Template:Multicol/doc

Usage
Multicol is used to start a multi-column section of a page. Between each block of column text insert Multicol-break and close the last column with Multicol-end. For example:

This text appears in the first column.

This text appears in the second column.

This text appears in the third column.

Provides this format:

This text appears in the first column.

This text appears in the second column.

This text appears in the third column.

You can have any number of columns. Each column will be the same width, equally dividing the available horizontal space. Each column has a small right margin (20 pixels), creating a "gutter" that prevents text in one column from touching text in the column to its right. See franl's user page for examples of how this template can be used.

Parameters
This template has two optional parameters: the overall width of the set of columns and the width of the gutter. The overall width of the set of columns can be an absolute value (e.g., 40em) or a percentage of the available page width (e.g., 50%). This parameter defaults to 100%. The second parameter is the "gutter" for the whole column set, which defaults to 20px.

The Multicol-break also takes an optional parameter for the gutter to its right, also defaulting to 20px.

For example, to create a 3-column section that is only 50% the width of the page, with 2-pixel right margins:

This text appears in the first column.

This text appears in the second column.

This text appears in the third column.

Provides this format:

This text appears in the first column.

This text appears in the second column.

This text appears in the third column.

The multi-column region is always positioned on the left side of the containing block. To change this, place the above Wikitext in a DIV block that has the CSS attribute text-align set to either center or right</tt>, like this:

Related templates
The templates Col-begin and friends do something similar to this template and its friends, but this template may be easier to use. Each of the following examples produce the same result (a 3-column table in which all columns have equal width):

Column 1

Column 2

Column 3

Column 1

Column 2

Column 3

It's simpler to add more columns to the Multicol example than to the Col-begin example, because in the latter case, all occurrences of Col-3 would need to be changed to Col-4.

These templates groups are not interchangeable. If you start with Multicol, but end with the plain col-end templates, then you'll have an unclosed   tag that can harm the formatting of the rest of the page. The problems created by mixing these templates is not easily visible for all users, so please don't assume that it's working properly just because it looks right for you.
