From orange to black:

Thanks in advance

And if i like to change other buttons how can i do that?

I am not good with css so the easiest way would be fine!

Never mind found it :

Code: Select all

.box.border1 .box-wrap,
.box.border2 .box-wrap {
  background: #fff;
  border: 2px solid rgba(0, 0, 0, 1);
  padding: 45px 45px 35px 45px;
}

Feel free to use!

Paste this in template manager -advance setting

I'm glad you could solve it out on your own
