Builtin Namespaces#
The following namespaces provide access to common constants such as special keys or named colors.
Colors
#
Use the colors namespace to select colors by their name. For example you can use Colors.aquamarine
or Colors.bisque
.
The entire list of names is very long. You can find a complete list in the CSS Specification.
These functions are available both in the global scope, and in the Colors
namespace.
rgb(int, int, int) -> color
,rgba(int, int, int, float) -> color
Return the color as in CSS. Like in CSS, these two functions are actually aliases that can take three or four parameters.
The first 3 parameters can be either number between 0 and 255, or a percentage with a %
unit.
The fourth value, if present, is an alpha value between 0 and 1.
Unlike in CSS, the commas are mandatory.
