No, there wasn’t ever any direct way to change the button colors, but here’s a snippet of CSS that you can put in the “Advanced Custom CSS” box on the “Custom CSS” tab in Exit Notifier settings to make them any color you want. The horrifying colors here are merely for demonstration purposes and I do not recommend you actually use this on anything, anywhere, ever as is:
.ja_btn_green,
.ja_btn_green:link,
.ja_btn_green:visited {
background: red;
border: 1px solid red;
color: white;
}
.ja_btn_green:hover {
background: pink;
color: red;
}
.ja_btn_red,
.ja_btn_red:link,
.ja_btn_red:visited {
background: orange;
color: purple;
}
.ja_btn_red:hover {
background: grey;
color: black;
}
Hope that helps!
