Enhancement: each month a slightly different color

[ms3056]

I'd like each month to be a slightly different "gray" color. Like striping in an excel data. For blocks with no info to report make odd months dark gray, and even months a slightly lighter dark gray, just so visibly it is a little easier to see at a glance.

it would be cool if each field had class like monthname, so we could set styles to the 12 month separately imho

I created a pull request to allow this exact behavior.

The code updates would require additional custom CSS code like the following

/* Alters the color of every second month */
.theme-dark .heatmap-calendar-boxes .month-feb.isEmpty,
.theme-dark .heatmap-calendar-boxes .month-apr.isEmpty,
.theme-dark .heatmap-calendar-boxes .month-jun.isEmpty,
.theme-dark .heatmap-calendar-boxes .month-aug.isEmpty,
.theme-dark .heatmap-calendar-boxes .month-oct.isEmpty,
.theme-dark .heatmap-calendar-boxes .month-dec.isEmpty {
	background: #414141;
	/* border: 1px solid #414141;*/
}

And lead to the following result:
