Alright, a fair enough example of making this rule confusing for someone who doesn't know SCSS to immediately intuit what element this rule is being applied to. But that still doesn't mean the CSS rule itself is obfuscated (anyone familiar with CSS will know this is applying a left margin of 5px to something). Far different from, say, something like:
wsze2NfA3sjX0eKampvYIZbUISElk+AhNvIs2iYnISsh/fP1MjvHODcrODXA68T5xgcMyDAwPwQ5DQ8WDAfNBAkLFxPYwwsfCwge
That is obfuscated CSS.
