Field Confirmation & Dynamic Textbox Widgets - How to add error state?

Is it possible to add error states to the Field Confirmation and Dynamic Textbox widgets using CSS? 

Unfortunately it is not possible to add error states in the Dynamic Textbox and Field Confirmation widgets. These widgets are loaded separately from the main form. You can add error state to the field using javascript, however it is not possible to add javascript to jotform. The only way to add javascript to the form is if you download the full source code of the form and host it in your server. To do so, simply follow this guide: How to get the Full Source Code of your Form.
