Post top first line styling

Hi, this should do it, but since you didn’t give a link to your site, I had to work off of the demo site and don’t know what customizations you may have made that could affect things.

.format-standard:not(.post-password-required) .entry-content > p:first-of-type:not(.no-emphasis)::first-line, .page:not(.post-password-required) .entry-content > p:first-of-type:not(.no-emphasis)::first-line, .emphasis::first-line {
  font-size: 1.2em;
  font-family: initial;
  font-weight: normal;
  color: #363431;
  letter-spacing: initial
}

.format-standard:not(.post-password-required) .entry-content > p:first-of-type:not(.no-emphasis)::first-letter, .page:not(.post-password-required) .entry-content > p:first-of-type:not(.no-emphasis)::first-letter, .emphasis::first-letter {
  font-size: 1.1em;
  color: #363431;
  font-weight: normal;
  line-height: 2;
  margin: 0;
  float: none;
  letter-spacing: initial;
}

Hooray and you are welcome!
