How to use checkbox under description of any webform field? I am using webform module where I have a text field named Mobile Phone Number. 

I wanted to use checkbox under the text field as shown below:
 

The content can be written in the description of that text field. But how do I use the checkbox as I shown above.

Note: I tried to enter the html form tags in the description but didn't help.
You will create a check box component fields below mobile phone number fields after "yes|I am providing my express..." in OPTIONS . 
   Create Check box -> Options -> "yes|I am providing my express..."
     
and align with CSS code
