This reduction looks differently in Safari, Chrome and Firefox. But the website is only broken in Safari.

Correct. Adding the -webkit prefix to background-clip (-webkit-background-clip: text) makes the test case consistent with what we see on the web page.

rendering in safari, firefox, chrome

ok it took me a bit of time to reduce.
And the behavior is different on the 3 browsers.
This is working only with inline elements, not box elements. 


clipped green text on Safari
transparent on Firefox
Green square on Chrome

For Raul, 

Just remove these two properties in between 
    position: relative;
    top: 10px;
    -webkit-background-clip: text;
    background-clip: text;
    -webkit-text-fill-color: transparent;

from 

.bold-text1 {
    padding-left: 0px;
    background-color: #18143b;
    font-family: Poppins, sans-serif;
    color: #18143b;
    font-size: 15px;
    line-height: 25px;
    font-weight: 500;
}

And if you do not understand what that means, here is not exactly the right place, but you should ask to the person who created the website for you.

Just noticed zalan test reduction. It exhibits the same issues in the 3 browsers.

[Karl Dubost]

The implementations in both Firefox and Chrome have a couple of issues

Series of issues on Firefox
https://bugzilla.mozilla.org/show_bug.cgi?id=1656784

In chrome, background-clip: text is not yet supported.
https://bugs.chromium.org/p/chromium/issues/detail?id=1339290


Adding -webkit-background-clip: text

makes Firefox and Chrome behaving the same and Safari the outlier.
