How to use putting validation message underneath a control using backbone validation

How to use putting validation message underneath a control using backbone
validation

I am using backbone.validation.js
I am able to implement this as shown in the demo here

So, I am able to show the error messages next to the field. I want to be
able to show these message underneath the controls.
I checked the HTML generated for these messages, it reads
<span class="help-inline error-message">
Please provide your first name
</span>
I tried doing through CSS, it could do it but it gets a little messy.
Wanted to know if there is already a provision for this which I may have
missed.
Please advice.
