html - Creating a fixed sidebar alongside a centered Bootstrap 3 grid

Question

I'd like to create a fixed sidebar that exists outside my centered Bootstrap Grid. The challenge I face when attempting to do this is determining what additional styles to apply/overwrite to my .container so that it doesn't overlap my sidebar when the screen is resized.

For starters I'm only using the grid portion of the css framework so the .container, .row and .col-md-12 is code pulled from the bootstrap.css file itself and is not custom. Also keep in mind I'm using Bootstrap 3, so please, no suggestions for a fluid grid solution for Bootstrap 2 that is often asked about in previous threads.

HTML

<div id="left-nav"></div>
<div class="container">
   <div class="row">
      <div class="col-md-12">
         <p>Lorem ipsum dolor sit amet, nunc dictum at.</p>
      </div>
   </div>
</div>

CSS

html, body {
  height: 100%;
  width: 100%;
}
#left-nav {
  background: #2b2b2b;
  position: absolute;
  top: 0px;
  left: 0px;
  height: 100%;
  width: 250px;
}

As drew_w said, you can find a good example here.

HTML

<div id="wrapper">
    <div id="sidebar-wrapper">
        <ul class="sidebar-nav">
            <li class="sidebar-brand"><a href="#">Home</a></li>
            <li><a href="#">Another link</a></li>
            <li><a href="#">Next link</a></li>
            <li><a href="#">Last link</a></li>
        </ul>
    </div>
    <div id="page-content-wrapper">
        <div class="page-content">
            <div class="container">
                <div class="row">
                    <div class="col-md-12">
                        <!-- content of page -->
                    </div>
                </div>
            </div>
        </div>
    </div>
</div>

CSS

#wrapper {
  padding-left: 250px;
  transition: all 0.4s ease 0s;
}

#sidebar-wrapper {
  margin-left: -250px;
  left: 250px;
  width: 250px;
  background: #CCC;
  position: fixed;
  height: 100%;
  overflow-y: auto;
  z-index: 1000;
  transition: all 0.4s ease 0s;
}

#page-content-wrapper {
  width: 100%;
}

.sidebar-nav {
  position: absolute;
  top: 0;
  width: 250px;
  list-style: none;
  margin: 0;
  padding: 0;
}

@media (max-width:767px) {

    #wrapper {
      padding-left: 0;
    }

    #sidebar-wrapper {
      left: 0;
    }

    #wrapper.active {
      position: relative;
      left: 250px;
    }

    #wrapper.active #sidebar-wrapper {
      left: 250px;
      width: 250px;
      transition: all 0.4s ease 0s;
    }

}
