html - 在动态生成的组件中每行最多显示 4 个图标

问题描述

我目前正在开发基于https://ngx-emoji-mart.netlify.app/的表情符号组件。

我希望该组件占用 100% 的父 div 容量，并且每行最多有 4 个项目。这样做的最佳方法是什么？我曾尝试使用 flex-box，但问题是我无法弄清楚如何限制每行的项目数。

我的CSS代码如下：

.emoji-anchor {
  position: relative;
  display: inline-block;
  flex: 1 1 auto;
  color: #858585;
  text-align: center;
  padding: 12px 4px;
  overflow: hidden;
  transition: color 0.1s ease-out;
  margin: 0;
  box-shadow: none;
  background: none;
  border: none;
  flex-wrap: wrap;
}

.emoji-anchors {
  flex-direction: row;
  justify-content: space-between;
  padding: 0 20px 0 25px;
  line-height: 0;
}

完整的代码粘贴起来很长，所以我把它包括在这里：https ://jsfiddle.net/2nxwpL8h/ 。

请记住，组件是在 Angular 中动态创建的，如下所示：

<div class="emoji-anchors">
  <ng-template ngFor let-category [ngForOf]="categories" let-idx="index" [ngForTrackBy]="trackByFn">
    <span
      *ngIf="category.anchor !== false"
      class="emoji-anchor"
      (click)="this.handleClick($event, idx)"
      [class.emoji-anchor-selected]="category.name === selected"
      [style.color]="category.name === selected ? color : null"
    >
      <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 24 24" width="24" height="24">
        <path [attr.d]="icons[category.id]" />
      </svg>
      <span class="emoji-anchor-bar" [style.background-color]="color"></span>
    </span>
  </ng-template>
</div>

解决方案

使用具有 4 个相等列的 CSS 网格

.emoji-anchor {
  color: #858585;
  text-align: center;
  padding: 12px 4px;
}

.emoji-anchors {
  display: grid;
  grid-template-columns: repeat(4, 1fr);
}
<div _ngcontent-urg-c146="" class="emoji-anchors">
