Can the forum site be fixed so that `code` snippets are always printed in fixed font?

Hi All -
this might go to @JAvila , or any administrator who could tinker with the behaviour of this forum - and I found no better category:
The problem is that
SELECT ' three_spaces_before'

(that is, using back-ticks before and after the string above ) will display with fixed font. But:

SELECT  '   three_spaces_before'

(that is, with the line: ```SQL before and the line ``` after)), will well colour-code the keywords and the literals , but still use proportional font, which makes a lot of what we want to show difficult to read.

Can anybody fix that for us?

Cheers and thanks for anything you can do ...
