(#qkqefka) @ullarah@txt.quisquiliae.com I check twtxt just now but it seems the way to go, the js code in the article feels a bit excessive to me.

A simple class added to the post that have more than X lines should be enough.

And by just nullifying the max-height with none or initial should do the job, or even better having a read-more class that add the max-height and show the button, it would be even cleaner.
