Build a Website

I have created an API for railways. Now I need a basic site which documents it's behaviour. I would like a tile like theme for the first page, which will document each function of my API. When the user clicks on tile then he goes to a different page which documents the function. I want a website roughly on the format of [login to view URL] but with a different theme. It will be a static simple website as I have to upload it on my own server.
