Hi,
Glad to see such a helpful community:)
However, if you want to change all the primary buttons color allover the site https://prnt.sc/zoIEdp_wFTup then you can use the following generic code in your custom CSS to accomplish this task!
Changing the button and the border color:
.btn-primary, .sppb-btn-primary {
border-color: red !important;
background-color: violet !important;
}
Changing the button and the border color on hover:
.btn-primary:hover, .sppb-btn-primary:hover {
border-color: green !important;
background-color: yellow !important;
}
You can use your desired color in the above code:)
Note: Path towards custom CSS(Joomla 3): Extensions>Templates>Styles> Click on your current default template name then choose Template Options. Then find custom CSS within the custom code.
Best Regards
