Types¶

A Mapbox style contains values of various types, most commonly as values for the style properties of a layer.

Color¶

Colors are written as JSON strings in a variety of permitted formats: HTML-style hex values, rgb, rgba, hsl, and hsla. Predefined HTML colors names, like yellow and blue, are also permitted.

{
  "line-color": "#ff0",
  "line-color": "#ffff00",
  "line-color": "rgb(255, 255, 0)",
  "line-color": "rgba(255, 255, 0, 1)",
  "line-color": "hsl(100, 50%, 50%)",
  "line-color": "hsla(100, 50%, 50%, 1)",
  "line-color": "yellow"
}

Especially of note is the support for hsl, which can be easier to reason about than rgb().

Enum¶

One of a fixed list of string values. Use quotes around values.

{
  "text-transform": "uppercase"
}

String¶

A string is basically just text. In Mapbox styles, you’re going to put it in quotes. Strings can be anything, though pay attention to the case of text-field - it actually will refer to features, which you refer to by putting them in curly braces, as seen in the example below.

{
  "text-field": "{MY_FIELD}"
}

Boolean¶

Boolean means yes or no, so it accepts the values true or false.

{
  "fill-enabled": true
}

Number¶

A number value, often an integer or floating point (decimal number). Written without quotes.

{
  "text-size": 24
}

Array¶

Arrays are comma-separated lists of one or more numbers in a specific order. For example, they’re used in line dash arrays, in which the numbers specify intervals of line, break, and line again.

{
  "line-dasharray": [2, 4]
}
