Template:Spaced em dash/doc

This is the spaced em dash template, it looks like this "".

It works similarly to the HTML markup sequence " ". That is, a non-breaking space (which will not line break and will not collapse together with normal spaces that come before the template), a long dash (known as an em dash) and a normal space (will collapse together with normal spaces that come after the template).

This template is used when you want something stronger than a bold middot "&middot;" or a bullet "&bull;", and longer than a en dash "–". (An em dash is twice the width of an en dash.)

This template is not intended for normal use in articles. It is a helper template for writing other templates. For grammatical purposes, please use Em dash.

Normal usage
The recommended usage is to use no space before the template and one space after the template, like this: Salt Pepper It will render one space on each side of the dash, like this:
 * Salt &mdash; Pepper

If it line breaks then the line break will come after the dash, not before, like this:
 * Salt &mdash;
 * Pepper

For long dashed lists each list item can be put on its own line, with no spaces between each item and the template. Like this: Salt Pepper Curry Saffron

(It doesn't matter if there are no or some spaces at the end of the lines, after the templates.)

As before it will render one space on each side of the dashes, like this:
 * Salt &mdash; Pepper &mdash; Curry &mdash; Saffron

And if it line breaks then the line break will come after one of the dashes, not before, like this:
 * Salt &mdash; Pepper &mdash;
 * Curry &mdash; Saffron

Incorrect usage
If the template is used slightly wrong it will in some cases still behave well. For instance if there are no or several spaces after the template. Like these examples: SaltPepper Salt  Pepper

Both of them will render exactly as before, with just one space on each side of the dash, like this:
 * Salt &mdash; Pepper

And it will still only line break after the dash, like this:
 * Salt &mdash;
 * Pepper

But putting one or more spaces before the template will cause problems, like these examples: Salt Pepper Salt  Pepper Salt Pepper Salt     Pepper

Then it will render with two spaces before the dash, and one after, like this:
 * Salt &mdash; Pepper

And if it line breaks it might break before the dash, like this:
 * Salt
 * &mdash; Pepper
