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:

20120131143616_62352

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:
