Constraining CSS class styles to apply only to a given id - css

Question

I am trying to use two Twitter Bootstrap navs on the same page. I have written some css to style them. Problem is, I want the css to apply to just one of the navs. I tried to use css ids to distinguish the two navs, but am having trouble getting the selectors right. Can anyone help?
Here's a simplified version of what I'm trying to do: http://jsfiddle.net/XVReX/
HTML:
<div id="something" class="navbar">
<div class="navbar-inner">
<div class="container">
<ul class="nav">
<li id="selectEventStep"><a>Select Event</a>
</li>
<li id="selectPriceStep"><a>Select Price</a>
</li>
<li id="confirmSwapStep"><a>Confirm Swap</a>
</li>
</ul>
</div>
</div>
</div>
<div class="navbar">
<div class="navbar-inner">
<div class="container">
<ul class="nav">
<li id="selectEventStep"><a>Select Event</a>
</li>
<li id="selectPriceStep"><a>Select Price</a>
</li>
<li id="confirmSwapStep"><a>Confirm Swap</a>
</li>
</ul>
</div>
</div>
</div>
CSS:
#something.navbar #something.navbar-inner {
padding: 0;
background-image: -webkit-linear-gradient(top, #E5665D, #C4564F);
}
#something.navbar #something.nav li a {
font-weight: bold;
text-align: center;
color: #FFE2E0;
text-shadow: 0 1px 0 #000;
;
}
#something.navbar #something.nav li a:hover {
color: #fff;
}
Thanks!

Answer 1

The selectors are more complicated than necessary and the syntax is incorrect - you can override bootstrap.css by instead using:
#something .navbar-inner { }
#something .nav li a{ }
#something .nav li a:hover { }

Answer 2

I rewrote the entire style sheet to apply the style only on those elements with a class name .bootstrap using sass compiler and regular expression which looks like this
audio.bootstrap:not([controls]) {
display: none;
}
html.bootstrap {
font-size: 100%;
-webkit-text-size-adjust: 100%;
-ms-text-size-adjust: 100%;
}
a.bootstrap:focus {
outline: thin dotted #333;
outline: 5px auto -webkit-focus-ring-color;
outline-offset: -2px;
}
I haven't checked everything but I think it works alright.
