{{CSS3 multiple column layout}}

{{tl|Div col}} formats a list into columns that wrap properly and compatibly with portable computer devices, especially PAD operating systems and small screens. 

==Purpose==
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.
* The list content is either provided by the {{para|content}} parameter (which can be restrictive of what content is allowed; e.g., wiki markup such as the {{!}} character 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 ({{para|style}}).

{{tl|Div col}} can create multiple columns in [[web browser]]s which support the following [[CSS]] properties:
* ''column-width'' (for [[Cascading Style Sheets#CSS 3|CSS3]]-compliant browsers; see [http://www.w3.org/TR/css3-multicol/ CSS3 module: Multi-column layout])
 
By default, the template creates columns that are [[Em (typography)|30em]] wide.

==This template's parameters==
===Descriptions===
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). 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>. If no value is supplied, the template uses a default of 30em.
; {{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|small|yes}} : sets font size to 90%.
; {{para|content}} : content to apply to the columns.

===Example of "colwidth" parameter===
; Example with column width of 10em
<pre>
{{div col|colwidth=10em}}
* a
* b
* c
* d
* e
* f
* g
* h
{{div col end}}
</pre>
; produces:
{{Div col|colwidth=10em}}
* a
* b
* c
* d
* e
* f
* g
* h
{{Div col end}}

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

===Example 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}}

===Example of "small" parameter===
; Example showing how setting "small" parameter to "yes" produces smaller font size (90% of the size that would otherwise be displayed)
<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}}

===Example 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 parameters===
Parameters 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|colwidth=20em}}
* a
* b
* c
* d
* e
* f
* g
* h
{{div col end}}
</pre>
; produces:
{{Div col|colwidth=20em}}
* a
* b
* c
* d
* e
* f
* g
* h
{{Div col end}}

; Example with column width of 30em
<pre>
{{div col|colwidth=30em}}
* a
* b
* c
* d
* e
* f
* g
* h
{{div col end}}
</pre>
; produces:
{{Div col|colwidth=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|colwidth=10em}}
a
b
c
d
e
f
g
h
{{div col end}}
</pre>
; produces:
{{Div col|colwidth=10em}}
a
b
c
d
e
f
g
h
{{Div col end}}
