I’ve released a collection of fixed header templates in plain HTML along with LESS files used to configure their styles. What’s neat about these is that you can take a style you like and tweak most of the style details from within the LESS.
Things from colors to transitions are configurable. Along with that are 11 demos that showcase how simply rearranging elements can create great looking combinations.
