CSS Multi-Column Layout Generator
The CSS Multi-Column Layout module is one of the most underused layout tools in CSS. While flexbox and grid get most of the attention, multi-column offers something they don't: automatic text flow across columns, exactly like a newspaper or magazine. Our CSS Columns Generator gives you a visual, real-time editor to configure every multi-column property and copy production-ready code instantly.

What Properties Does This Tool Generate?
This generator covers the full CSS multi-column specification:
- column-count — specifies the exact number of columns the content should be divided into.
- column-gap — controls the space between columns (equivalent to
gap in grid/flex contexts).
- column-rule-width — the thickness of the line drawn between columns.
- column-rule-style — the line style: solid, dashed, dotted, double, groove, and more.
- column-rule-color — the color of the divider line.
- column-fill — whether columns should be balanced (
balance) or filled sequentially (auto).
- column-width — an optional minimum width per column, letting the browser calculate the count automatically.
- column-span — allows headings or elements to span across all columns.
How Does CSS Multi-Column Differ from Grid?
Grid layout is explicit — you define rows, columns, and place items in specific cells. Multi-column is implicit and flow-based — content simply pours into the next column when it runs out of vertical space. This makes multi-column ideal for long-form text content where you want newspaper-style reading, not a grid of independent boxes.
Use grid when you need precise placement of UI elements. Use multi-column when you want long text to flow naturally across columns.
When Should You Use CSS Columns?
CSS multi-column layout works best for:
- Long articles and blog posts — break up dense text into readable columns to improve readability on wide screens.
- Newspaper-style layouts — traditional editorial design with text flowing between columns.
- FAQ sections — questions and answers can flow naturally across columns.
- Lists and catalogs — product lists, footnotes, and reference tables benefit from columnar layout.
- Balanced sidebars — when you need balanced content on both sides of a page.
The column-rule Property Explained
The column-rule property is a shorthand for three sub-properties: column-rule-width, column-rule-style, and column-rule-color. It works exactly like the border shorthand, but the rule is drawn in the gap between columns — it doesn't take up any space.
The rule is only visible when column-rule-style is not none and column-rule-width is greater than 0. Our generator outputs the full shorthand: column-rule: 1px solid #444.
Understanding column-span
The column-span: all declaration is particularly powerful. When applied to an element inside a multi-column container, it causes that element to span across all columns — like a newspaper headline that stretches the full width before the story continues below in columns. Our tool includes a live toggle to preview this behavior with a heading element.
Browser Support and Compatibility
CSS multi-column has been supported in all major browsers for over a decade. Chrome, Firefox, Safari, and Edge all implement the specification fully. The generated CSS from this tool is production-ready with no vendor prefixes needed for modern browser targets.
