Hi Lionel,
I just wanted to share an example of the above methods. For example, try pasting the following CSS into the bottom of your theme’s style.css file:
.tribe-mini-calendar-nav td,
.tribe-mini-calendar th {
background: #cc9900 !important;
border-color: #cc9900;
}
.tribe-mini-calendar td.tribe-events-has-events {
background: #cc9900 !important;
}
.tribe-mini-calendar-event .list-date .list-daynumber {
color: red !important;
}
See how this code affects the colors of things on your site; try removing bits of it temporarily to see the affect of each line. I hope this helps and serves as a good example for all further CSS tweaks you might want to make
Cheers,
George
