A few months ago, I did not have the skills to create simple web based tools, I just didn’t know where to start. But now, things have changed and I understand these things better, and I am not even actively trying to learn.
For this the generator, I used a minimal CSS framework called PicoCSS that I discovered only a few weeks ago. And the idea to create this came from a simple Google Sheets script that wrote a while ago. Yes, this is not something groundbreaking, but I am seeing it as a start only and it will definitely help me in building more complex tools, some day.
In fact, I have now learned a static site generator technology called 11ty and have used the tech in building the QR code generator.
And just to clarify, I do use ChatGPT whenever I am stuck or need ideas on how to do something. I do not avoid it.
