AngularMaterialCssVars

You want to style your angular material dynamically with all the colors in the rainbow and don't really care about IE11 (support for css variables is required)? Look no further!

Check out the Demo!

Setup

• Install:

  npm i angular-material-css-vars -S
  

• If @angular/material is already configured remove @import '~@angular/material/theming'; from your main stylesheet file if present.
• Add this to your main stylesheet instead:

  @import '~angular-material-css-vars/main';
  @include initMaterialCssVars();
  

• Then use it like so:

  import {MaterialCssVarsService} from 'angular-material-css-vars';
  
  export class SomeComponentOrService {
    constructor(public materialCssVarsService: MaterialCssVarsService) {
      const hex = '#3f51b5';
      this.materialCssVarsService.setDarkTheme(true);
      this.materialCssVarsService.changePrimaryColor(hex);
      this.materialCssVarsService.changeAccentColor('#333');
    }
  }
  

Additional Features

• Auto or manually set contrast color via
  • switchToDarkContrastColor()
  • switchToLightContrastColor()
  • setAutoContrastEnabled(bool)
  • changeContrastColorThreshold(hueVal: HueValue)
• Helper to set all variables
  • setVariable(cssVarName: MaterialCssVariables, value: string)
  • You can use the MaterialCssVariables enum from here to make sure you get the variable name right.
• Rudimentary dark theme support via body class
  • setDarkTheme(isDark: boolean)

Utility

There are also several utility functions and mixins.

@import '~angular-material-css-vars/public-util';

.with-color {
  border-color: mat-css-primary-color(300);
}

.color-and-contrast {
  @include mat-css-color-and-contrast(300);
}

.with-bg {
  @include mat-css-bg(300);
}

Initialization Options

You can provide different options during initialization to change the body class used for the dark theme and to provide different default styles:

@mixin initMaterialCssVars(
  $default-theme: $css-vars-default-light-theme,
  $dark-theme-body-class: 'isDarkTheme',
  $default-theme-text: $css-vars-text
) {
  // ...
}

A full list of the theme map can be found here.
