Twitter Bootstrap에서 고정 너비 사이드바 및 유동 너비 콘텐츠 영역을 어떻게 얻을 수 있습니까?

<div class="container-fluid fill">
    <div class="row-fluid">
        <div class="fixed">  <!-- Fixed width -->
            ...
        </div>
        <div class="hero-unit filler">  <!-- Removed spanX class -->
            ...
        </div>
    </div>
</div>

.fixed {
    width: 150px;  /* Fixed width */
    float: left;
}

.fixed + div {
    margin-left: 150px;  /* Match fixed width */
    overflow: hidden;
}

/* CSS to ensure sidebar and content are same height (optional) */

html, body {
    height: 100%;
}

.fill { 
    min-height: 100%;
    position: relative;
}

.filler::after{
    background-color:inherit;
    bottom: 0;
    content: "";
