I have ver 2.8.1 and i want to design it to my design needs.
Where do i change the main forums Table Variables?
The best approach is to use the theme boilerplate. You can read more about that here: https://docs.vanillaforums.com/developer/theme-boilerplate/
Although you are "forced" to learn a few things about some built tools, it has the advantage that styling special elements like e.g. tables becomes quite easy because the css source is split into files which gives you the opportunity to work exactly on the elements you need
Which located where?
Sounds pretty good on the paper, but in the reality the boiler theme is far away from to be perfect, and in my opinion there are alot things which should be fixed.. I mean, just watch the usage of dom sizes in the code of the boiler theme..
@prot0n it's not perfect, but I'd say it is the best start: it is well structured and if you assign your customizations on that you can benefit from fixes that this boilerplate still gets. As you can see on GitHub, the boilerplate is still worked on and improved.
Even if you prefer to base your theme on the Keystone theme the real base will be the boilerplate because the Keystone theme only enhances the boilerplate.
But if your point was something about css techniques, I'm the wrong person to talk to. I do not have enough knowledge about that 🙄
