我正在尝试使用以下代码：
<nav class="navbar navbar-fixed-top">
<div class="container">
<div id="navbar" class="navbar-collapse">
<ul class="nav navbar-nav">
<li>About</li>
<li>Projects</li>
<li>Contact Me</li>
</ul>
</div>
</div>
</nav>
However, the navbar is still scrollable when I apply it to my own webpage. You can view the page here:

I think there is something wrong with the way your are loading in your bootstrap. Make sure you call jquery before you call the bootstrap files. If nothing works you could always add the fixed positioning yourself:
我认为您在引导程序中加载的方式有问题。确保在调用引导文件之前调用 jquery。如果没有任何效果，您可以随时自己添加固定定位：
.navbar-fixed-top {
position:fixed !important;
}
