|
| The template '''{{tlf|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 {{tl|no col break}} can be used.

|
| |
|
| ==Usage==
| |
| ===Basic usage===
| |
| {{demo|sep=Produces:|<nowiki>{{div col}}<!-- default width is 30em -->
| |
| * a
| |
| * b
| |
| * c
| |
| * d
| |
| * e
| |
| * f
| |
| * g
| |
| * h
| |
| {{div col end}}</nowiki>}}
| |
|
| |
| ===Parameters===
| |
| There are six parameters for this template:
| |
| ; {{para|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 (typography)|em]] (about the width of the capital "M" of the displayed typeface), e.g., <code>colwidth=20em</code>.
| |
| ; {{para|rules|yes}}
| |
| : Adds vertical lines ("rules") between the columns if set to <code>yes</code>.
| |
| ; {{para|gap}}
| |
| : 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.
| |
| ; {{para|class}}
| |
| : An HTML class, or multiple space-delimited classes, to apply to the columns.
| |
| ; {{para|style}}
| |
| : CSS styling to apply to the columns.
| |
| ; {{para|small|yes}}
| |
| : Sets font size to 90%.
| |
| ; {{para|content}}
| |
| : Content to apply to the columns. This parameter is effectively equivalent to {{tl|columns-list}}, which is a pass-through for this template.
| |

| |
| * c
| |
| * d
| |
| * e
| |
| * f
| |
| * g
| |
| * h
| |
| }}</nowiki>}}
| |
|
| |
| ====Multiple parameters====
| |
| {{demo|sep=Produces:|<nowiki>{{div col|colwidth=10em|rules=yes|gap=2em|small=yes}}
| |
| * a
| |
| * b
| |
| * c
| |
| * d
| |
| * e
| |

| |
|
| |

| |

| |
|
| |
| ====Lorem ipsum====
| |
| {{demo|sep=Produces:|<nowiki>{{div col}} <!--Lorem ipsum -->
| |
| {{lorem ipsum}}
| |
| {{div col end}}</nowiki>}}
| |
|
| |
| == Limitation ==
| |
| === Sub-lists ===
| |
| The underlying CSS system is unable to break sub-lists into columns. Note the uneven formatting below:
| |
|
| |
| {{demo|sep=Produces:|<nowiki>{{div col|colwidth=10em|rules=yes|gap=2em|style=column-count:3|content=
| |
| * a
| |
| * b
| |
| * c
| |
| ** c.d
| |
| ** c.e
| |
| ** c.f
| |
| * g
| |
| * h
| |
| }}</nowiki>}}
| |
|
| |
| Turning off the {{code|break-inside: avoid-column;}} rule appears to help.<!-- A full page refresh is needed; just F12ing doesn't work. -->
| |
|
| |
| === 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 {{Phabricator|T193163}}, and it appears to be a bug in Chromium, [https://issues.chromium.org/issues/40578413 tracked as issue 40578413].
