Misplaced Pages

Revision as of 08:26, 7 January 2015

This is the template sandbox page for Template:Div col (diff). See also the companion subpage for test cases.

This template uses Lua: Module:Check for unknown parameters (sandbox)

This template uses TemplateStyles: Template:Div col/styles.css (sandbox)

The template {{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. To prevent a section of a list being broken, the template {{No col break}} can be used.

Usage

Basic usage

{{div col}}<!-- default width is 30em -->
* a
* b
* c
* d
* e
* f
* g
* h
{{div col end}}

Produces:

• a
• b
• c
• d
• e
• f
• g
• h

Parameters

There are six parameters for this template:

|colwidth=

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 relative or absolute length unit, for instance, the em (about the width of the capital "M" of the displayed typeface), e.g., colwidth=20em.

|rules=yes

Adds vertical lines ("rules") between the columns if set to yes.

|gap=

Specifies the space between the content of adjacent columns, in any valid CSS width unit, e.g., gap=2em. The default spacing (set by browser) is 1em.

|class=

An HTML class, or multiple space-delimited classes, to apply to the columns.

|style=

CSS styling to apply to the columns.

|small=yes

Sets font size to 90%.

|content=

Content to apply to the columns. This parameter is effectively equivalent to {{columns-list}}, which is a pass-through for this template.

Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.

Limitation

Sub-lists

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

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

Produces:

• a
• b
• c
  • c.d
  • c.e
  • c.f
• g
• h

Turning off the break-inside: avoid-column; rule appears to help.

Chrome-based browsers can separate images from captions

In certain circumstances, Chrome-based browsers can separate images from their captions, placing the caption in the next column. This bug was reported in 2018 as T193163, and it appears to be a bug in Chromium, tracked as issue 40578413.

TemplateData

TemplateData for Div col

Redirects

• {{col div}}
• {{colbegin}} (but not {{col begin}} or {{col-begin}})
• {{cols}}
• {{div col start}}
• {{div col begin}}
• {{div-col}}
• {{palmares start}}

See also

• {{refbegin}} and {{refend}} (for columns in manual lists of references)

Column-generating template families

The templates listed here are not interchangeable. For example, using {{col-float}} with {{col-end}} instead of {{col-float-end}} would leave a <div>...</div> open, potentially harming any subsequent formatting.

Can template handle the basic wiki markup {| | || |- |} used to create tables? If not, special templates that produce these elements (such as {{(!}}, {{!}}, {{!!}}, {{!-}}, {{!)}})—or HTML tags (<table>...</table>, <tr>...</tr>, etc.)—need to be used instead.
