Available Red Background CSS

I had an issue on a website where all of the dates on the site where not getting the RED Background / Strike Through CSS applied. I thought It just wasn’t working on some months, but after some digging, most themes are conflicting with the “td.” Just add !important to the background color in the plug-in css to over-ride. Hope this helps anyone else having that problem.

.wp-availability-month table tbody td.wp-availability-booked {
font-weight: bold;
background-color: #CC0000 !important;
text-decoration: line-through;
color: white;
}
