You can consistently use a monospaced font with well-designed characters for coding (e.g., to distinguish clearly between <code>l</code>, <code>1</code>, and <code>I</code>, and between <code>O</code> and <code>0</code>, and between <code>-</code>, <code>−</code>, <code>–</code>, and <code>—</code>).

Add something like one of the code snippets below into your {{samp|[[Special:MyPage/common.css]]}} page, replacing {{kbd|"Roboto Mono"}} with whatever your preferred coding font is ([https://fonts.google.com/specimen/Roboto+Mono Roboto Mono] was picked as a freely-available coding font for this example).

If you don't want to manually add this code to your CSS page but would rather <code>@import</code> (transclude) it, see [[meta:User:SMcCandlish/codefont.css]] for quick instructions.

This code will do the following:
* Apply a consistent monospace font of your choice (and the fallback system-default {{samp|monospace}}, should that font go missing or not have characters you need) to all the normally monospaced HTML elements like {{tag|code|o}}, {{tag|pre|o}}, etc.
* Do the same for the classes used by {{tlx|mxt}} and other monospaced templates in the {{tlx|xt}} family
* Do the same for additional site-wide classes (as identified so far, e.g. <code>.monospaced</code>) that output as monospace.
* Make the three most frequently encountered editing fields also use this font stack: the main editing window, the edit summary line, and the search entry box.

If you know of an additional class to add here, please update this page or mention it on [[Template talk:Mxt/User CSS for a monospaced coding font|the talk page]].

<!--DO NOT ADD var TO THIS LIST! It must be able to inherit the font of surrounding text, because it is used outside code, as in "If <var>A</var> then <var>B</var>", and in math equations.-->

{{anchor|Cleanup efforts}}'''Cleanup efforts'''

If you'd like to help clean up instances of the {{tag|{{!mxt|tt}}}} element – which has not been valid HTML since the 1990s, and should usually be replaced with {{tag|{{mxt|code}}}} (this may vary by context) – you can add something like the following to your {{samp|common.css}} to make {{tag|{{!mxt|tt}}|o}} stick out like a sore thumb:

{{syntaxhighlight|lang=css|1=
/* Flag bad code for cleanup */
tt { color: DarkRed; background: Pink; }
}}

You can also do this with {{tag|font|o}}, {{tag|center|o}}, {{tag|strike|o}}, and other [[Wikipedia:HTML 5#Obsolete elements and attributes|deprecated elements]].  For CSS you can just import for this, see [[meta:User:SMcCandlish/lint.css]].<noinclude><!--
