怎么改变el-upload-list el-upload-list--text的css样式

可以通过以下方式修改el-upload-list el-upload-list--text的css样式：

1. 使用scoped样式，将样式限制在组件内部，避免影响到其他组件。

<template>
  <el-upload
    class="upload-demo"
    action="https://jsonplaceholder.typicode.com/posts/"
    :on-preview="handlePreview"
    :on-remove="handleRemove"
    :before-remove="beforeRemove"
    multiple
    list-type="text"
    :file-list="fileList">
    <el-button size="small" type="primary">点击上传</el-button>
    <div slot="tip" class="el-upload__tip">只能上传jpg/png文件，且不超过500kb</div>
  </el-upload>
</template>

<style scoped>
.el-upload-list--text .el-upload-list__item-actions {
  display: none;
}
</style>

2. 使用/deep/或>>>穿透选择器，修改组件内部的样式。

<template>
  <el-upload
    class="upload-demo"
    action="https://jsonplaceholder.typicode.com/posts/"
    :on-preview="handlePreview"
    :on-remove="handleRemove"
    :before-remove="beforeRemove"
    multiple
    list-type="text"
    :file-list="fileList">
    <el-button size="small" type="primary">点击上传</el-button>
    <div slot="tip" class="el-upload__tip">只能上传jpg/png文件，且不超过500kb</div>
  </el-upload>
</template>

<style>
/deep/ .el-upload-list--text .el-upload-list__item-actions {
  display: none;
}
</style>
