You don't need any special requirement for this if you have basic knowledge of html, css and javascript so you can easily put all codes on your page and modify as well.

When you add this form on your webpage then put all html in your code, css in stylesheet and also javascript in your js file but please check first any variable name and css class if uses again then you know what i mean. You can easily use all benifits of this form now.
