Theme Module

This module provides utility classes to compute UI customization based on content items.

Usecase

Allow a business user to customize the color scheme of a single page application by making modifications to a content item using the WCH admin UI. Without having to touch the source code of the deployed application.

Usage

The colors sub module exposes functions to compute color variations based on a (configured) base color. This can be used to automatically build a color palette.
The theme sub module computes CSS styles and CSS variables based on a RenderingContext.

Colors

A theme color palette typically consists of a set of base colors (such as primary or secondary) and derivations of these colors. Business users only want to customize the base colors, the variations can be computed.

Functions

the colorVariations method computes color variations for a base color by computing a set of darker and lighter colors. The result is provided as a mapping from CSS variable to color value.

Naming Scheme

The CSS variables are named using the following pattern: --${basename}-${method}-${level} where:

basename: logical name of the color in the scheme
method: variation, e.g. darken or lighten
level: percent value of the application of the method. A value darken-5 e.g. means that the base color has been darkened by 5%.

Theme Utilities

The utilities compute a full set of styles based on a RenderingContext.

Usage

Exposed functions:

`stylesFromRenderingContext': accepts a rendering context and returns a set of derived styles. @ibm-wch-sdk/theme > "colors/colors"
