Good question. Yes, there are two ways you can modify the calendar’s CSS without touching core plugin files:
Use your theme’s CSS. You can override the calendar’s styles by dropping the them directly into your theme’s style.css file.
Use a separate stylesheet. You can also create a new folder in your theme’s directory called “tribe-events” and create a new file in there called tribe-events.css. Any styles you add there will override the calendar styles. There are more details on this method in our Themer’s Guide.
