Hi, you can create 3-column fixed layout using the following code in Bootstrap 2.3.2:
<div class="container">
<div class="row">
<div class="span4">
<!--column one-->
</div>
<div class="span4">
<!--column two-->
</div>
<div class="span4">
<!--column three-->
</div>
</div>
</div>
To make them liquid just replace the class “container” with “container-fluid” and “row” with “row-fluid”.
