javascript – How to change ant-design Tabs default border color

I can’t change the default border color of antd Tabs.

Tabs with Default border:
tabs-default-color

What I want is this:
tabs-black-border

somehow, I was able to achieve this but it’s not responsive, it takes more time.
It messed up with the mobile screen, etc.

 .ant-tabs-content-holder:after {
    padding: 0;
    margin: 0;
    display: block;
    content: '';
    height: 1.1px;
    position: absolute;
    top: -1px;

    left:  '0%';
    width: 24.8%;
    background-color: white;
  }

not-responsive-small-screen

How to achieve this? Any idea? is there any ant design vars for tabs border that I can use with webpack or less? antd docs has style props for it? I will appreciate your help.
