How to create styled boxes on a webpage in where I can add graphs,gaugs,numbers?

I'm creating a 1 page dashboard that will run fullscreen on a monitor on which I want to display some graphs. I made the graphs already all I need now is a proper template for the page. I was thinking something like this

I really dig the look but I'm clueless on how to make something like this using presumably css/js. Especially the lines in the background and a titlebox.
