The grid enables you to align the elements in multiple rows and columns. You can make multiple layouts using the grid. Below is an example of three by three column grid layout.

Html:

 <div class="outer-div">
        <div class="inner-div">1</div>
        <div class="inner-div">2</div>
        <div class="inner-div">3</div>
        <div class="inner-div">4</div>
        <div class="inner-div">5</div>
        <div class="inner-div">6</div>
        <div class="inner-div">7</div>
        <div class="inner-div">8</div>
        <div class="inner-div">9</div>
    </div>

Css:

.outer-div {
    display: grid;
    grid-template-columns: repeat(3, 1fr);
    grid-template-rows: repeat(3, 1fr);
}
.inner-div {
    height: 100px;
    width: 100px;
    background-color: crimson;
    border: solid 2px white;
    margin-bottom: 20px;
}
