Our Commentary ​

This is the kind of article we love to see. Replacing JavaScript with native CSS and HTML for performance gains is always a win. It's a great reminder that the web platform is constantly evolving, and sometimes the best solution is to lean into what the browser can do natively. I'm always a fan of simpler, faster code.
