Re: [Geoserver-users] Geoserver CSS Module

[Mark Cupitt]

Hi Jody, I am using the z-index as follows

In the polygon styling:
water  z-index: 50;
forest z-index: 40;
national parks z-index: 30;

This should ensure that river polys are drawn over the top of forests and
both drawn over the top of National Parks

The docs to not specify any magnitudes for it, and it appears to be a way
of grouping styles within a feature type style and ordering the
featuretypestyle so the rendering is as required.

For roads, I am using the following CSS

  stroke: #000000, #3CB371;
  stroke-width: 5.0px, 3.0px;

which forces two draws of the line. the first at #0000 5px, then drawn
again with #3CB371 at 3px to give the thinner line with a  black casing.

I do use z-index on the roads to ensure that motorways are drawn on top of
trunks, which are drawn on top of primary's, which are drawn on top of
secondary's, etc

Cheers

Mark
