You only need three things and no nodejs. NodeJS is mainly needed because many CLI and preprocessing/transforming tools are written in Javascript. If you don't use them, you don't need NodeJS. The three things: * HTML if you don't already know. * CSS Box Model, Flex and Grid. * Plain old JavaScript. For CSS topics above, there are pretty short videos on YouTube under an hour or so. If you feel like going sophisticated, encapsulate things as web components. They're mainstream now. These three above can DO EVERYTHING and everything else boils down to these anyways. Everything else is bloatware.
