 css3样式表给我们做网站提供了更多的便捷性，以前做渐变背景，需要做成图片，然后设置成背景，而现在我们只需要在样式表里定义TABLE，TD或者DIV的样式就能实现渐变背景了：

线性渐变 - 从上到下:

  background: -webkit-linear-gradient(red, blue);    /* Safari 5.1 - 6.0 */
  background: -o-linear-gradient(red, blue);            /* Opera 11.1 - 12.0 */
  background: -moz-linear-gradient(red, blue);       /* Firefox 3.6 - 15 */
  background: linear-gradient(red, blue);                /* 标准的语法 */

 线性渐变 - 从左到右:

  background: -webkit-linear-gradient(left, red , blue);  /* Safari 5.1 - 6.0 */
  background: -o-linear-gradient(right, red, blue);         /* Opera 11.1 - 12.0 */
  background: -moz-linear-gradient(right, red, gradient(to right, red , blue);        /* 标准的语法 */

从左到右的线性渐变，带有透明度：

  background: -webkit-linear-gradient(left,rgba(255,0,0,0),rgba(255,0,0,1));   /* Safari 5.1 - 6 */
  background: -o-linear-gradient(right,rgba(255,0,0,0),rgba(255,0,0,1));         /* Opera 11.1 - 12*/
  background: -moz-linear-gradient(right,rgba(255,0,0,0),rgba(255,0,0,1));    /* Firefox 3.6 - 15*/
  background: linear-gradient(to right, rgba(255,0,0,0), rgba(255,0,0,1));       /* 标准的语法 */

径向渐变：

  background: -webkit-radial-gradient(red, green, blue);     /* Safari 5.1 - 6.0 */
  background: -o-radial-gradient(red, green, blue);             /* Opera 11.6 - 12.0 */
  background: -moz-radial-gradient(red, green, blue);        /* Firefox 3.6 - 15 */
  background: radial-gradient(red, green, blue);                 /* 标准的语法 */
