I use CSS to style layers in GeoServer. Some style parameters user gt-as a prefix. Like gt-label-follow-line or gt-label-repeat. What does gt stand for and where is the documentation for using those parameters?

1 Answer 1


I can't find any reference to gt-label-follow-line in the manual (or any where else). There are references to label-follow-line and label-repeat though.

  • Thanks for your effort Ian! I manage to find it in some very old docs. I'll just skip the -gt- part in the future.

  • probably best to ignore historic copies of the docs
