how to add div tags externally
if you refer to my suggestion, this
div would be added in the page editor, before your other code of the 'contact-us' section (and the corresponding
</div> obviously needs to be added after the section)
So in the style.css of my child theme, create a new div class for the css I want in this page? For instance div=home?
yes, just don't use the css class .home, as it is one of the automatically generated ones.
for instnace, if you added a
<div class="contact-us">
then in style.css you would use
.contact-us { .... }
