We are happy to say “Hello World” from our new tool called: “Theme Builder for Angular Material”. You can visit it now at themes.angular-material.dev.
What is it?
Theme builder is a tool for Angular developers who are using Angular Material 18 in their project. This tool allows you to build, preview and export themes for Angular Material.
You can also share themes simply by using a unique link with your team of developers or designers.
How to use it?
First of all, create a project using Angular and Angular Material. You can jump to modifying define-theme mixin mixin if you have already created a project with custom theme.
ng new my-material-app –style scss –skip-tests –defaults
cd my-material-app
ng add @angular/material
And select answers as below:
? Set up global Angular Material typography styles? Yes
? Include the Angular animations module? Include and enable animations
Modifying the define-theme mixin
Take a look at src/styles.scss. Notice the usage of define-theme mixin:
$my-material-app-theme: mat.define-theme(
(
color: (
theme-type: light,
primary: mat.$azure-palette,
tertiary: mat.$blue-palette,
),
density: (
scale: 0,
),
)
);
We are going to make changes in above code to achieve customizations through CSS custom properties.
Add use-system-variables: true
Make changes in color and typography maps as below:
(
color: (
theme-type: light,
primary: mat.$azure-palette,
tertiary: mat.$blue-palette,
use-system-variables: true, // 👈 Added
),
typography: (
use-system-variables: true, // 👈 Added
),
density: (
scale: 0,
),
)
);
Modifying :root selector
Next, add below mixins in :root:
@include mat.all-component-themes($my-material-app-theme);
@include mat.system-level-colors($my-material-app-theme); // 👈 Added
@include mat.system-level-typography($my-material-app-theme); // 👈 Added
}
Generating theme from Theme Builder
Now go to themes.angular-material.dev, modify colors as per your need and copy the CSS variables.
Using CSS variables
Now, create a new file at src/styles/root.css and paste all content in it. Simply import that file through angular.json’s styles property! Or any other dynamic way, such that root.css file is rendered in correct order to reflect all –sys-* variables.
“styles”: [
“src/styles.scss”,
“src/styles/root.css”
],
}
