Those should **not** be in Additional CSS.

Replace the entire Additional CSS with this:

```css
/* ===== Hide all page titles for this theme ===== */

.page .entry-title,
.page .page-title,
.page h1 {
    display: none !important;
}

/* ===== Remove space left by title ===== */

.page .entry-header {
    display: none !important;
}

.page .site-content {
    padding-top: 0 !important;
    margin-top: 0 !important;
}

/* ===== Remove large default title/content spacing site-wide ===== */

#content,
.site-content,
.content-area,
.site-main,
article,
.entry-content {
    padding-top: 0 !important;
    margin-top: 0 !important;
}

/* ===== Homepage: reduce desktop space below header ===== */

.home #content,
.home .site-content,
.home .content-area,
.home .site-main,
.page-id-7 #content,
.page-id-7 .site-content,
.page-id-7 .content-area,
.page-id-7 .site-main {
    padding-top: 0 !important;
    margin-top: -60px !important;
}

/* ===== Mobile: undo homepage pull-up so header does not overlap ===== */

@media (max-width: 768px) {
  .home #content,
  .home .site-content,
  .home .content-area,
  .home .site-main,
  .page-id-7 #content,
  .page-id-7 .site-content,
  .page-id-7 .content-area,
  .page-id-7 .site-main {
    margin-top: 0 !important;
    padding-top: 10px !important;
