I generally avoid flex for simple stuff (i like weird browsers), but for more complex layouts it should certainly be used.

eventually they get collapsed into a view more

I actually nest everything in <p>s

You literally just have to give it a width and add margin: 0 auto;

Try using luarocks with luajit.

I use zip files, Dropbox and a load of fragile shell scripts.

pro tip:

"ba" + 0/0 + "a"
