Template:Block indent/doc

Usage
This template block-indents the value that is supplied to it. This is similar to block quotation, but it uses the HTML element, instead of semantically abusing the  element, which is only for block quotations. It is also preferred over semantically abusing a colon at the start of the line, which should be used only for description lists.

The default display differs from the block quotation template Quote in that it does not: Both templates support paragraph breaks using around second and subsequent paragraphs, as well as other HTML markup, and it is always safest to explicitly format with HTML rather than rely on MediaWiki's parser to do the right thing, as its behavior may be altered at any time by the developers.
 * introduce whitespace margins above or below the indented material (just add a blank line above and/or below manually); nor
 * indent from the right as well as the left (there is an optional parameter for this); nor
 * affect the font size of its contents; nor
 * (on mobile) bookend the block with large quotation marks.
 * support that other template's attribution parameters (since it isn't for quotations).
 * support plain blank-line paragraph breaks inside it.

right the value, also in, by which to indent the material from the right; defaults to   (use 7 to match the default left indentation)
