Thanks, @tikaram but I do not see the extra </div> you show in the screen capture, possibly as I have continued to add to that page. When I view the source, there are 79 occurrences of <div and 79 occurrences of </div so they are balanced. Also, the
<footer <span class=”html-attribute-name”>id</span>=”<span class=”html-attribute-value”>colophon</span>” <span class=”html-attribute-name”>class</span>=”<span class=”html-attribute-value”>site-footer</span>” <span class=”html-attribute-name”>role</span>=”<span class=”html-attribute-value”>contentinfo</span>”>
is inside the page div as is should be. However, the footer, which consists of the widgets in Footer Areas 1, 2, & 3, is still not responsive although the rest of the page is properly responsive. I have uploaded my screen capture to hbccc.org/wp/wp-content/uploads/2022/10/Screen-Shot-2022-10-18-at-8.06.24-AM.png which demonstrates there is no extra div in the area you indicated.
