Yii-bootstrap TbMenu修改默认背景颜色(background-color)

google，百度了半天，也尝试修改了很多地方的class,background-color，但是毫无结果。

最后用firedebug发现除了background-color之外，还有其它几个属性：

 background-image: 
  background-image:
  background-image:
  background-image:
  background-image:
  background-image:
  background-repeat

在stack overflow找到了解决办法。

在css下新建style.css，并覆写bootstrap的.navbar-inner属性:

.navbar-inner {
	background-color:#f58220;
  /* Gradients for modern browsers, replace as you see fit */
  background-image: -moz-linear-gradient(top, #f58220, #fedcbd);
  background-image: -ms-linear-gradient(top, #f58220, #fedcbd);
  background-image: -webkit-gradient(linear, 0 0, 0 100%, from(#f58220), to(#fedcbd));
  background-image: -webkit-linear-gradient(top, #f58220, #fedcbd);
  background-image: -o-linear-gradient(top, #f58220, #fedcbd);
  background-image: linear-gradient(top, #f58220, #fedcbd);
  background-repeat: repeat-x;

  /* IE8-9 gradient filter */
  filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#333333', endColorstr='#fedcbd', GradientType=0);
}
