我有工具栏的代码:
<div class='navbar navbar-fixed-top'>
<div class='navbar-inner'>
<div class='container'>
<a class='btn btn-navbar' data-target='.nav-collapse' data-toggle='collapse'>
<span class='icon-bar'></span>
<span class='icon-bar'></span>
<span class='icon-bar'></span>
</a>
<div class='nav-collapse'>
<ul class='nav'>
<li class='active'>
<a href='some_url'>My Home</a>
</li>
<li>
<a href='some_url'>Option 1 </a>
</li>
<li>
<a href='some_url'>Another option</a>
</li>
<li>
<a href='some_url'>Another option</a>
</li>
</ul>
</div>
</div>
</div>
</div>
它在Chrome上运行正常,但在Firefox和Safari上,工具栏无法渲染。知道为什么它不会渲染吗?
谢谢!
