css实现子元素整体居中，最后一行靠左。grid布局

<div class="container">
  <div class="item">1</div>
  <div class="item">2</div>
  <div class="item">3</div>
  <div class="item">4</div>
  <div class="item">5</div> 
  <div class="item">6</div>
  <div class="item">7</div>
  <div class="item">8</div>
  <div class="item">9</div>
  <div class="item">10</div>
</div>


.container{
  display: grid;
  gap: 24px;
  grid-template-columns: repeat(auto-fill, 100px);
  justify-content: center;  //此行代码用于居中
}
.container .item{
    width: 100px;
    height； 100px;
    background-color: #FFA500;
}
