I personally enjoy any sort of interactivity in tech articles. Things like sliders, inputs and buttons are great at keeping attention and can help make the subject easier to understand or illustrate things that can't easily be described in text.

Some examples:

https://ciechanow.ski/bicycle/

Although it's all very content dependent of course - FE development tends to lend itself a bit better to this sort of format.
