:''"Template:Leftdelimiter" and "Template:Leftdelimiter/doc" redirect to here.''<br />
<br />
This is for producing tall left-handed delimiters for multiline expressions (usually mathematical) in HTML, together with {{tl|rdelim}}, compatible with {{tl|math}}, as an alternative to LaTeX. Up to 5 lines are possible. The name "ldelim" is a shorthand for "left-handed delimiter".<br />
<br />
;This template uses {{tl|delimiter-es}}, and is used in {{tl|dsqbracket}} and {{tl|drndbracket}}.<br />
<br />
==Syntax==<br />
<br />
The template has the code:<br />
<br />
<code><nowiki>{{ldelim|a|b|sup=|sub=}}</nowiki></code><br />
<br />
containing two parameters:<br />
<br />
*the first parameter <code>a</code> is <br />
**'''square''' for square brackets [ ], <br />
**'''round''' for round brackets ( ),<br />
**'''vert''' for vertical bars | |,<br />
**'''doublevert''' for double vertical bars || ||,<br />
*the second parameter <code>b</code> is the number of lines for the expression, and equals one of the values '''2, 3, 4, 5'''.<br />
<br />
and two optional parameters:<br />
<br />
*'''sup''' for superscripts outside of the delimiter,<br />
*'''sub''' for subscripts outside of the delimiter.<br />
<br />
Without the superscript and subscript parameters, the <code>< sup ></code> or <code>< sub ></code> tags alone will not position the superscripts or subscripts correctly.<br />
