--编辑--我没有看到原始帖子中的链接.抱歉的!将try 重写以反映实际问题

StopDesign在这个here上有一个很好的帖子.[edit 20091107] These were released as part of the 101: see the 102.

基本上，自定义按钮是使用简单的CSS创建的.

他最初使用了9个表来获得效果:

但后来，他在顶部和底部边框上使用了一个简单的1px左右边距来实现同样的效果.

渐变是通过使用三个层来伪造的:

所有代码都可以在Custom Buttons 3.1页找到.(虽然没有图像的渐变仅在Firefox和Safari中有效)

循序渐进的说明

1-插入以下CSS:

/* Start custom button CSS here
---------------------------------------- */
.btn {
  display:inline-block;
  background:none;
  margin:0;
  padding:3px 0;
  b或der-width:0;
  overflow:visible;
  font:100%/1.2 Arial,Sans-serif;
  text-dec或ation:none;
  col或:#333;
  }
* html button.btn {
  padding-bottom:1px;
  }
/* Immediately below is a temp或ary hack to serve the 
   following margin values only to Gecko browsers
   Gecko browsers add an extra 3px of left/right 
   padding to button elements which can't be overriden.
   Thus, we use -3px of left/right margin to overcome this. */
html:not([lang*=""]) button.btn {
  margin:0 -3px;
  }
.btn span {
  background:#f9f9f9;
  z-index:1;
  margin:0;
  padding:3px 0;
  b或der-left:1px solid #ccc;
  b或der-right:1px solid #bbb;
  }
* html .btn span {
  padding-top:0;
  }
.btn span span {
  background:none;
  position:relative;
  padding:3px .4em;
  b或der-width:0;
  b或der-top:1px solid #ccc;
  b或der-bottom:1px solid #bbb;
  }
.btn b {
  background:#e3e3e3;
  position:absolute;
  z-index:2;
  bottom:0;
  left:0;
  width:100%;
  overflow:hidden;
  height:40%;
  b或der-top:3px solid #eee;
  }
* html .btn b {
  top:1px;
  }
.btn u {
  text-dec或ation:none;
  position:relative;
  z-index:3;
  }

/* pill classes only needed if using pill style buttons ( LEFT | CENTER | RIGHT ) */
button.pill-l span {
  b或der-right-width:0;
  }
button.pill-l span span {
  b或der-right:1px solid #ccc;
  }
button.pill-c span {
  b或der-right-style:none;
  b或der-left-col或:#fff;
  }
button.pill-c span span {
  b或der-right:1px solid #ccc;
  }
button.pill-r span {
  b或der-left-col或:#fff;
  }

/* only needed if implementing separate hover state f或 buttons */
.btn:hover span, .btn:hover span span {
  curs或:pointer;
  b或der-col或:#9cf !imp或tant;
  col或:#000;
  }

/* use if one button should be the 'primary' button */
.primary {
  font-weight:bold;
  col或:#000;
  }

2-使用以下方式之一调用它(更多信息可在上面的链接中找到)

<a href="#" class="btn"><span><span><b>&nbsp;</b><u>button</u></span></span></a>

或

<button type="button" class="btn"><span><span><b>&nbsp;</b><u>button</u></span></span></button>
