For some reason I can not reproduce prince positions the footnote-marker in the margins of a page (see the borders in the image to get a hint). I tried to move it to the right with margin-left and padding-left and text-indent but the only thing that these solutions do is extend the footnote-marker area to the left instead of extending it to the right. It is as if the footnote-marker is not even placed within the footnote are.



The formatting I use is:

.fn {
    float: footnote;
    font-size: 8.0pt;
    line-height: 115%;
    padding-left: 6pt;
    text-indent: 0;
    border: 1pt solid #333
}

*::footnote-marker {
    font-weight: normal;
    margin: 0;
    text-indent: 0;
    border: 1pt solid #333;
}

Sorry for the question. After an afternoon of digging I found the passage on footnote-style-position and solved the issue on my own
