There is a question worth answering before touching a PHP server after a critical security release: Which PHP process is serving the website? Not which PHP version was installed last month.

CSS Anchor Positioning Guide: Build Tooltips Without JavaScript

A tooltip should not be a difficult component. You have a button. You have a small box of information. The box needs to stay near the button. Simple.

Shopify Script Tags Are Ending: What Developers Need to Know

If your Shopify app still relies on ScriptTags to load JavaScript on a storefront, there is a migration you should already be working on.
