重叠头像：将SCSS转换为CSS，将PUG转换为HTML

Question

我正在尝试在HTML和CSS中创建重叠的头像。 它基于此代码段。 仅此片段在SCSS和PUG中创建。 如何将PUG转换为HTML，如何将SCSS转换为CSS？ 我遇到一个问题，化身彼此距离很远，并且当您将鼠标悬停在化身上时，该名称没有出现。

在这里检查代码。

import React from 'react';
import { render } from 'react-dom';

import './style.css';

class App extends React.Component {
  constructor() {
    super();
    this.state = {
     todos: 
          [

            {name:'Lindsey', avatar: 'https://vignette.wikia.nocookie.net/arresteddevelopment/images/1/16/Season_3_Character_Promos_-_Lindsay_Bluth_F%C3%BCnke_01.jpg/revision/latest?cb=20111027201233'},

          ],
    };
  }

  render() {
    let todos = this.state.todos.map((todo, index) =>
      <Todo
        key={index}
        index={index}
        todo={todo}

      />
    )
    return (
      <div>
        <ul>{todos}</ul>
      </div>
    );
  }
}

class Todo extends React.Component {
  render() {
    const  Background = this.props.todo.avatar;
    const  name = this.props.todo.name;


const profile = {
    "&:hover&:after": {
      position: "absolute",
      content: `attr(${name})`,
      background: "rgba(255, 255, 255, .95)",
      color: "inherit",
      fontSize: "10px",
      padding: "4px",
      width: "auto",
      bottom: "-0.5rem",
      right: "-0.5rem",
      boxShadow: "0px 5px 12px rgba(0, 0, 0, .12)",
      opacity: "0",
      borderRadius: "0.15rem",
      animation: "fade 100ms ease 750ms forwards"
    } 
  }

    return (
      <ul className="c-profile__list">
        <li style={profile} className="c-profile" style={{backgroundImage: `url(${Background})`}}></li>
      </ul>
    );
  }
}

render(<App />, document.getElementById('root'));

Answer 1

从短视...

您正在将ul标签包装在父ul 。 快速解决：

Answer 2

在Todo ，您需要删除每个项目周围的其他<ul>标签，并将您的name添加为title道具：

return (
        <li style={profile} className="c-profile" title={name} style={{backgroundImage: `url(${Background})`}}></li>
    );
