Hello everyone!

I play a game and i basically "host" a "game-server/world" so players can go into my website (http://kolvia.sytes.net) and create an account, watch characters, deaths, kills and more..
Anyways..

The layout as you can see on kolvia.sytes.net is the layout everyone starts with when getting the files for the first time.

http://shadowcores.twifysoft.net/ is the website I kinda want mine to look like, (they had the same layout as I have now in the beginning too) and they have used bootstrap. I have tried to make mine like that but I really cant.
Can anyone help me?
