Creating complex styles

Next, let's create some complex styling to visualize our main roads similar to the visualization we created in QGIS:

1. Create a new style. Name it accordingly, and limit it to our workspace.
2. Select the CSS option in the Format field.
3. Generate a line template, save the style, reopen it, and preview it on our roads layer.
4. Rewrite the rule as follows to show secondary roads, as they had a simple symbolizer:

        /* @title Important roads */        [fclass LIKE 'secondary%'] {         stroke: #8f9593;         stroke-width: 1;        }

5. It's time to create the complex line styles. In SLD, we would have to create multiple <FeatureTypeStyle> elements to have multiple lines drawn on each other. In CSS, however, we can define multiple styles in a single definition ...
