Property reference

Beneath views, Kumu uses a powerful CSS-based language to control the appearance of your maps.

If you're familiar with CSS, the advanced view editor will quickly become your best friend. The view builder only exposes a small set of the available properties. Being able to write views by hand is the only way to harness the full power of Kumu.

Note: We've adopted standard CSS properties and values wherever possible, straying where conventional values were irrelevant or misleading (eg display: map vs display: block), and adding properties specific to Kumu (such as bullseye-color).

There are just few more things you should know about the valid values listed below:

Where you see...	You can use...
color	Any CSS web color or hex color code
colorPalette	The name of one of our color palettes
'Field name'	The name of any of your fields, wrapped in single or double quotes
number or [number]	Any number
number number	Any two numbers separated by a space, e.g. 5 10
0	Only the number 0
0..1	Any number between 0 and 1
generic-family	The name of any CSS web safe font family
family-name	The name of any font family. freight-text-pro and proxima nova will always work, but other non-web-sage font families will only work if your reader has the font installed on their device.
icon-name	The name of any icon from the Font Awesome collection.
icon-style	solid or regular
https://...	Any URL. URLs starting with https are safest and will work best within Kumu.
string template	Any combination of letters, numbers, supported markdown (including raw HTML), or names of your fields wrapped in double curly brackets {{}}. Wrap the entire thing in double quotes. See our label templates guide for examples.
auto, background, bold, bottom, center, circle, clip, contain, cover, dashed, gradient, hidden, inherit, italic, manual, map, none, normal, off, rectangle, solid, square, url, visible, or wrap	That exact keyword

All values are unitless.
