Individual service hash "links" require offset due to ALA banner

[nickdos]

Each service on https://api.ala.org.au/ has a clickable link that uses a hashtag to allow that service to be bookmarked or linked to an email, et al. The links have the format #ws112. The ALA banner is now static and therefore the link action needs an offset so the service is not obscured by the banner.

See ALA WP site or biocache-hubs record page views which do this. E.g. something like:

:target::before {
  content:"";
  display:block;
  height:120px; /* fixed header height*/
  margin:-120px 0 0; /* negative fixed header height */
}

• [x] Fix CSS so selected service is visible

• [ ] For extra points, it would be good if a deep-link URL triggered the particular service to expand automatically, as if the user had clicked on that entry.

First task is now obsolete because the new ALA skin no longer always shows the header at top of the page.

Second task is still useful to do. @Rita-C ? E.g. https://api-test.ala.org.au/#ws72 should open/expand that entry
