No button for "Call to Action"

Hi what is the CSS code to hide the button for the "Call to Action Widget?

The site is locked - I need a more secure way to show you if you need to see it, but all I need is the CSS code for this and for my other posts. Thank you.

did you mean the CTA button in header area? if so, you don’t need css code to hide the button, just go to “appearance > customize > Header area > header text” you can remove the button text and button url.

OK done thank you!
