Summary
After a disaster of a request, Rean presents a coupon to Crow, who redeems it during their Free Day. Rean is used many times throughout 24 hours and quickly realizes what he’s gotten himself into.
It doesn't help that the coupon remains active when something comes up and he has to go to the Branch Campus.

Summary
Zemuria is low maintenance, the duty of their Gods a simple affair on the surface. As Flight itself, Crow spends most of his time with the birds under his domain, carefree as he can be. One sunny day, one of them wants to show him what they've found, and he follows them straight to a troubled God that makes him feel like he belongs somewhere for once in a long, long time.

mm whatcha say?: Changing Text On Hover for Multilingual Fics (A Download Friendly Workskin) by mackerel_cheese for Graverobbber, enbyguous, spearsofstarlight
Fandoms: No Fandom, Babel - R. F. Kuang

Summary
Do you want to have a nifty way to have multiple languages in a fic:
- Without making your readers scroll to the AN for a translation?
- Without the text and translation sitting side by side?
- And still make it look pretty when people download it into an EPUB or PDF format?
- Making it work with screenreaders? (Subject to varying screenreader capabilities)
Here is a solution for you. Come on babygirls, let's roll.
(This is a HTML tutorial but I'm lowkey flirting with you by calling you babygirl occasionally because I got bored while writing this.)
NEW UPDATE [20/3/2026]:
- Chapter 1: Sample Usage (Excerpt from a WIP in my drafts)
- A short character study about Griffin Harley from Babel (by R.F. Kuang). Utilizies 3 languages in multiple formats. You don't need to have read Babel to pick apart the code used.
- Chapter 2: Basic Tutorial (same as before)
- Chapter 3: FAQ (regarding customization and usage)

Summary
This is a live example of how an author can create linked footnotes in their work with only a little bit of HTML and no workskins required. This is best viewed by clicking "Entire Work". While I've included the actual coding in bold and italic once you click "Hide Creator's Style", there's a more detailed explanation here.
EDIT 6/28/17: The third chapter now shows how to use anchor links as an index/table of contents.
