Hello,
If your theme doesn’t offer an option to change the button color, you can change it by adding custom CSS like below to Appearance > Customize > Custom CSS:
a.button:hover {background-color: #000000;}
If you’d like to learn more about CSS, I highly recommend using the free tutorials at w3schools. Here, you can find the basics of selectors (how to target the right element on the page), and properties (how to change the element on the page).
Hi @croydonweb
We’ve not heard back from you in a while, so I’m marking this thread as resolved. If you have further questions, please feel free to open a new topic.
