Tags vs fields to organize selected poetry collection

Following up, because this thread will come up when someone searches for poetry (or tiddlers with poems):

Poetry curators like @talha131 will surely be interested in this solution with thanks to pmario for recent postlink here to documentation at TiddlyWiki.com for getting line breaks in poetry to render naturally in TiddlyWiki. It’s simple enough that I’ll just paste it in below, tailored to poetry-specific use:

Assuming you have a poem tag on each poem tiddler, all you need is a tiddler tagged $:/tags/Stylesheet with the following:

[data-tags*="poem"] .tc-tiddler-body {
  word-break: normal; 
  word-wrap: break-word;
  white-space: pre-wrap;
}
