This template is used on many pages and changes may be widely noticed. Test changes in the template's /sandbox or /testcases subpages, or in your own user subpage. Consider discussing changes on the talk page before implementing them.

This template uses Lua:

Module:Indent

Shortcut

{{i}}

The template {{indent}} performs a newline and indents by a specified number of spaces. However, the spaces are not all the same size, but rather a mixture of en-size & em-size spaces that have been tested to work on a wide range of browsers. (To skip by n equal-size spaces, instead use {{in5|n}}, which puts all as the standard-size non-breaking space and does not force a newline.)

Usage

The indentation spacing generated by Template:Indent will match the alignment of a colon-shift : by using {{indent|5}}. To match ::, use {{indent|10}}.

Note: This may vary depending on your browser.

Usage: {{indent|# of spaces}}

Indents up to 30 spaces. (use {{in5|n}} to skip up to 50 spaces)
Indent differs from {{spaces}} only in that it automatically begins a wrapped-newline, then spaces over n spaces, whereas {{spaces}} spaces over n in the same (current) line.

Examples

The following are detailed examples, also comparing to the equivalent indentation generated if a colon-shift : were used instead.

Example 1 – *Indenting by 5:*
Markup	Some text.{{indent\|5}}Some more text.
Renders as	Some text. Some more text.

Markup

: Line of colon-shifted text.
{{indent|5}}Line of indent-5-shifted text.
<br>      Line of br-6-nbsp-shifted text.
<br>     Line of br-5-nbsp-shifted text.
<br>     Line of br-5-nbsp-true-shifted text.
:: Line of 2-colon-shifted text.
{{spaces|10}}Line of space-10-shifted text.

Renders as

: Line of colon-shifted text.

Line of indent-5-shifted text.
Line of br-6-nbsp-shifted text.
Line of br-5-nbsp-shifted text.
Line of br-5-nbsp-true-shifted text.

Line of 2-colon-shifted text.

Line of space-10-shifted text.

Note that if the prior line is already colon-shifted text, then using "{{indent|5}}" generates a blank line first, so instead, use "{{spaces|5}}" (or such) after a colon-shifted line.

Analysis of uneven spacing

As computers optimize code, they occasionally risk displaying unsavory results after condensing monotonous strings of characters (such as spaces). Thus, many templates around Wiki choose to avoid this hurdle by alternating different types of spaces (with the intention of displaying no differently than regular spaces).

Spaces come in two main size varieties: em spaces and en spaces. Em spaces are generally defined as the width of one character, and en spaces exactly half that size. However, there is no requirement that browsers must conform to this standard, and so templates that code in en spaces may not display uniformly across all browsers. Neither {{indent}} nor {{spaces}} use true space-size (that is, em-size spaces), but rather mix en and em spaces, whereas {{in5|n}} avoids en spaces altogether and will actually skip n count of spaces, as if inserting n repetitions of an em space. This is done by alternating em spaces with an em-size non-breaking  —by definition, it must be the same—in order to skip a wide area.
