline-block;    position: relative;    margin: 10px;    padding: 0 20px;    text-align: center;    text-decoration: none;    font: bold 12px/25px Arial, sans-serif;    text-shadow: 1px 1px 1px rgba(255,255,255, .22);    -webkit-border-radius: 30px;    -moz-border-radius: 30px;    border-radius: 30px;    -webkit-box-shadow: 1px 1px 1px rgba(0,0,0, .29), inset 1px 1px 1px rgba(255,255,255, .44);    -moz-box-shadow: 1px 1px 1px rgba(0,0,0, .29), inset 1px 1px 1px rgba(255,255,255, .44);    box-shadow: 1px 1px 1px rgba(0,0,0, .29), inset 1px 1px 1px rgba(255,255,255, .44);    -webkit-transition: all 0.15s ease;    -moz-transition: all 0.15s ease;    -o-transition: all 0.15s ease;    -ms-transition: all 0.15s ease;    transition: all 0.15s ease;}

现在的按钮圆润多了,看看:

还不够啊,没有立体效果,再完善完善:

/* Green Color */.green {    color: #3e5706;    background: #a5cd4e; /* Old browsers */    background: -moz-linear-gradient(top,  #a5cd4e 0%, #6b8f1a 100%); /* FF3.6+ */    background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#a5cd4e), color-stop(100%,#6b8f1a)); /* Chrome,Safari4+ */    background: -webkit-linear-gradient(top,  #a5cd4e 0%,#6b8f1a 100%); /* Chrome10+,Safari5.1+ */    background: -o-linear-gradient(top,  #a5cd4e 0%,#6b8f1a 100%); /* Opera 11.10+ */    background: -ms-linear-gradient(top,  #a5cd4e 0%,#6b8f1a 100%); /* IE10+ */    background: linear-gradient(top,  #a5cd4e 0%,#6b8f1a 100%); /* W3C */}/* Blue Color */.blue {    color: #19667d;    background: #70c9e3; /* Old browsers */    background: -moz-linear-gradient(top,  #70c9e3 0%, #39a0be 100%); /* FF3.6+ */    background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#70c9e3), color-stop(100%,#39a0be)); /* Chrome,Safari4+ */    background: -webkit-linear-gradient(top,  #70c9e3 0%,#39a0be 100%); /* Chrome10+,Safari5.1+ */    background: -o-linear-gradient(top,  #70c9e3 0%,#39a0be 100%); /* Opera 11.10+ */    background: -ms-linear-gradient(top,  #70c9e3 0%,#39a0be 100%); /* IE10+ */    background: linear-gradient(top,  #70c9e3 0%,#39a0be 100%); /* W3C */}/* Gray Color */.gray {    color: #515151;    background: #d3d3d3; /* Old browsers */    background: -moz-linear-gradient(top,  #d3d3d3 0%, #8a8a8a 100%); /* FF3.6+ */    background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#d3d3d3), color-stop(100%,#8a8a8a)); /* Chrome,Safari4+ */    background: -webkit-linear-gradient(top,  #d3d3d3 0%,#8a8a8a 100%); /* Chrome10+,Safari5.1+ */    background: -o-linear-gradient(top,  #d3d3d3 0%,#8a8a8a 100%); /* Opera 11.10+ */    background: -ms-linear-gradient(top,  #d3d3d3 0%,#8a8a8a 100%); /* IE10+ */    background: linear-gradient(top,  #d3d3d3 0%,#8a8a8a 100%); /* W3C */}

现在爽了,漂亮了,你喜欢这样的按钮吗?

为了让按钮更大一点,我们增加了个 big 样式:

<a href="#" class="button big green">sign in <span>One minute</span></a><a href="#" class="button big blue">sign in <span>One minute</span></a><a href="#" class="button big gray">sign in <span>One minute</span></a>
/* Big Button Style */.big {    padding: 0 40px;    padding-top: 10px;    height: 45px;    text-transform: uppercase;    font: bold 20px/22px Arial, sans-serif;}.big span {    display: block;    text-transform: none;    font: italic normal 12px/18px Georgia, sans-serif;    text-shadow: 1px 1px 1px rgba(255,255,255, .12);}

大按钮的效果:

我们还需要处理下当鼠标移到按钮上方时显示不同的效果:

.button:hover {    -webkit-box-shadow: 1px 1px 1px rgba(0,0,0,.29), inset 0px 0px 2px rgba(0,0,0, .5);    -moz-box-shadow: 1px 1px 1px rgba(0,0,0,.29), inset 0px 0px 2px rgba(0,0,0, .5);    box-shadow: 1px 1px 1px rgba(0,0,0,.29), inset 0px 0px 2px rgba(0,0,0, .5);}.button:active {    -webkit-box-shadow: inset 0px 0px 3px rgba(0,0,0, .8);    -moz-box-shadow: inset 0px 0px 3px rgba(0,0,0, .8);    box-shadow: inset 0px 0px 3px rgba(0,0,0, .8);}

效果如下:
