    <el-image
      style="width: 100px; height: 100px"
      :src="url"
      :fit="fit"></el-image>
  </div>
</div>

<script>
  export default {
    data() {
      return {
        fits: ['fill', 'contain', 'cover', 'none', 'scale-down'],
        url: 'https://fuss10.elemecdn.com/e/5d/4a731a90594a4af544c0c25941171jpeg.jpeg'
