Adding a line of text on top of index page full-bleed image [Forte]

Site URL: https://heptagon-coconut-eb6t.squarespace.com/

Hi Squarespace Community,

I am building this website (https://heptagon-coconut-eb6t.squarespace.com) and would love to add a line of text in the bottom center of the screen, on top of my full-bleed images. Is that possible with custom code?

Would love some guidance here, as just adding <h1>Hello Test<h1> into my page header didn’t go too well.

Thanks a ton in advance. I’d be immensely appreciative of your help. Cheers,
Theo
