The calcite-base repository holds the variables and mixins used in Calcite Web. This includes resources regarding:
- motion (easing functions, transitions)
- type (font stacks, sizing, spacing mixins)
- reponsive design (breakpoints, respond-to mixins)
- utilities (clearfix, show/hide, etc)
- shadow (defined levels of depth)
- spacing (standardized vertical/horizontal spacing units)
If you use npm, installation is as easy as:
npm install @esri/calcite-base
You can also download the latest release manually.
In a Sass project, simply import calcite-base into your project and use the variables/mixins:
@import "./node_modules/@esri/calcite-base/dist/_index.scss";
.myClass {
@include font-size(-1);
}
If you only require certain mixins, you can import each section directly as well:
@import "./node_modules/@esri/calcite-base/dist/_type.scss";
.myClass {
@include avenir-light();
@include font-size(-1);
@include leading(2);
@include tracking(166);
@include word-spacing(200);
}
If you are using PostCSS (or standard CSS) there are a series of files which declare the variables utilizing custom properties (CSS Variables). You can use these along with something like the postcss-custom-properties library to utilize the base colors, styles, etc in your postcss project:
@import "./node_modules/@esri/calcite-base/dist/variables.css";
.myClass {
box-shadow: var(--shadow-1);
}
If you need some of these values and are using a CSS-in-JS approach, you can import them from the JavaScript file using ES6 modules:
import {avenirLight} from "@esri/calcite-base";
console.log(avenirLight); // '"Avenir Next", "Avenir", "Helvetica Neue", sans-serif'
Note when using partial imports like this, the hyphenated variables become camel case.
