Answer 1

使用此代码，这将适用于IE 10，google chrom 26.0，fire fox 16.0，opera 12.1和safari 6.1：

  width:100%;
  height:3px;
  background: -webkit-radial-gradient(#7B7878 1%, #BBBBBB 30%, #CCCCCC 40%, #FFF 70%);
  background: -o-radial-gradient(#7B7878 1%, #BBBBBB 30%, #CCCCCC 40%, #FFF 70%);
  background: -moz-radial-gradient(#7B7878 1%, #BBBBBB 30%, #CCCCCC 40%, #FFF 70%);
  background: radial-gradient(#7B7878 1%, #BBBBBB 30%, #CCCCCC 40%, #FFF 70%);

并根据需要提供相同的结果。
