Another Q for targeting a block & changing font, on a specific page

Site URL: https://heptagon-bugle-5sad.squarespace.com/

Here's yet another basic CSS question over how to target and change the font of one div block on a particular page. Sorry for redundancy. Site is on 7.1 and at https://heptagon-bugle-5sad.squarespace.com/ and password is 4c5sad

Under section[data-section-id="62d1ca1f7242da41460f5e9f"] of the homepage, I need to change the title "Subheadline to Who We Are" there to a header style, or rather to just this:

font-family: 'barlow_semi_condensedblack', sans-serif !important;
letter-spacing: -1px !important;

Help.

Ah—div id then class then html tag. That worked of course, and as always thank you one thousand @tuanphan
