1.背景图片实现
Html代码:
- a { display: block; float:left; margin-left:5px; height: 37px;line-height: 37px; background: url(btn_bg.png) no-repeat 0px 0px; color: #d84700; text-decoration: none; padding-left:18px; }
- a span { display:block; background: url(btn_bg.png) no-repeat right 0px; padding-right:20px;}
- a:hover { background: url(btn_bg.png) no-repeat 0px -37px;}
- a:hover span{ background: url(btn_bg.png) no-repeat right -37px;}
Html代码:
- <p>
- <a href="#"><span>免费注册</span></a>
- <a href="#"><span>登录</span></a>
- <a href="#"><span>自适应宽度</span></a>
- </p>
原理就是做一个足够宽的背景，a和span都用同一张背景图，文字左侧部分显示的是a的背景，文字本身和右侧部分显示的是span的背景，拼接成一个按钮。
2.CSS3 火狐和Chrome实现
Html代码:
- .button1{
- -moz-border-radius:5px;
- -webkit-border-radius:5px;
- border-radius:5px;
- -moz-box-shadow:0 1px 0 rgba(0,0,0,0.3);
- -webkit-box-shadow:0 1px 0 rgba(0,0,0,0.3);
- box-shadow:0 1px 0 rgba(0,0,0,0.3);
- background: -moz-linear-gradient(19% 75% 90deg, #E0E0E0, #FAFAFA);
- background: -webkit-gradient(linear, left top, left bottom, from(#FAFAFA), to(#E0E0E0));
- color:#4A4A4A;
- float:left;
- font-family:arial,helvetica,sans-serif;

- background: -webkit-gradient(linear, left top, left bottom, from(#FAFAFA), to(#D6D6D6));
- }
