Angular 6 Material. How to make rubber for mat-sidenav-container? - angular6

Question

I have the responsive mat-sidenav which generated with Angular Material 6. Open/close button for navigation panel work excellent, but then navigation panel is open pannel obscure part of the content.
How to make the content part like a rubber:
<!--CONTENT-->
<main>
<router-outlet></router-outlet>
</main>
I mean when the navigation bar is closed then the content width is 100% of the page. But when navigation bar is opened then content compressed to 85% (My navigation bar have width: 15%)
This is template:
<mat-sidenav-container class="sidenav-container">
<mat-sidenav
mode="side"
#drawer
class="sidenav"
[(opened)]="isOpened"
fixedInViewport="true"
[attr.role]="(isHandset$ | async) ? 'dialog' : 'navigation'"
[mode]="(isHandset$ | async) ? 'over' : 'side'"
[opened]="(isHandset$ | async)"
>
<mat-nav-list>
<span
*ngFor="let link of links"
routerLinkActive="active"
>
<a mat-list-item [routerLink]="[link.url]">
{{link.name}}
</a>
</span>
<span style="position: absolute; bottom: 1px; width: 100%">
<a mat-list-item class="waves-effect waves-orange" (click)="logout($event)">
Выйти
</a>
</span>
</mat-nav-list>
</mat-sidenav>
<mat-sidenav-content>
<mat-toolbar color="primary">
<button mat-icon-button (click)="drawer.toggle()">
<mat-icon>menu</mat-icon>
</button>
<span style="margin-left: 45%">Oasis Bot Manager</span>
</mat-toolbar>
</mat-sidenav-content>
</mat-sidenav-container>
<!--CONTENT-->
<main [ngStyle]="{'width': isOpened ? '85%' : '100%'}">
<router-outlet></router-outlet>
</main>
TypeScript side:
export class SiteLayoutComponent {
links = [
{url: '/vds_list', name: 'Статистика'},
{url: '/profile', name: 'Личный кабинет'}
];
isOpened;
isHandset$: Observable<boolean> = this.breakpointObserver.observe(Breakpoints.Handset)
.pipe(
map(result => result.matches)
);
constructor(private breakpointObserver: BreakpointObserver,
private auth: AuthService,
private router: Router) {
}
logout(event: Event) {
event.preventDefault();
this.auth.logout();
this.router.navigate(['/login']);
}
}
I'm trying bind width of content through [ngStyle] to [(opened)]="isOpened" state of mat-sidenav.
But not work. How to resolve this situation?

Your content area needs to be inside mat-sidenav-container below the toolbar:
<mat-sidenav-container class="sidenav-container">
<mat-sidenav
mode="side"
#drawer
class="sidenav"
[(opened)]="isOpened"
fixedInViewport="true"
[attr.role]="(isHandset$ | async) ? 'dialog' : 'navigation'"
[mode]="(isHandset$ | async) ? 'over' : 'side'"
[opened]="(isHandset$ | async)"
>
<mat-nav-list>
<span
*ngFor="let link of links"
routerLinkActive="active"
>
<a mat-list-item [routerLink]="[link.url]">
{{link.name}}
</a>
</span>
<span style="position: absolute; bottom: 1px; width: 100%">
<a mat-list-item class="waves-effect waves-orange" (click)="logout($event)">
Выйти
</a>
</span>
</mat-nav-list>
</mat-sidenav>
<mat-sidenav-content style="display:flex; flex-direction:column;">
<mat-toolbar color="primary">
<button mat-icon-button (click)="drawer.toggle()">
<mat-icon>menu</mat-icon>
</button>
<span style="margin-left: 45%">Oasis Bot Manager</span>
</mat-toolbar>
<!--CONTENT-->
<main>
<router-outlet></router-outlet>
</main>
</mat-sidenav-content>
</mat-sidenav-container>
