{{Ombox |type=notice |text=Columns are not supported by some older browsers, most notably Internet Explorer 9 and below and Opera 11.0 and below. See [[Template:Reflist#Browser support for columns|this page]] for more information.}}
{{CSS3 multiple column layout}}

{{tl|Div col}} can be used to make a list into columns that wrap properly and compatibly with portable computer devices, esp. PAD operating systems and small screens. It automatically breaks the available space into equal spaces, meaning, for instance, that it is not necessary to work out the halfway point, or the one-third & two-thirds points between two columns.
* The list content is either provided by the {{para|content}} parameter (which can be restrictive of what content is allowed; e.g., wiki markup like {{!}} must somehow be escaped) or terminated with {{tl|div col end}}. The {{tl|columns-list}} wrapper uses the parameter method for providing content (including its limitations).
* The template system (family) also offers parameter options to set a smaller (90%) font-size parameter ({{para|small|yes}}), place vertical lines parameter ("rules") between the columns ({{para|rules}}) and to add other custom styling parameter ({{para|style}}).

{{tl|Div col}} can create multiple columns in [[web browser]]s which support one of the following [[CSS]] properties:
* ''column-count'' (for [[Cascading Style Sheets#CSS 3|CSS3]]-compliant browsers; see [http://www.w3.org/TR/css3-multicol/ CSS3 module: Multi-column layout])
* ''-moz-column-count'' (for [[Mozilla application framework|Mozilla]]/[[Gecko (layout engine)|Gecko]]-based browsers such as [[Firefox]])
* ''-webkit-column-count'' (for [[WebKit]]-based browsers such as [[Safari (web browser)|Safari]] and [[Google Chrome]])

==Usage==
There are six parameters for this template and their usage is described below.
; {{para|colwidth}} : Specifies the minimum width of the columns and determines automatically the number of columns based on screen width (i.e. more columns will be shown on wider displays). Overrides ''cols''. Can be specified in any CSS unit, for instance in [[Em (typography)|em]], about the width of a capital "M", e.g, <code>colwidth=20em</code>
; {{para|rules}} : Adds vertical lines ("rules") between the columns if set to <code>yes</code> or some CSS styling (e.g. <code>1px dashed blue;</code>).
; {{para|gap}} : Specifies the space between the content of adjacent columns. Specified in any CSS unit, e.g, <code>gap=2em</code>. The default spacing (set by browser) is 1em.
; {{para|style}} : [[Cascading Style Sheets|CSS styling]] to apply to the columns.
; {{para|content}} : content to apply to the columns.
; {{s|{{para|cols}}}} {{nobold|or first unnamed parameter}} : ''(Now [[Deprecation|deprecated]], as ''colwidth'', above, is better suited to flexible formatting for a variety of display screen sizes (from mobile phones, tablets, etc to widescreen cinema-style displays))''<br/>Specifies the number of columns (default 2).

==Examples==

===Usage of "colwidth" parameter===
Important: The usage of the previous parameter "cols" is deprecated. It is strongly recommended to not use now-[[Deprecation|deprecated]] "cols" parameter (please leave it blank) and instead use "colwidth" parameter.
; Example with column width of 10em
<pre>
Note the empty column for the "number of columns" between "Div col" and "10em".
{{div col||10em}}
* a
* b
* c
* d
* e
* f
* g
* h
{{div col end}}
</pre>
; produces:
{{Div col||10em}}
* a
* b
* c
* d
* e
* f
* g
* h
{{Div col end}}



===Usage of "rules" parameter===
; Example:
<pre>
{{Div col|rules=yes}}
* a
* b
* c
* d
* e
* f
* g
* h
{{Div col end}}
</pre>
; produces:
{{Div col|rules=yes}}
* a
* b
* c
* d
* e
* f
* g
* h
{{Div col end}}


===Usage of "gap" parameter===
; Example:
<pre>
{{Div col|colwidth=10em|rules=yes|gap=2em}}
* a
* b
* c
* d
* e
* f
* g
* h
{{Div col end}}
</pre>
; produces:
{{Div col|colwidth=10em|rules=yes|gap=2em}}
* a
* b
* c
* d
* e
* f
* g
* h
{{Div col end}}


===Usage of "small" parameter===
; Example showing how setting "small" parameter to "yes" produces smaller font size
<pre>
{{Div col|small=yes}}
* a
* b
* c
* d
* e
* f
* g
* h
{{Div col end}}
</pre>
; produces:
{{Div col|small=yes}}
* a
* b
* c
* d
* e
* f
* g
* h
{{Div col end}}

