在为具有更通用的“ li”元素标识符的每个列表项应用样式之后,我尝试为每个单独的列表项应用样式。这些元素目前仅应用了li样式,即使(我相信)React中className的更具体的选择器具有以下在SCSS样式表中定义的样式。
用于下拉式React Components的SCSS,其中包含li元素
& .dropdownUl {
margin: $boxMargin;
padding: $stdPad;
float: left;
position: relative;
& li {
padding: $stdPad;
box-sizing: content-box;
@include standard-1px-border;
position: absolute;
background: $linear-gradient-azn-nfx;
&:hover {
cursor: pointer;
background: $netflix-red;
color: $netflix-white;
}
&:active {
background: darken($netflix-red, 10%);
}
& .dropdownLiTwo {
top: 200px;
background: black;
}
& .dropdownLiThree {
top: 400px;
background: black;
}
}
}
}
}
以下是组件(下拉菜单):
import React from "react";
export default class DropdownUlOne extends React.Component {
constructor(props) {
super(props);
this.state = { showListItems: false };
this.handleMouseEnter = this.handleMouseEnter.bind(this);
this.handleMouseLeave = this.handleMouseLeave.bind(this);
}
handleMouseEnter(e) {
e.preventDefault();
this.setState({
showListItems: true
});
}
handleMouseLeave(e) {
e.preventDefault();
this.setState({ showListItems: false });
}
render() {
if (this.state.showListItems) {
return (
<React.Fragment>
<ul className="dropdownUl" onMouseLeave={this.handleMouseLeave}>
<h2 className="hoverOn">Home</h2>
<li className="dropdownLiOne">Blog</li>
<li className="dropdownLiTwo">UI & UX</li>
<li className="dropdownLiThree">What you can expect</li>
</ul>
</React.Fragment>
);
}
return (
<React.Fragment>
<ul className="dropdownUl" onMouseEnter={this.handleMouseEnter}>
<h2>Home</h2>
</ul>
</React.Fragment>
);
}
}
在此组件中呈现了哪些内容,scss的css导入到该组件中:
import React from "react";
import "../styles/header.css";
import DropdownUlOne from "./dropdownUlOne";
import DropdownUlTwo from "./dropdownUlTwo";
import DropdownUlThree from "./dropdownUlThree";
export default class Header extends React.Component {
render() {
return (
<header className="header">
<h1 className="appTitle">Ronnlid Websites</h1>
<div className="dropdownDiv">
<DropdownUlOne />
<DropdownUlTwo />
<DropdownUlThree />
</div>
</header>
);
}
}
谢谢您的帮助!

我可能误解了您的问题。但是,我认为您此处关于LI样式不适用的问题是因为&
选择器就在它们之前,因此请尝试:
& .dropdownUl {
margin: $boxMargin;
padding: $stdPad;
float: left;
position: relative;
li {
padding: $stdPad;
....
scss的结构方式现在是针对具有您在ul上的类的li,例如:<li class="dropdownUl">
