Ivo,
Casing is the border of the road, whereas the fill is the colour in the centre. You’ll see that these are two overlapping lines, with the casing slightly wider than the fill, such that just either edge shows through once the fill is drawn on top.

Hi, The nicest way I know is using some xslt from here: https://lists.berlios.de/pipermail/mapnik-users/2008-June/000986.html This produces a neatly formatted page listing all the layers, styles and rules with min/max zooms and mouse-overs with details of css parameters etc. I took a closer look now and it is really neat, but I don't understand this: minor-roads minor-roads-casing 5 000 1 000 ☡ ([highway] = 'secondary' or [highway] = 'secondary_link') and not ([tunnel]='yes' or [tunnel]='true') CSS: stroke: #a37b48 stroke-dasharray: stroke-linecap: round stroke-linejoin: round stroke-width: 17; minor-roads-fill 5 000 1 000 ☡ ([highway] = 'secondary' or [highway] = 'secondary_link') and not ([tunnel]='yes' or [tunnel]='true') CSS: stroke: #fdbf6f stroke-dasharray: stroke-linecap: round stroke-linejoin: round stroke-width: 14 Where is the difference between "fill" and the "casing"? The conditions are the same, aren't they? What do I miss here? Thanks Ivo
