我有mat-sidenav使用 Angular Material 6 生成的响应。导航面板的打开/关闭按钮效果很好，但是导航面板是打开的面板模糊了部分内容。
如何使内容部分像橡皮一样：
<!--CONTENT-->
<main>
<router-outlet></router-outlet>
</main>
我的意思是当导航栏关闭时，内容宽度是页面的 100%。但是当导航栏打开时内容压缩到 85%（我的导航栏有width: 15%）
这是模板：
<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($event)">
Выйти
</a>
</span>
</mat-nav-list>
</mat-sidenav>
<mat-sidenav-content>
<mat-toolbar color="primary">
<button mat-icon-button (click)="drawer.toggle()">
<mat-icon>menu</mat-icon>
</button>
<span style="margin-left: 45%">Oasis Bot Manager</span>
</mat-toolbar>
</mat-sidenav-content>
</mat-sidenav-container>
<!--CONTENT-->
<main [ngStyle]="{'width': isOpened ? '85%' : '100%'}">
<router-outlet></router-outlet>
</main>
打字稿方面：
export class SiteLayoutComponent {
links = [
{url: '/vds_list', name: 'Статистика'},
{url: '/profile', name: 'Личный кабинет'}
];
isOpened;
isHandset$: 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']);
}
}
我正在尝试将width内容绑定[ngStyle]到[(opened)]="isOpened".mat-sidenav
但不行。如何解决这种情况？
