Template:Colbegin/doc

Div col can be used to make a list into columns that wraps properly and compatibly with portble computer devices, esp. PAD operating systems and small screens. It automatically breaks each column into an equal space, meaning, for instance, it is not necessary to work out the halfway point, or the on-third & two-thirds points between two columns.
 * The list content is either provided by the content parameter (which can be restrictive of what content is allowed; e.g., wiki markup like | must somehow be escaped) or terminated with div col end. The 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 (yes), place vertical lines parameter ("rules") between the columns (rules) and to add other custom styling parameter (style).

Div col can create multiple columns in web browsers which support one of the following CSS properties:
 * column-count (for CSS3-compliant browsers; see CSS3 module: Multi-column layout)
 * -moz-column-count (for Mozilla/Gecko-based browsers such as Firefox)
 * -webkit-column-count (for WebKit-based browsers such as Safari and Google Chrome)

Usage
There are six parameters for this template and their usage is described below.
 * or first unnamed parameter : (Now deprecated, as colwidth below is better suited to flexible formatting for a variety of display screen sizes (from mobile phones, tablets, etc to widescreen cinema-style displays)) Specifies the number of columns (default 2).
 * colwidth or second unnamed parameter : 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. Specified in any CSS unit, for instance in em, about the width of a capital "M", e.g,
 * rules : Adds vertical lines ("rules") between the columns if set to  or some CSS styling (e.g.  ).
 * gap : Specifies the space between the content of adjacent columns. Specified in any CSS unit, e.g, . The default spacing (set by browser) is 1em.
 * style : CSS styling to apply to the columns.
 * content : content to apply to the columns.

Usage without parameters
Example with no parameters produces two columns as the default is two columns.


 * a
 * b
 * c
 * d
 * e
 * f
 * g
 * h


 * produces:


 * a
 * b
 * c
 * d
 * e
 * f
 * g
 * h

Usage with named parameters
When parameters are named in the template, they can be used in any order. Example: 


 * a
 * b
 * c
 * d
 * e
 * f
 * g
 * h

or


 * a
 * b
 * c
 * d
 * e
 * f
 * g
 * h


 * produces:


 * a
 * b
 * c
 * d
 * e
 * f
 * g
 * h

and exactly the same result below


 * a
 * b
 * c
 * d
 * e
 * f
 * g
 * h

Usage of parameters without naming the parameters
When parameters are not named then template considers first unnamed parameter to be "col", 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 "col" and "colwidth" could be unnamed but all other parameters (such as "rules", "gap", "style" and "small") must always be named in the template. Note the empty column for the "number of columns" between "Div col" and "10em".
 * Example with correct usage of unnamed parameters


 * a
 * b
 * c
 * d
 * e
 * f
 * g
 * h


 * produces


 * a
 * b
 * c
 * d
 * e
 * f
 * g
 * h

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.
 * Example with incorrect usage of unnamed parameters


 * a
 * b
 * c
 * d
 * e
 * f
 * g
 * h


 * produces (unnamed third, fourth and fifth parameters are ignored)


 * a
 * b
 * c
 * d
 * e
 * f
 * g
 * h

Usage of "col" parameter
Important tip: Use of now-deprecated "col" parameter is discouraged, leave it blank and instead use the "colwidth" parameter.
 * Example with 3 columns


 * a
 * b
 * c
 * d
 * e
 * f
 * g
 * h


 * produces:


 * a
 * b
 * c
 * d
 * e
 * f
 * g
 * h


 * Example with 4 columns


 * a
 * b
 * c
 * d
 * e
 * f
 * g
 * h


 * produces:


 * a
 * b
 * c
 * d
 * e
 * f
 * g
 * h

Usage of "colwidth" parameter
Important tip: Most wiki reviewers will reject the usage of previous parameter "col" and instead they prefer the use of this "colwidth" parameter i.e. it is strongly recommended to not use now-deprecated "col" parameter (please leave it blank) and instead use "colwidth" parameter. Note the empty column for the "number of columns" between "Div col" and "10em".
 * Example with column width of 10em


 * a
 * b
 * c
 * d
 * e
 * f
 * g
 * h


 * produces:


 * a
 * b
 * c
 * d
 * e
 * f
 * g
 * h


 * Example with column width of 20em


 * a
 * b
 * c
 * d
 * e
 * f
 * g
 * h


 * produces:


 * a
 * b
 * c
 * d
 * e
 * f
 * g
 * h


 * Example with column width of 30em


 * a
 * b
 * c
 * d
 * e
 * f
 * g
 * h


 * produces:


 * a
 * b
 * c
 * d
 * e
 * f
 * g
 * h

a b c d e f g h


 * produces:

a b c d e f g h

Usage of "rules" parameter

 * Example:


 * a
 * b
 * c
 * d
 * e
 * f
 * g
 * h


 * produces:


 * a
 * b
 * c
 * d
 * e
 * f
 * g
 * h

Usage of "gap" parameter

 * Example:


 * a
 * b
 * c
 * d
 * e
 * f
 * g
 * h


 * produces:


 * a
 * b
 * c
 * d
 * e
 * f
 * g
 * h

Usage of "small" parameter

 * Example showing how setting "small" parameter to "yes" produces smaller font size


 * a
 * b
 * c
 * d
 * e
 * f
 * g
 * h


 * produces:


 * a
 * b
 * c
 * d
 * e
 * f
