Where can I find Simple Calendar css file?

I found two:
https://[domain.tld]/wp-content/plugins/google-calendar-events/assets/css/default-calendar-grid.min.css
https://[domain.tld]/wp-content/plugins/google-calendar-events/assets/css/vendor/qtip.min.css

However…
It’s typically wiser (and a best practice) to override CSS styles with something like the Custom CSS module in the Jetpack plugin (https://www.ads-software.com/plugins/jetpack/) or try the wonderful My Custom CSS plugin (https://www.ads-software.com/plugins/my-custom-css/).

Yeah what @frutke mentioned is the best here. We run different scripts (regular and minified) depending on certain things so it would be best to just use something to override them rather than modifying the files directly. This also keeps you from losing those changes when an update is available.

I too cannot find css files within the WordPress plugin editor as I had before I updated to Simple Calendar 4.1.3 this morning. To my horror, my calendar was a mess so I quickly reverted my site back to the 2.3.2 version. I will definitely follow Frutke’s and Nick’s advice and override the css. I don’t know how that’s done but I’ll figure it out. All the same, what happened to the css? How can I even know what to override?
