利用CSS的Clip属性来创造多彩文字

原理

将二个相同而色彩不同的文字重合在一起，通过分别给其加 clip 属性，使上面和下面的文字被剪切位置不同，从而产生二种不同的色彩。

clip : 摘自苏沈小雨CSS手册

clip : auto | rect ( number number number number )  参数：  auto : 　对象无剪切rect ( number number number number ) : 依据上-右-下-左的顺序提供自对象左上角为(0,0)坐标计算的四个偏移数值，其中任一数值都可用auto替换，即此边不剪切  说明：  检索或设置对象的可视区域。区域外的部分是透明的。必须将position的值设为absolute，此属性方可使用。

测试环境

Firefox1.5、IE6.0、Opera8.5、IE5.01绿色版通过。

    clip: rect(18px auto auto auto);
}
.textTop {
    color: #CC0000;
    position: absolute;
    left: 3em;
    top: 1em;
    font: 26px Century Gothic,Arial, Helvetica, sans-serif;
    clip: rect(0 auto 18px 0);
}
.container {
    width: 28em;
    height: 5em;
    margin: 1em auto;
    position: relative;
    background: #F6F6F6;
