Getting started with Less CSS framework

I'm trying to cr开发者_StackOverflow社区eate a couple of static HTML pages for demo purpose. I decided Less 4 CSS framework

For now, I have two pages to demo:

1. Login page: contains a header and a login form at the center of the page.
2. Usual suspect page: header, footer, main content.
