At this point, it makes no sense to continue investing so much time to get so little done in terms of maintaining tommi.space… at least for the front end.

I have to study CSS frameworks and choose the one that suits me the most.

Starting using a framework would require refactoring all the visuals of the website, and it is probably going to take a lot of work and a long time. Nevertheless, it should be helpful in terms of performance, maintenance ease, simplicity.
