+This page let you test the rendering font-family declaration for monospaced fonts. TODO: add some references here :-)

+Erwin Dokter had the following explanation on <a href="https://bugzilla.wikimedia.org/33496">Bugzilla #33496</a>:
+</p>
+<blockquote>
+By default, a (Windows) browser has it's default font-sizes set at 16px for
+serif and sans-serif, and 13px for monospace. Except in IE, where you cannot
+set any font-sizes... it uses 16px for all fonts.
+<br/>
+Vector has a base font-size of 0.8em, and most browsers *correctly* scale down
+all fonts, including the monospace font, accordingly. So monospace is shown at
+0.8 x 13px = 10px (which is perceived as 'too small'). But when you assign any
+font besides just "monospace", those browsers will no longer treat it as
+monospace and use 0.8 x 16px = 13px instead.
