I see that, interesting, not sure why yet.
Any chance we can try the heading with only the following in Custom CSS, nothing else:
/* Content Heading */
.single .entry-header h1.entry-title, .page .site-content > .entry-header h1.entry-title, .blog .page-header h1.page-title, .search-results .page-header h1.page-title, .search-no-results .page-header h1.page-title, .error404 .page-header h1.page-title {
width: 100%;
text-align: center;
}
I know the full image won’t be there but in my testing now it does seem to look quite good. What do you think?
