Make column fixed position in bootstrap

Using Bootstrap, I have a grid column class="col-lg-3" that I want to place it in position:fixed while the other .col-lg-9 is normal position (scroll-able through the page).

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

</div>

Just the same way like the left column in LifeHacker.com You will see that the left part is fixed however I scroll though the page.

I use bootstrap v3.1.1

<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.

in Bootstrap 3 class="affix" works, but in Bootstrap 4 it does not. I solved this problem in Bootstrap 4 with class="sticky-top" (using position: fixed in CSS has its own problems)

code will be something like this:

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

Updated for Bootstrap 4

Bootstrap 4 now includes a position-fixed class for this purpose so there is no need for additional CSS...

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