なんだこれ

私 < ちょっとこれやばくない
私 < 今回追加したJSが原因で死んでる
XXXX < これはあかんやつやな

XXXX < floatが予約語だから怒られてるっぽいw
XXXX < javascript - Compression issues with JQuery file in YUI Compressor - Stack Overflow

というわけで

#  変更前
float: 'left'

# 変更後
'float': 'left'

シングルクオート追加しました
JSの挙動としては問題ありません

YUI Compressorとは

JSやCSSを圧縮してデータ転送良を減らしてくれる
