i'm in engineering school and i'm very new in website development (not in my only did C language and algorithm) and i'd like to make one beautiful. By searching, i read that using Padrino/Sinatra could be nice. I installed it, but i didn't find a tutorial which regroup all. I'm so lost cause i find too much information but no good examples. In guides, i can't find anything on : how to design websites, how to make a menu...I think i really need examples or templates to start (a code to read).
Thanks
You can start from here: http://www.padrinorb.com/guides/blog-tutorial
It cover most of important concept of padrino and sinatra.
The best way I suggest is to look a bit into opensource websites, for example ours: https://github.com/padrino/padrino-web
On github there are thousands of websites built with padrino or sinatra, so you can find more less/higher complicated.
