Sass 3.3 refactor

Sass 3.3 weather colors

$weather_bgs: (sun: #ffffcc, rain: #99ccff, snow: #eee, clouds: #ccc);

.weather-bg {
	@each $weather_name, $weather_color in $weather_bgs {
		&--#{$weather_name} {
			background: $weather_color;
		}
	}
}

Sass pre 3.3 weather colors

.weather-bg--sun {
	background: #ffffcc;
}

.weather-bg--rain {
	background: #99ccff;
}

.weather-bg--snow {
	background: #eee;
}

.weather-bg--clouds {
