# Template:Thinsp

The {{thinsp}} typographical template gives a thin space (also known as thin SP).

## Usage

{{thinsp}} or {{thinsp|htm}} (default)

or

{{thinsp|tex}}

where the parameter is taken from

• htm (default): to get the HTML+CSS Unicode character U+2009 (thin space, also known as thin SP), which is a thin variant (i.e. 1/6 em @opsp@@opsp@≈@opsp@@opsp@ 0.16667em) of the ordinary space U+0020 (space, also known as SP);
• tex: to get the TeX/LaTeX \, command, which yields a 3mu (mathematical units) space, i.e. 3/18 of a quad space (you may use this template within the {{math}} template, but not within the `[itex]...[/itex]` element).

It can be useful when, e.g. an ''italic'' character leans too close to the following [non-italic] character. Previously, `&nbsp;` (no-break space, U+00A0: 6 mu, no-break) was used as a workaround, but a thin space (3 mu) is better.

## Examples

The code (using the {{^}} template)

`{{math| ''a''{{^|''n''}} |&&}}`

yields (where the exponent is too close to the base)

 a n

while

`{{math| ''a''{{thinsp}}{{^|''n''}} |&&}}`

yields (where the exponent is now too far from the base)

 a  n

while

`{{math| ''a''{{^|{{thinsp}}''n''}} |&&}}`

yields (where the exponent is now just at the right distance from the base)

 a  n

## Example with HTML+CSS

The code

`The zeros of {{math| ''x''{{^|3}} {{op|+}} 2''x''{{^|2}} {{op|+}} 10''x'' {{op|-}} 20 {{=}} 0 |&}} are (...)`

yields

The zeros of
 x 3  +  2x 2  +  10x  −  20 = 0
are (...)

versus (e.g. to have more space before and after the = sign; not needed here, since the above was right)

`The zeros of {{math| ''x''{{^|3}} {{op|+}} 2''x''{{^|2}} {{op|+}} 10''x'' {{op|-}} 20 {{thinsp}}{{=}}{{thinsp}} 0 |&}} are (...)`

which yields

The zeros of
 x 3  +  2x 2  +  10x  −  20  =  0
are (...)

## Example with TeX

The code

`The zeros of {{math| ''x''{{^|3|tex}} {{op|+|tex}} 2''x''{{^|2|tex}} {{op|+|tex}} 10''x'' {{op|-|tex}} 20 {{=}} 0 |\$}} are (...)`

yields

The zeros of$\textstyle {x^{3}+2x^{2}+10x{\,}-{\,}20=0}$ are (...)

versus (e.g. to have more space before and after the = sign; really needed here, since the above was not right)

`The zeros of {{math| ''x''{{^|3|tex}} {{op|+|tex}} 2''x''{{^|2|tex}} {{op|+|tex}} 10''x'' {{op|-|tex}} 20 {{thinsp|tex}}{{=}}{{thinsp|tex}} 0 |\$}} are (...)`

which yields

The zeros of$\textstyle {x^{3}+2x^{2}+10x{\,}-{\,}20\,=\,0}$ are (...)
