Dear @theymos and @PowerGlove

What's your opinion about changing html/css tables with CSS Flexbox or Grid?
I am not a developer (but wanna become one), I created this demo when I was learning html/css and javascript.
Look at this: https://jaybates19.github.io/bitcointalk/

I rebuilt Bitcointalk's design with my own code. I used CSS grid instead of images (that Bitcointalk uses right now). I used a combination of Flexbox and CSS grid (mostly flexbox) instead of very old-fashioned HTML tables. Added a little button and with the help of small js, I implemented Dark and Light mode toggler.

With small modifications, the design is faster, responsive and also with dark mode. Is it easy for you guys to make small changes to Bitcointalk's current design? I don't know how SMF templates are written, so I don't know how easy or hard it is to modify but I'm asking you if that's possible and not too hard or time-consuming for you.
