Styling

Styling in your theme’s CSS stylesheet is recommended.

What is the class name?

I don’t know. Your site, isn’t it?

I have a related question and did not find an answer in the forum so far.
I did create additional styling in my theme’s style.css.
But cf7’s styles.css takes precedence over style.css. So how can I override the settings in styles.css?
For example: I want to remove the green border around the ‘success’-box.
