Simple Horizontal Masonry

horizontal.masonry.js

/**
 * Builds a horizontal masonry in whats possbily (i haven't researched
 * the techniques) a crude manner.
 * Fits elements into columns if there is room and sets the width of
 * the container element to contain all the columns.
 * 
 * Known Issues:
 * - Does not do anything clever for elements where height exceeds 
 * window height (probably just gets chopped off if overflow: hidden)
 * - All elements are expected to be the column width
 * - Column count is wrong (misses off last one), added manual widths for now
 *
 * UPDATE 05/07/11 : Added gutterHeight
 * UPDATE 05/07/11 : Fixed issue of first item on some columns not having a gutter below it
 *

can you provide some demo?
