Make column fixed position in bootstrap

<div class="row">
    <div class="col-lg-3">
       <div class="affix">
           fixed position 
        </div>
    </div>
    <div class="col-lg-9">
       Normal data enter code here
    </div>
</div>

iterating over Ihab's answer, just using position:fixed and bootstraps col-offset you don't need to be specific on the width.

<div class="row">
    <div class="col-lg-3" style="position:fixed">
        Fixed content
    </div>
    <div class="col-lg-9 col-lg-offset-3">
        Normal scrollable content
    </div>
</div>

Following the solution here http://jsfiddle.net/dRbe4/,

<div class="row">
    <div class="col-lg-3 fixed">
        Fixed content
    </div>
    <div class="col-lg-9 scrollit">
        Normal scrollable content
    </div>

 </div>

I modified some css to work just perfect:

.fixed {
        position: fixed;
        width: 25%;
}
.scrollit {
        float: left;
        width: 71%
}

Thanks @Lowkase for sharing the solution.
