Hello,

I have inspected the issue in detail and found that you have added the text in the wrong way.

If we trigger only one code then the CSS will affect all. So you need to break the text.

Please replace the code with the following:

.wholesale-btn::after {
content: "B2B zone";
color: red;
background-color: yellow;
padding: 5px;
}
.wholesale-btn::before {
content: "Wholesale \A " !important;
background-color: red;
padding: 5px;
}

And then you can set the values according to your needs.

Best Regards.
