Breakpoint Upscaling in SJSS
SJSS employs an 'upscaling' approach for breakpoints:

Responsive Styling Example
Here's how to apply responsive styling in an Angular component using SJSS:
import { Component } from "@angular/core";
import { SjDirective } from "super-jss";
@Component({
standalone: true,
selector: 'app-responsive-demo',
template: `
<div [sj]="{
p: {
xs: '5px', // Padding for extra small screens
md: '10px', // Padding for medium screens
lg: '15px' // Padding for large screens
xl: '20px', // Padding for extra large screens
xxl: '25px' // Padding for extra extra large screens
},
bg: {
xs: '#6699ff', // Background color for extra small screens
md: '#99ff66', // Background color for medium screens
lg: '#ff6699' // Background color for large screens
}
}">
Responsive SJSS Component!
</div>
`
})
export class ResponsiveDemoComponent {}

Updating Breakpoints
To customize breakpoints, use the SjThemeService
in SJSS, which is particularly powerful and user-friendly due to its use of Angular signals. This approach minimizes boilerplate and simplifies state management.
import { Component } from "@angular/core";
import { SjDirective, SjThemeService } from "super-jss";
@Component({
standalone: true,
selector: 'app-responsive-demo',
template: `
<button (click)="updateBreakpoints()" [sj]="{ p: 1, bg: 'primary.main', color: 'primary.contrast', borderRadius: '4px', cursor: 'pointer' }">
Update Breakpoints
</button>
`
})
export class ResponsiveDemoComponent {
constructor(private sjTheme: SjThemeService) {}
updateBreakpoints(): void {
this.sjTheme.setTheme({
breakpoints: {
sm: 660, // optional: a new breakpoint assigned to sm
md: 980, // optional: a new breakpoint assigned to md
// add lg, xl, or xxl if needed.
}
});
}
}
