Oh I had that yesterday as well. I added the following custom CSS:
/* headers should use full width so that text align right/center/left works */
.entry-content h2, .entry-content h3, .entry-content h4 {
margin-left: auto;
margin-right: auto;
}
does the page title text resize with different resolutions? Mine doesn’t seem to so that when i resize my tabs the page title remains the same size font and ends up overlapping with my menu header
