Example of an define-derived-mode from emacs, which means it’s an expansion of another already existing mode. This example uses the built-in text-mode
(define-derived-mode aa-edit-mode text-mode "AA-Edit"
"Major mode for viewing and editing AA."
(face-remap-add-relative 'default :family "MS PGothic" :height 120)
(setq line-spacing 0))
I don’t really know how to remove the red lines, I tried for almost an hour, but it looks alright still.

As for the Obsidian snippet
.aa {
letter-spacing: 0px;
display: block;
font-family: "MS PGothic", Mona;
font-size: 16px;
white-space: pre;
text-align: left;
line-height: 1.0;
word-wrap: break-word;
overflow-y: auto;
max-height: fit-content;
}
