Twitter 引导标题上方的图片横幅

Question

我想在我的引导页面上方放置一个横幅。我的代码如下

HTML

<div class="masthead">
  <img src="images/gov-header.jpg"/>
</div>
<div class="navbar navbar-inverse navbar-fixed-top" role="navigation">
  <div class="container">
    <div class="navbar-header">
      <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
        <span class="sr-only">Toggle navigation</span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
      </button>
      <a class="navbar-brand" href="#">MST</a>
    </div>
    <div class="collapse navbar-collapse">
      <ul class="nav navbar-nav">
        <li class="active"><a href="index.html">Home</a></li>
        <li><a href="content.html">Divisions</a></li>
        <li><a href="#projects">Projects</a></li>
        <li><a href="#faqs">FAQs</a></li>
        <li><a href="#resources">Resources</a></li>
        <li><a href="#contact">Contact Us</a></li>
      </ul>
    </div><!--/.nav-collapse -->
  </div>

CSS

.masthead img{
  width:100%;
}

Answer 1

作为背景更好。

.masthead{
    height://height of bg;
    background-image:url("../images/gov-header.jpg");
    background-repeat:no-repeat;
}

希望这能给你一些想法。您可以根据要填充整个宽度还是仅填充容器长度来修改它。

更新 你必须改变

<div class="navbar navbar-inverse navbar-fixed-top" role="navigation">

到

<div class="navbar navbar-inverse" role="navigation">