===Usage of "content" parameter===
; Example showing how to provide "content" parameter without using {{tlx|Div col end}}
<pre>
{{Div col|colwidth=10em|content=
* a
* b
* c
* d
* e
* f
* g
* h
}}
</pre>
; produces:
{{Div col|colwidth=10em|content=
* a
* b
* c
* d
* e
* f
* g
* h
}}

===Usage with multiple named parameters===
When parameters are named in the template, they can be used in any order.
'''Example: '''
<pre>
{{Div col|colwidth=10em|rules=yes|gap=2em|small=yes}}
* a
* b
* c
* d
* e
* f
* g
* h
{{Div col end}}
</pre>
or
<pre>
{{Div col|rules=yes|gap=2em|small=yes|colwidth=10em}}
* a
* b
* c
* d
* e
* f
* g
* h
{{Div col end}}
</pre>
; produces:
{{Div col|colwidth=10em|rules=yes|gap=2em|small=yes}}
* a
* b
* c
* d
* e
* f
* g
* h
{{Div col end}}
and exactly the same result below
{{Div col|rules=yes|gap=2em|small=yes|colwidth=10em}}
* a
* b
* c
* d
* e
* f
* g
* h
{{Div col end}}


; Example with column width of 20em
<pre>
{{div col||20em}}
* a
* b
* c
* d
* e
* f
* g
* h
{{div col end}}
</pre>
; produces:
{{Div col||20em}}
* a
* b
* c
* d
* e
* f
* g
* h
{{Div col end}}

; Example with column width of 30em
<pre>
{{div col||30em}}
* a
* b
* c
* d
* e
* f
* g
* h
{{div col end}}
</pre>
; produces:
{{Div col||30em}}
* a
* b
* c
* d
* e
* f
* g
* h
{{Div col end}}

; Example of how this template behaves if no [[•|bullets]] (generated by asterisk mark) are used.
<pre>
{{div col||10em}}
a
b
c
d
e
f
g
h
{{div col end}}
</pre>
; produces:
{{Div col||10em}}
a
b
c
d
e
f
g
h
{{Div col end}}

==Deprecated usage==

===Usage without parameters===
''Usage of fixed column counts is deprecated, therefore this example should no longer be used as well.''
<s>Example with no parameters produces two columns as the default is two columns.
<pre>
{{Div col}}
* a
* b
* c
* d
* e
* f
* g
* h
{{Div col end}}
</pre>
; produces:
{{Div col}}
* a
* b
* c
* d
* e
* f
* g
* h
{{Div col end}}
</s>

===Usage of parameters without naming the parameters===
''Usage of fixed column counts is deprecated, therefore this example should no longer be used as well.''
When parameters are not named then template considers first unnamed parameter to be "cols", second unnamed parameter to be "colwidth", remaining unnamed parameters (e.g. third, fourth, fifth, etc. unnamed parameter) will be ignored by the template without providing an error message. The first and second parameter "cols" and "colwidth" could be unnamed but all other parameters (such as "rules", "gap", "style" and "small") must always be named in the template.
;Example with correct usage of unnamed parameters
Note the empty column for the "number of columns" between "Div col" and "10em".
<pre>
{{div col||10em|rules=yes|gap=2em|small=yes}}
* a
* b
* c
* d
* e
* f
* g
* h
{{div col end}}
</pre>
; produces
{{div col||10em|rules=yes|gap=2em|small=yes}}
* a
* b
* c
* d
* e
* f
* g
* h
{{Div col end}}


;Example with incorrect usage of unnamed parameters
Note that the unnamed third, fourth and fifth parameters will be ignored by the template. If used, then
third, fourth and fifth parameters must always be named.
<pre>
{{div col||10em|yes|2em|yes}}
* a
* b
* c
* d
* e
* f
* g
* h
{{div col end}}
</pre>
; produces (unnamed third, fourth and fifth parameters are ignored)
{{div col||10em|yes|2em|yes}}
* a
* b
* c
* d
* e
* f
* g
* h
{{Div col end}}

===Usage of "cols" parameter===
Important: Use of now-[[Deprecation|deprecated]] "cols" parameter is discouraged, leave it blank and instead use the "colwidth" parameter.
{{cot|deprecated example|bg=lightgray}}
; Example with 3 columns
<pre>
{{Div col|3}}
* a
* b
* c
* d
* e
* f
* g
* h
{{Div col end}}
</pre>
; produces:
{{Div col|3}}
* a
* b
* c
* d
* e
* f
* g
* h
{{Div col end}}

; Example with 4 columns
<pre>
{{Div col|4}}
* a
* b
* c
* d
* e
* f
* g
* h
{{Div col end}}
</pre>
; produces:
{{Div col|4}}
* a
* b
* c
* d
* e
* f
* g
* h
{{Div col end}}
