# Skabelon:Ldelim

"Template:Leftdelimiter" and "Template:Leftdelimiter/doc" redirect to here.

This is for producing tall left-handed delimiters for multiline expressions (usually mathematical) in HTML, together with {{rdelim}}, compatible with {{math}}, as an alternative to LaTeX. Up to 5 lines are possible. The name "ldelim" is a shorthand for "left-handed delimiter".

This template uses {{delimiter-es}}, and is used in {{dsqbracket}} and {{drndbracket}}.

## Syntaks

The template has the code:

`{{ldelim|a|b|sup=|sub=}}`

containing two parameters:

• the first parameter `a` is
• square for square brackets [ ],
• round for round brackets ( ),
• vert for vertical bars | |,
• doublevert for double vertical bars || ||,
• the second parameter `b` is the number of lines for the expression, and equals one of the values 2, 3, 4, 5.

and two optional parameters:

• sup for superscripts outside of the delimiter,
• sub for subscripts outside of the delimiter.

Without the superscript and subscript parameters, the `< sup >` or `< sub >` tags alone will not position the superscripts or subscripts correctly.
