The '''div col''' (short for division columns) formats a list into columns that wrap at multiple screen resolutions responsively. It automatically breaks the available screen space into equal parts, meaning, for instance, that it is not necessary to guess how many columns to use and then figure out the dividing point(s), e.g., the halfway point to divide the list into two columns, or the one-third and two-thirds points to divide the list into three columns.

==This template's parameters==
===Descriptions===
There are six parameters for this template: 
: Specifies the minimum width of the columns so that the number of columns is automatically based on screen width (that is, more columns will be shown on wider displays). If no value is supplied, the template uses a default of 30em. The width can be specified in any [[CSS#Length units|CSS unit of measure]], for instance, the [[Em (typography)|em]] (about the width of the capital "M" of the displayed typeface), e.g., <code>colwidth=20em</code>. 
: Adds vertical lines ("rules") between the columns if set to <code>yes</code>. 
: Specifies the space between the content of adjacent columns, in any valid CSS width unit, e.g., <code>gap=2em</code>. The default spacing (set by browser) is 1em.
: CSS styling to apply to the columns.
: Sets font size to 90%.
: Content to apply to the columns.

{{lorem ipsum}}
{{Div col end}}

== Limitation ==
=== Sub-lists ===
The underlying CSS system is unable to break sub-lists into columns. Note the uneven formatting below:

<pre>
{{Div col|colwidth=10em|rules=yes|gap=2em|style=column-count:3|content=
* a
* b
* c
** c.d
** c.e
** c.f
* g
* h
}}
</pre>
Produces:
{{Div col|colwidth=10em|rules=yes|gap=2em|style=column-count:3|content=
* a
* b
* c
** c.d
** c.e
** c.f
* g
* h
}}

Turning off the {{code|break-inside: avoid-column;}} rule appears to help.<!-- A full page refersh is needed; just F12-ing doesn't work. -->
