Thank you, both of you, for considering.
@hengiesel No problem. Below is a screenshot example of a card where I make use of text-indent. In poetic sections, each poetic line is a paragraph of its own (the <div> that was automatically created with the return key in previous versions). When a single poetic line is too long to display in the column, the continuation is displayed inset (I’m sure you’ve seen these before in various types of poetic or verse settings).
In the previous versions of Anki, I could type or paste the text and type returns after each line. Then I would edit the HTML for that note and simply wrap all the parts of a card that were poetry inside a single <div class='poetry'> that I would add myself. Adding that additional div was the only HTML editing I would need to do on a per card basis. The rest is handled by the card template, notably:
.poetry {
text-indent: -20px;
padding-left: 20px;
}
