Comment 5 for bug 940195

I just had a look at https://docs.djangoproject.com/en/1.3/ref/models/fields/ which uses sphinx and they seem to use something like:

#documentation a.headerlink {
    color: #c60f0f;
    font-size: 0.8em;
    padding: 0 4px 0 4px;
    text-decoration: none;
    visibility: hidden;
}
#documentation *:hover > a.headerlink {
    visibility: visible;
}

Would that be applicable?
