How to vertically align (bottom) images in passages? (Harlowe)

Hey all,

I'm working on a game called REFT in Twine 2.0 (Harlowe) as a final project for an experimental narratives course and have made a ton of progress with the mechanics. Now I'm trying to improve the aesthetics.

I use right and left arrow images to move forward and backward through passages, and these appear at the end of the text in each passage. A big part of the game is moving left and right through passages quickly, so I would like to make these arrow buttons stationary at the bottom of each passage. This would allow players to keep their cursor in one place and spam the buttons to quickly travel through passages.

I'm having trouble fixing these buttons in place at the bottom of the passages, though. I've tried adding align="bottom" (and other variations) inside the <img> code but this does nothing. I've also tried to create tables with <table><tr></tr></table> but these also don't show up. Any thoughts on how I can stick these buttons down there?

If you want, you can play the current prototype of REFT here to see what I'm working with.

Thanks!
