Why are there gaps in the workshop and project numbers?

I number the workshops, labs, theory sets, and projects in ascending order starting at 1, and only publish the work I complete. Many of the labs are reading-only, and I only include them if I make some notes or want to try one of the examples.

A few of the workshops are missing some steps, as when freeCodeCamp publishes updates, some of the steps I had previously completed are superseded and marked as incomplete, and so I finish and publish them. If I completed the original set of steps prior to 2022, when I started saving my work, then only the updated steps will be shown.

Why are you using CSS/JS before it's included in the lessons?

Sometimes it's functional, for instance when a picture would be larger than the screen if using only the default user-agent styling. But most of the time I prefer to add a little pizzazz, and it keeps me engaged in especially the earlier steps and workshops
