Adding header links post vdom upgrade

[BenRoe (Ben)]

I use Flexbox to positioning the Links. Maybe it’s useful for someone.

.d-header .title {
  display: flex;
  align-items: center;
  justify-content: center;
  margin-top: 0;
}

#header-links {
    max-width: 50%;
    font-size: 1.2rem;
    margin-left: 30px;
    margin-top: 4px;
}
