How I built a ruler page without Code

I built this page called Simple Online Ruler using just ChatGPT/Codex.

I just asked it to create an online ruler page with a ruler, and some info on how it works, how it is used and it generated it without any bugs. It was created with just one prompt.

It took inspiration from existing sites, added relevant pages which were present in the existing sites.

So, far I am very happy with Codex doing all these without much work.

And I have deployed it on Cloudflare Workers.
