居中 mat-tab-group

Question

我有 2 个标签，我希望它们位于中间。Angular Material 提供了mat-align-tabs="center"根本不起作用的简单类。我在互联网上搜索找到了 md 的解决方案，这是旧版本的 Material。令人惊讶的是，没有人没有遇到同样的问题。

HTML：

<mat-tab-group [(selectedIndex)]="selectedTabIndex"  mat-align-tabs="center">
    <mat-tab id="Wyszuk" label="Wyszukiwanie" *ngIf="!leadOffer.isSent">
      <app-offer-search-candidates [offerId]="leadOffer.id" [leadId]="leadId" [offer]="leadOffer"
        [candidatesToVerification]="candidatesToVerificationDataSource.data" [awaitingCandidates]="awaitingCandidatesDataSource.data"
        (addCandidatesToVerification)="onAddCandidatesToVerification($event)" (addAwaitingCandidates)="onAddAwaitingCandidates($event)"
        (addCandidatesToCart)="onAddCandidatesToCart($event)" (searchSave)="onSearchSave($event)">
      </app-offer-search-candidates>
    </mat-tab>

    <mat-tab label="Koszyk ofertowy">
      <app-offer-cart [dataSource]="candidatesDataSource" [searchModel]="searchModel" [readOnly]="leadOffer.isSent"
        [attachmentsDataSource]="attachmentsDataSource" (refresh)="onRefreshCandidates()" (removeCandidates)="onRemoveCandidatesFromCart($event)"
        (sendOffer)="onSendOffer($event)" (removeAllCandidates)="onRemoveAllCandidates()" (removeCart)="onRemoveCart()"
        (generateOffer)="onGenerateOffer()" (attachmentsLoaded)="onAttachmentsLoaded($event)" (removeAttachments)="onRemoveAttachments($event)"
        (generateCvs)="onGenerateCvs($event)" (updateProjectRole)="onUpdateProjectRole($event)" (updateSuggestedPrice)="onUpdateSuggestedPrice($event)"
        (candidateCvLoaded)="onCandidateOfferCvLoaded($event)">
      </app-offer-cart>
    </mat-tab>
</mat-tab-group>

Answer 1

应该是版本问题。在 Angular 6 中尝试过，不起作用。但是对于 Angular 7，它是：

https://stackblitz.com/edit/angular-mat-7-install-mat-tab-center

Angular 6：将此添加到您的全局样式表style.scss。

.mat-tab-labels {
    justify-content: center;
}

有关更多信息，请阅读此处。如果将其添加到 component.scss 中，它将被覆盖，在全局中不会。此外，您可以指定要应用此样式的组件。 https://stackblitz.com/edit/angular6-material-components-mat-tab-center
