Custom Theme supported

This is an example of custom-theme that can be applied for instance via an ng-class directive to the container of the library. In this way you are redefine some variables that are defined and used inside the library and it is easier to override some properties

.custom-theme {
    --ngx-timeline-icon: black;
    --ngx-timeline-period-inner-container: black;
    --ngx-timeline-line-background: black;
}

Examples with contexts of custom templates

  <ng-template #periodCustomTemplate let-period=period let-index=index let-event=event>
    <div [ngClass]="{'transparent first-line': !index}" class="line"></div>
    <div class="period-container">
      <p>
        {{index}} - {{period | json}}
      </p>
    </div>
    <div class="line"></div>
  </ng-template>

  <ng-template #centerIconCustomTemplate let-index=index let-event=event>
    <div class="icon-container">
      <img src="assets/image.png">
    </div>
  </ng-template>

  <ng-template #innerEventCustomTemplate let-event=event>
    <div class="event" (click)="handleClick(event)">
      {{event | json}}
    </div>
  </ng-template>
