HTML5 Boilerplate
A rock-solid default for HTML5 awesome. HTML5 Boilerplate is the professional badass's base HTML/CSS/JS template for a fast, robust and future-proof site. After more than three years in iterative development, you get the best of the best practices baked in: cross-browser normalization, performance optimizations, even optional features like cross-domain Ajax and Flash. A starter apache .htaccess config file hooks you the eff up with caching rules and preps your site to serve HTML5 video, use @font-face, and get your gzip zipple on. Boilerplate is not a framework, nor does it prescribe any philosophy of development, it's just got some tricks to get your project off the ground quickly and right-footed.
