Ok, here is the form URL:
Survey

What we want to do is enclose this group of fields:

formID_fieldID

If we can get a red border and a shaded background around the group of fields, the aesthetics can easily be fine-tuned.

Here is the missing HTML blocks:
HTML-1

<style type="text/css">
body .gform_wrapper .gform_body .gform_fields #field_6_25.gfield .ginput_complex {border: 1px solid red}
body .gform_wrapper .gform_body .gform_fields #field_6_36.gfield .ginput_complex {border: 1px solid red}
body .gform_wrapper .gform_body .gform_fields #field_6_37.gfield .ginput_complex {border: 1px solid red}
body .gform_wrapper .gform_body .gform_fields #field_6_38.gfield .ginput_complex {border: 1px solid red}
</style>
</li>
</ul>
<div class="my-box-style">
<ul class="gform_fields top_label description_below">
<li>

HTML-2

</li>
</ul>
</div>
<ul>
<li>

 

Thanks in advance!

Please share a URL to the page on your site where we can see the form, and let us know exactly which fields (by name or field ID) you want to target specifically. Thank you.

Also, your HTML was stripped from the ticket. Please submit that when you send the URL. Thank you.

Form Page URL

Issue
*** Goal:
On a form with 10 fields, I’d like to put a 2px box around the last 2 fields and color this box 20% yellow to produce an “administrative use only” section, where calculated fields will do their thing.

*** Situation:
After checking through the old forum posts (https://www.gravityhelp.com/forums/topic/adding-a-box-around-a-group-of-fields) and the CSS Targeting Samples page (https://www.gravityhelp.com/documentation/article/css-targeting-samples/), I added the HTML-1 block in an HTML form field just before Field 8 and the HTML-2 block after field 10.

No change.

What do I have to do differently? There must be someplace to define the box style characteristics, right?

Thanks in advance!
