Customize css/html using code from codepen.io

Is there a way to completely customize the css/html using a code from codepen.io (for example : http://codepen.io/daliannyvieira/pen/xOygEW) ?

I tried to copy paste the html/css but it seems there is conflict with css from jotform. Is there a way to empty all css of jotform ?

Here is the usecase : http://screencast-o-matic.com/watch/cDQ3X8jqu8

Since the field classes are different, it would not be possible to directly apply that CSS to your form.  The styles that were not for classes specific to the form could be copied directly.

However, anything that they used a specified class for would need to be updated for the specific JotForm fields.

If you are looking to apply a theme to your form, there are several available both for free and paid in our theme store:
