On some of my pages that are not using the page header addon, the portion of HTML (see below) above my content area has a mysterious height of 8px. This is causing a gap between the nav bar and content. If I modify the class below, this has direct impact on the header content. How can I ensure that the page header div will remain at 0px when no page header image/content is being used?
HTML pulled from element: <div class="page-header-image grid-container grid-parent generate-page-header"><img src="" width="" height="" alt=""></div>
