How to remove the gray line in Review before Submit

I would also like to remove the gray borders between each field if we can make the fields display flex and then wrap.

Hi replumbpros, 

Thanks for reaching out to Jotform Support. Removing the gray line in Review before Submit section is possible by adding a CSS code. Let me show you how to do that:

• Open your form in Form Builder and click on the blue Paint Roller icon on the right side of the screen.
• Under the Styles tab, paste the code below into the Inject Custom CSS area.

/* Delete gray line in Review before Submit - 13919981 */ 

#previewContainer>ul>li:not(:last-child):nth-child(n+3) {

    border-top: 0px solid #ececec !important;

}

/* Ends here */

This is what it looks like after adding the CSS code:

Give it a try and let us know if you have any other questions.

Thanks Mikhail!
