Bootstrap Navbar transparaent

Question

这是我的CSS;如何将导航栏标题设置为透明。我曾尝试设置background-color; transparent;但是这不会改变任何东西

.navbar-inner { 


min-height: 40px; 
    padding-right: 20px; 
    padding-left: 20px; 
    background-color: #fafafa; 
    background-image: -moz-linear-gradient(top, #ffffff, #f2f2f2); 
    background-image: -webkit-gradient(linear, 0 0, 0 100%, from(#ffffff), to(#f2f2f2)); 
    background-image: -webkit-linear-gradient(top, #ffffff, #f2f2f2); 
    background-image: -o-linear-gradient(top, #ffffff, #f2f2f2); 
    background-image: linear-gradient(to bottom, #ffffff, #f2f2f2); 
    background-repeat: repeat-x; 
    border: 1px solid #d4d4d4; 
    -webkit-border-radius: 4px; 
    -moz-border-radius: 4px; 
      border-radius: 4px; 
    filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#ffffffff', endColorstr='#fff2f2f2', GradientType=0); 
    *zoom: 1; 
    -webkit-box-shadow: 0 1px 4px rgba(0, 0, 0, 0.065); 
    -moz-box-shadow: 0 1px 4px rgba(0, 0, 0, 0.065); 
      box-shadow: 0 1px 4px rgba(0, 0, 0, 0.065);

试试这个

.navbar-inner { 
background-color: #ffffff; 
opacity: 0.6; 
filter: alpha(opacity=60); /* For IE8 and earlier */ 
}
