Keeping 3 cards in same row using grid

Question

I created a list of cards using grid. The CSS:

body {
  padding: 40px 0;
}

.grid {
  display: grid;
  grid-template-columns: repeat(auto-fill, minmax(280px, 1fr));
  grid-gap: 20px;
  align-items: stretch;
}

.grid > article {
  border: 1px solid #ccc;
  box-shadow: 2px 2px 6px 0px rgba(0, 0, 0, 0.3);
}

.grid > article img {
  max-width: 100%;
}

.grid .text {
  padding: 20px;
}

The HTML:

<div id="app" class="container">
    <div class="grid">
        <article v-for="tool in tools">
            <div class="title">
                <h3>{{capitalizeFirstLetter(tool.name)}}</h3>
            </div>
            <div class="description">
                {{tool.description}}
            </div>
        </article>
    </div>
</div>

How do I keep up to 3 cards per row? I can't seem to understand how should I treat the grid so I will keep maximum 3 cards per row. For example I have 8 elements, then It will be:

card card card
card card card
card card

Answer 1

Change grid-template-columns property auto-fill to 3.

body {
  padding: 40px 0;
}

.grid {
  display: grid;
  grid-template-columns: repeat(3, minmax(280px, 1fr));
  grid-gap: 20px;
  align-items: stretch;
}

.grid>article {
  border: 1px solid #ccc;
  box-shadow: 2px 2px 6px 0px rgba(0, 0, 0, 0.3);
}

.grid>article img {
  max-width: 100%;
}

.grid .text {
  padding: 20px;
}
