Yes! and no. The .css coding did work but did not correct for the missing features. And the styling looked almost identical to what I already had with the Crio theming. I was able to find the following code to highlight the current day (not sure why the theming overrode this in the first place).
#wp-calendar #today {
background:#FF1234;
color: #000000;
So now I’m onto tweaking the code to highlight dates with events and I can shut the door on my website building career! Thank you so much!!
