WordPress is a wonderful blogging platform and content management system (we use it for Lifehacker). Its themes make it highly customisable, but creating a theme isn't easy if you don't know the ropes. Bones simplifies the process by providing you with basic code that's already optimised, functions across multiple browsers, and is easy to understand.
We've walked you through creating a WordPress theme before, but that approach isn't optimised for mobile browsers and doesn't offer the added features and simplicity of Bones. You don't have to just dive into the code, either. There's already a solid tutorial to help you get started. If you're looking to build a WordPress blog with your own custom theme, be sure to check it out.
