Truncate text with ellipses but without cutting the last word

Question

I truncate my title with ellipsis by limiting it to 3 lines and 150 characters, but I have my last word which is cut. I looked for a solution without finding one that suits me.

In my html:

  <span class="w-100 data-set-card-title data-set-card-title-margin">{{card.resource_title}</span>

In my css:

font-size: 20px;
    font-weight: 400;
    color: $rudi-primary-color;
    display: -webkit-box;
    margin-bottom: 5px;
    -webkit-line-clamp: 3;
    -webkit-box-orient: vertical;
    overflow: hidden;
    hyphens: auto;
    min-height: 1.2em;

Result:

It has long been known that working with readable, meaningful text is distracting, and distracts from focusing on the layout itself. The advantage of the Lor... (last word is Lorem)

what i would like:

If you have any suggestions for me i'm taker

I found a solution using a pipe, for those who will have the same problem:

import {Pipe, PipeTransform} from '@angular/core';

@Pipe({
  name: 'truncateText'
})
export class TruncateTextPipe implements PipeTransform {

  transform(value: string, length: number): string {
    const biggestWord = 50;
    const elipses = "...";
    if (typeof value === "undefined") return value;
    if (value.length <= length) return value;
    //.. truncate to about correct lenght
    let truncatedText = value.slice(0, length + biggestWord);
    //.. now nibble ends till correct length
    while (truncatedText.length > length - elipses.length) {
      let lastSpace = truncatedText.lastIndexOf(" ");
      if (lastSpace === -1) break;
      truncatedText = truncatedText.slice(0, lastSpace).replace(/[!,.?;:]$/, '');
    }
    return truncatedText + elipses;
  }
}

-Template:

<span class="w-100 data-set-card-title data-set-card-title-margin" *ngIf="mediaSize.isMd">{{card.resource_title **| truncateText: 80**}}</span>
