CSS3 Multi-column Layouts
Schöner Überblick zu Multi-column Layouts mit CSS.
Essentially, the specification states that a multi-column element needs to have either a defined column width or column count. Browsers are supposed to render these elements similar to the way they render tables – but the content in a column layout is dynamically split into blocks.
At the moment, we’re not able to define certain properties about columns (like column-specific backgrounds), but it’s possible this might change.
