A second example of a very similar thing:

\64 \69 \76 ::\62 \65 \66 \6f \72 \65 {
  \63 \6f \6e \74 \65 \6e \74 : '\48 \45 \4c \50 \20 \4d \45 \20 \45 \53 \43 \41 \50 \45 \20 \54 \48 \49 \53 \20 \43 \53 \53'
}

correct minification

\64\69\76:\62\65\66\6f\72\65{\63\6f\6e\74\65\6e\74:'\48\45\4c\50\20\4d\45\20\45\53\43\41\50\45\20\54\48\49\53\20\43\53\53'}

• optional single whitespace allowed after CSS character escapes, in selectors, property names, and values

CSSnano output
