In 开发者_C百科CSS layouts what is the means of word "Faux column"?

It means "fake column". The French word faux translates roughly to false or fake.

The idea behind the faux columns technique was to allow developers to create columns that appear to stretch the full height of the viewport without resorting to a table-based layout.

Using a vertically-tiled background image to make a column appear as though it extends to the bottom of a page.
