How i add html -webkit and -moz for GECO and WEBKIT in a form.

Hello lpaulmp,

I am not sure if I have understood your question correctly. 

Do you want to add the support for a non-Javascript scripting engine of Gecko or Webkit? If you want to add script code to support these, unfortunately it is not possible. For security reason injection of script code is restricted in JotForm.

However, you can still inject the custom css code to support webkit. The following guide should inject the custom css code in your form:  http://www.jotform.com/help/117-How-to-Inject-Custom-CSS-Codes

Hope this helps.

Do get back to us if you meant to ask something else.

Thank you!
