Treesaver is a JavaScript framework for creating magazine-style layouts that dynamically adapt to a wide variety of browsers and devices. Designers use standards-compliant HTML and CSS for both content and design, no JavaScript programming is required.

The JavaScript is under 25K gzipped. And it works with most modern browsers, and degrades gracefully for older browsers. However, Treesaver is still quite immature. There are still a lot of bugs that need to be fixed.
