Angular Hide With Button

Your HTML

<div class="yourCssClass" *ngIf="this.isButtonVisible" (click)="this.isButtonVisible = false">
...
</div>

Your TypeScript

export class AppComponent {
   private isButtonVisible = true;
}

This should do the job. *ngIf automatically hides the element, if the condition evaluates false, so setting the variable to false is sufficient.

The problem I see here is, that you don't control the visibility at any point. Using [ngClass] to add a specific class, if a condition is met, or *ngIf is helpful, whenever you try to change elements on user interaction.

For more information on [ngClass], you can read about its usage here: https://angular.io/api/common/NgClass

You can read about *ngIf here: https://angular.io/api/common/NgIf

Especially the "Common Use" part should be interesting for you.

Edit: Reading your comment below it seems you did not notice what [hidden] and (click) actually do. [hidden] controls the visibility of the element, usually dependent on a certain condition. (click) however is a quick way to bind a Click-Event to your element.

Using both of those tools enables to hide an element, by changing a variable, if a user clicks on your element (the new value of the variable may be assigned by a function called by (click) or inline, as demonstrated in the example code).

Edit2: Yep, you meant Angular2/4 ;) So this should do the job.

Here is how you can achieve that:

In your component.html:

<a type="button" class="more-styles" 
   [hidden]="!inboundClick" 
   (click)="inboundClick = !inboundClick" 
   [routerLink]="['/inbound']" href="">
</a>

<a type="button" class="more-styles" 
   [hidden]="!outboundClick " 
   (click)="outboundClick = !outboundClick " 
   [routerLink]="['/outbound']" href="">
</a>

... and in your AppComponent:

export class AppComponent {
    inboundClick = true;
    outboundClick = true;
}
