This makes perfect sense for classes like &quot;.article51_footer_wrapper_margin50&quot;, look up the rule, and sure enough it looks like `.article51_footer_wrapper_margin50 { margin-bottom: 50px; }`<p>Seriously, just inline rules like that. If it is only applied in one specific place across the entire site either because it cannot or does not need to be made more general, then inlining it is easier to maintain and understand.
