Hide paragraphs on Review and Submit

Hi,

I'd like to hide paragraphs of text within the form on review and submit. I've attempted adding the code to the Form Designer however it hides the paragraphs in build mode and not at Review and Submit. I'm unable to share the form as it is confidential data.

This is the code I copied from another support solution:

.form-html{

  display:none;

}

#previewContainer > ul > li.html{

 visibility: visible!important;

}
