我有一些 mat-card，它们是 flexbox 项目。我希望卡片本身有点透明opacity: 0.8;。但里面的其余元素保持原样。

所以在我放置的所有其他项目中opacity: 1;，但这没有帮助。

.mat-card {
  opacity: 0.5;
}

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>
