Bản mẫu:Mdash
—
![]() | Due to the discouragement of spaced em dashes by the Wikipedia Manual of Style, the usage of this template in articles should generally be avoided. There can be exceptions for some horizontal lists and navigation boxes, but even there the appropriateness of spaced em dashes is under dispute. For horizontal lists consider using {{·}} or {{ndash}} instead. For vertical lists simply use an en dash "– " directly. The en dash is the first item in the "Insert" section below the Wikipedia edit window. |
This is the mdash template, it looks like this " — ".
It works similarly to the html markup sequence " —
". That is, a non-breaking space, a long dash (known as an em dash) and a normal space.
{{—}} and {{emdash}} redirect here and can be used as alternative names for this template.
This template is used when you want something a lot stronger than a bold middot "·", a bullet "•" or a ndash "–".
Normal usage
[sửa mã nguồn]The recommended usage is to use no space before the template and one space after the template, like this:
[[Salt]]{{mdash}} [[Pepper]]
It will render one space on each side of the dash, like this:
If it line breaks then the line break will come after the dash, not before, like this:
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]]{{mdash}} [[Pepper]]{{mdash}} [[Curry]]{{mdash}} [[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:
And if it line breaks then the line break will come after one of the dashes, not before, like this:
But really, you should use bold middots "·" or ndashes "–" for such lists.
Incorrect usage
[sửa mã nguồn]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:
[[Salt]]{{mdash}}[[Pepper]] [[Salt]]{{mdash}} [[Pepper]]
Both of them will render exactly as before, with just one space on each side of the dash, like this:
And it will still only line break after the dash, like this:
But putting one or more spaces before the template will cause problems, like these examples:
[[Salt]] {{mdash}}[[Pepper]] [[Salt]] {{mdash}}[[Pepper]] [[Salt]] {{mdash}} [[Pepper]] [[Salt]] {{mdash}} [[Pepper]]
Then it will render with two spaces before the dash, and one after, like this:
And if it line breaks it might break before the dash, like this:
Technical details
[sửa mã nguồn]The space before the dash is a non-breaking space. That means it will not line break and will not collapse together with normal spaces that come before the template.
The space after the dash is a normal space. That means it wraps (allows line breaks) and it will collapse together with normal spaces that come after the template to form one single space.
