'Strata' is a free responsive HTML template perfect for a clean one page portfolio or even a personal site. The portfolio items open up using Poptrox - a popup gallery plugin for jQuery similar to the well known "Lightbox". I'd maybe tweak the intro button to "follow on twitter" instead of "Learn More". As much as Parallax Scrolling is being overdone/abused nowadays, there are good examples and in this case I quite like how the fixed left section moves slower than the right content when you scroll. I'm a big fan of HTML5 UP and been following the owner AJ on Twitter for a while now. We'll definitely be featuring more of HTML5 UP's free templates in the near future!
I am Strata, a super simple responsive site template freebie crafted by HTML5 UP. A simple, minimalist template that actually began life as an unused redesign of n33.co (my personal site). Includes a (configurable) parallax background effect, Poptrox-powered lightbox gallery, a bunch of pre-styled elements, and Sass sources for the Sass-inclined.
