[FIXED] How do I divide cards into rows with every row having 4 cards

Issue

I want to make a site similar to E-commerce with cards and I am using Angular and MdBootstrap UI Kit.

Suppose I have 18 cards, I want 4 rows of 4 cards and last row should have 2 cards. My data for cards is coming from backend in json format.

But I am getting this Output.

What I desire is this.

Code I have currently

html:-

<div class="container">
  <div class="row" *ngFor='let row of grid'>
    <div class="col" *ngFor='let c of row'>
      <div style="margin: 10px">
        <mdb-card>
          <!--Card image-->
          <mdb-card-img src="https://mdbootstrap.com/img/Photos/Lightbox/Thumbnail/img%20(97).jpg" alt="Card image cap"></mdb-card-img>
          <!--Card content-->
          <mdb-card-body>

            <!--Title-->
            <mdb-card-title>
              <h4>{{c}}</h4>
            </mdb-card-title>

            <!--Text-->
            <mdb-card-text> Some quick example text to build on the card title and make up the bulk of the card's
              content.
            </mdb-card-text>

            <a href="#" mdbBtn color="primary" mdbWavesEffect>Button</a>
          </mdb-card-body>
        </mdb-card>
      </div>
    </div>
  </div>
</div>

ts:-

export class HomeComponent implements OnInit {
  cards: number;
  grid: number[][];
  constructor() {}

  ngOnInit() {
    this.cards = 18;
    this.gridgenerator();
  }

  gridgenerator(): number[][] {
    let last = this.cards % 4;
    let rows =
      this.cards % 4 === 0
        ? new Array(Math.floor(this.cards / 4))
        : new Array(Math.floor(this.cards / 4 + 1));
    this.grid = new Array(rows);
    for (let r = 0; r < rows.length; r++) {
      if (r === rows.length - 1) {
        this.grid[r] = new Array(last);
      } else {
        this.grid[r] = new Array(4);
      }
    }
    console.log(this.grid);

    return this.grid;
  }
}

Solution

Here is a working angular example, using only the flex properties.

The host element is a flex container and has the following css properties :

:host {
  display: flex;
  flex-wrap: wrap;
}

while the mdb-card is a flex item with the following properties :

mdb-card {
  margin: 10px;
  flex-basis: calc(25% - 2 * 10px); // 25% minus left and right margins.
}

No need of .row and .col elements.
