Bones is a WordPress Theme for Developers
Built around the HTML5 Boilerplate, Bones is a rock solid foundation to start any WordPress project. Keep what you need, remove what you don't. It's totally up to you.
Bones is not a Framework
Frameworks are great, but sometimes they make things more complicated than they need to be. Bones is bare and as minimalistic as possible. It's meant to be used as a per-project template, this means no Child Themes. Hooray!
Bones is Mobile-First & Responsive
Taking the Mobile-First approach is the way to go when building a responsive project. So Bones comes ready to roll with a unique LESS/Sass setup that serves minimal resources to smaller screens and scales up depending on your viewport. As anyone who's ever browsed on a 3G connection will tell you, it's a difference maker.
Bones comes loaded with LESS / Sass
Get started working with the future of CSS today. Using LESS or Sass can speed up your development time when used properly. Bones gets you started by giving you a great starting point.
Custom Post Types & Custom Dashboard Functions Preloaded
Bones makes it easy to add Custom Post Types by giving you a well documented example. It also includes functions to customize the admin area for your clients. These are totally optional though, so if you don't need them, delete them. No big deal.
Bones is totally Free
Yup. What's more, if you want to use Bones to create your own themes and sell them, go ahead. Bones is under the WTFPL. So download it and create something beautiful...or ugly. It's up to you really.
