Free Now Playing Display (via Last.FM) 2020-02-04

Downloaded the html file, added my API key, added to OBS as browser local file. Doesn't seem to work though. the words "now playing" appears and quickly slides downwards offscreen.
super easy compared to all the other ones ive tried, however there isn't a big explanation on how to customize it if you aren't familiar with CSS. How would one go on about removing the picture of the album and replacing it with text
The most elegant and simple way to show now playing on stream!
