Style Expressions

--- layout: example.html title: Style Expressions shortdesc: Demonstrates rule based styling. docs: > To style all features in a layer in the same way, you can use a symbolizer object with literal values as shown below for the land layer. In this case, all features have the same fill color. To style features in a layer based on a feature property, an expression can be provided in a symbolizer instead of literal values. In the first populated places layer below, the circle radius is based on the scalerank property. To conditionally apply different symbolizers based on a feature property, a list of rules can be provided. Each rule can have a filter expression. If this expression evaluates to true, the rule's style is applied. A rule with else: true applies if no previous rules have applied. The populated place labels are rendered with a list of rules given to the third layer. tags: "vector, style, expression" ---
