Comment 4 for bug 1790189

This started in queens as a result of: https://review.openstack.org/#/c/339278/

Prior to that, the delete confirmation buttons used btn-primary (white on orange). Now the btn-danger is used (which is red). The problem is that 'a, a:link, a:visited' (color: orange) is overriding btn-danger's default color (white):

a, a:link, a:visited {
    color: #e95420;
}

.btn-danger {
    color: #fff; # this gets overridden - shows with striked-through
    background-color: #d9534f;
    border-color: #d43f3a;
}
