How do I let the user resize a column in bootstrap?
I made a responsive layout in Bootstrap like this.
<div class='container-fluid'>
<div class='row'>
<div class='col-xs-3 app-left-hand-side'>
<!-- tool bar goes here eventually -->
</div>
<div class='col-xs-9'>
<!-- the main content goes here -->
</div>
</div>
</div>
How can I let the client actively resize the columns by dragging along the border in the middle?
