So, as a total newbie, what would you recommend to start learning and do you know of any good resources? My guess would be: HTML5 CSS Vanilla JavaScript ES6 -... Please correct me if I'm wrong. Thanks!

So, it's still a bit unclear to me. I'm creating a website based on bootstrap but with a lot of custom css. As far as I can see, bootstrap uses !important quite often, so I guess I will have to use it as well?
