線性漸變css不能在導航欄中使用導航欄

Question

我在我的項目中使用了一個引導程序3，我有這個導航欄navbar-inverse。導航欄的背景顏色是黑色的，因爲它是相反的。我想要做的是更改該導航欄的背景顏色。我試過這段代碼，但它不工作。

.navbar-inverse { 
 
    margin-bottom: 0px; 
 
    -webkit-box-shadow: 0 8px 30px -6px black; 
 
    -moz-box-shadow: 0 8px 30px -6px black; 
 
    box-shadow: 0 8px 30px -6px black; 
 
    background: -moz-linear-gradient(center top, #2ebf16, #217812); 
 
    background: -webkit-gradient(linear, left top, left bottom, from(#2ebf16), to(#217812)); 
 
    background: -o-linear-gradient(top, #2ebf16, #217812); 
 
    filter: progid: DXImageTransform.Microsoft.gradient(startColorStr='#2ebf16', EndColorStr='#217812'); 
 
} 
 
.navbar-inverse .container { 
 
    width: 100%; 
 
    padding: 0; 
 
}

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css"> 
 

 
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script> 
 

 
<div class="container-fluid"> 
 
    <div class="navbar navbar-inverse navbar-static-top"> 
 
    <div class="container"> 
 
     <div class="navbar-header"> 
 
     <a href="#" class="navbar-brand">Land Tenure Services</a> 
 
     <button class="navbar-toggle" data-toggle="collapse" data-target=".navHeaderCollapse"> 
 
      <span class="icon-bar"></span> 
 
      <span class="icon-bar"></span> 
 
      <span class="icon-bar"></span> 
 
     </button> 
 
     </div>

Answer 1

你忘了，包括你的CSS規則的非前綴版（作爲最後一個）

background: linear-gradient(center top, #2ebf16, #217812);
