[unsupp0rted]

Vanilla JavaScript is supported natively by all web browsers now.

Nobody is suggesting using a 20mb framework to make a toggle switch work on a standalone page that isn’t a web app.

If you’re building a web app either way, then choosing between a screen full of CSS or a handful of lines of js is negligible.

For expanding sections, you should use native HTML elements when they do the job with less effort/code. You should use JS when they don’t.

What a strange statement. 'Vanilla' JS has been supported 'natively' in browsers since the late 90s.
