can I add a third column to add a text

Hi,
Is it possible to add a third column to add a text as per screen shot below? my site is www.ecctz.com

 

Hello, honory2009!

Please follow the screenshot given below.

PHP:

<div class="grid_8">     
        <p class="footer_text">This site was developed by <span>xyz.com</span></p>
        </div>

Now, paste the CSS code in custom css section.

Code:

p.footer_text span {
  color: green;
}

Thanks,
Praveen
