Скачать или смотреть CSS Trigonometry is surprisingly useful

I'm working on a course that covers Sass in real world situations, and a lot more: https://beyondcss.dev

Trigonometry is here in CSS with sin(), cos(), and tan(), as well as a few others. I kept seeing a lot of people excited for these, but I didn't really get why for a long time, but I found a good use case for sin() and cos() and wanted to share it in this video.

I also take a look at how we can step things up with a Sass/SCSS loop and a little bit more than that as well.
