Template:Ns/doc

Template:ns is designed to insert between 0 and 83 non-breaking (non-linewrapping) spaces rapidly according to the number assigned as its first (unnamed) parameter. If this parameter is not supplied or its value is not numeric, it inserts a default three non-breaking spaces.

Do not insert huge numbers of non-breaking spaces to achieve a particular article layout. The width of non-breaking spaces varies between platforms and fonts, and on mobile devices (over half of readers) they are likely to make content overflow the available width. Differences between fonts make them unsuitable for precisely matching the width of any other text; consider {{0}} to match the width of specific text.
