【问题描述】:
我首先为我的 Todo 列表应用程序制作静态 html 设计和 css,然后将它们传递给 react 组件。
我不知道为什么 li 中的跨度没有向右移动,但是在尝试删除内容并弄清楚什么有效和什么无效之后,我发现 li css 没有改变任何东西不仅仅是颜色,所以例如,如果我尝试更改行高或高度没有任何改变,并且认为整个样式不起作用,但颜色确实有效,但其他一切都没有。是否有某种风格阻碍了改变大小和放置物品的能力?
这里是 app.js:
import React, { useState } from "react";
import "./App.css";
import axios from "axios";
import { FontAwesomeIcon } from "@fortawesome/react-fontawesome";
import { faTrash, faPlus } from "@fortawesome/free-solid-svg-icons";
function App() {
return (
<>
<div className="backgound">
<div className="wrapper">
<header>Todo app MERN</header>
<div className="inputField">
<input type="text" placeholder="Add your new task"></input>
<button>
<FontAwesomeIcon icon={faPlus} />
</button>
</div>
<ul className="todoList">
<li>
Do something
<span>
<FontAwesomeIcon icon={faTrash} />
</span>
</li>
<li>
Buy something
<span>
<FontAwesomeIcon icon={faTrash} />
</span>
</li>
<li>
Learn something
<span>
<FontAwesomeIcon icon={faTrash} />
</span>
</li>
</ul>
<div class="footer">
<span> You have 3 pending tasks</span>
<button>Clear</button>
</div>
</div>
</div>
</>
);
}
export default App;
这是css,导致我出现问题的两种样式是 .todoList li 和 .todoList li span:
* {
margin: 0;
padding: 0;
box-sizing: border-box;
font-family: 'Poppins', sans-serif;
}
::selection {
color: #ffff;
background: rgb(142, 73, 232);
}

height: 100vh;
padding: 10px;

}
.wrapper {
background: #fff;
max-width: 400px;
width: 100%;
margin: 120px auto;
padding: 25px;
border-radius: 5px;

}

font-weight: 600;
}
.wrapper .inputField {

}
.inputField input {

border-radius: 3px;

font-size: 17px;
padding-left: 15px;
transition: all 0.3s ease;
}
.inputField input:focus {
border-color: #8E49E8;
}
.inputField button {

border-radius: 3px;
opacity: 0.6;
pointer-events: none;
transition: all 0.3s ease;
}
.inputField button:hover,
.footer button:hover {
background: #721ce3;
}
.inputField button.active {
opacity: 1;
pointer-events: auto;
}
.wrapper .todoList {
max-height: 250px;
overflow-y: auto;
}
.todoList li {
list-style: none;
height: 45 px;
line-height: 45 px;
position: relative;
background: #f2f2f2;
border-radius: 3px;
margin-bottom: 8 px;
padding: 0 15 px;
}
.todoList li span {
position: absolute;
right: 0 px;
color: #e74c3c;
}
.wrapper .footer {
display: flex;
width: 100%;
margin-top: 20px;
align-items: center;
justify-content: space-between;
}
.footer button {
padding: 6px 10px;
border-radius: 3px;
border: none;
outline: none;
color: #fff;
font-weight: 400;
font-size: 16px;
margin-left: 5px;
background: #8E49E8;
cursor: pointer;
user-select: none;
opacity: 0.6;
pointer-events: none;
transition: all 0.3s ease;
}
.footer button.active {
opacity: 1;
pointer-events: auto;
}
