【CSS + ElementUI】更改 el-carousel 指示器样式且隐藏左右箭头

1. 需求
   前三条数据以走马灯形式展现，指示器 hover 时可以切换到对应内容
   

2. 实现

<template><div v-loading="latestLoading"><div class="upload-first" v-show="latestThreeList.length > 0"><el-carousel indicator-position="outside" height="180px" :autoplay="autoplay"><el-carousel-item v-for="(item) in latestThreeList" :key="item.id"><div class="carousel-content" @click="handleDetail(item.id)"><div class="first-title"><span>{{ item.kind}}</span></div><div class="first-subtitle">{{ item.title }}</div><div class="first-summary">{{ item.summary }}</div><div class="first-time">{{ item.createTime | formatTimer(item.createTime) }}</div></div></el-carousel-item></el-carousel></div></div>
</template>
<script>
import { getList } from '@/api/xxx'
import { dateFormat } from '@/utils/utils'
export default {data(){return{latestLoading:false,latestThreeList: [],query:{pageNum:1,pageSize:10}}},mounted(){this.fetchData()},filters: {formatTimer(date) {return dateFormat(new Date(date),"yyyy-MM-dd")}},methods:{fetchData(){this.latestLoading = truegetList(this.query).then(res=>{this.latestThreeList = res.data.slice(0, 3)this.latestLoading = false})},handleDetail(id){// 跳转到详情页}}
}
</script>
<style lang="less"> 
.upload-first {padding-bottom: 12px;flex-direction: column;align-items: flex-start;gap: 8px;align-self: stretch;border-radius: 10px;width: 976px;height: 184px;background: rgba(4, 106, 249, 0.05);margin: 24px auto;padding: 0 16px 0 0;.carousel-content:hover {color: #023fb5;cursor: pointer;}.first-title {display: flex;justify-content: flex-start;align-items: center;span {color: #2AC91C;font-family: "Source Han Sans CN";font-size: 12px;font-style: normal;font-weight: 400;line-height: 24px;border-radius: 0px 0px 20px 0px;background: #D6FFDE;padding: 8px 12px;}}.first-subtitle {color: #333;font-family: "Source Han Sans CN";font-size: 18px;font-style: normal;font-weight: 500;line-height: 24px;padding: 16px;}.first-subtitle:hover {color: #023fb5;cursor: pointer;}.first-summary {color: #666;font-family: "Source Han Sans CN";font-size: 16px;font-style: normal;font-weight: 400;line-height: 24px;padding: 0 16px;display: -webkit-box;/*! autoprefixer: off */-webkit-box-orient: vertical;/* autoprefixer: on */-webkit-line-clamp: 2;overflow: hidden;height: 48px;}.first-time {color: #666;font-family: "Source Han Sans CN";font-size: 14px;font-style: normal;font-weight: 350;line-height: 24px;text-align: right;}}.el-carousel__arrow { // 隐藏左右箭头display: none;}.el-carousel__indicator { // 改变指示器非选中下样式.el-carousel__button {width: 10px;height: 10px;border-radius: 50%;background-color: #f0f0f0;opacity: 1 !important;}}.el-carousel__indicator.is-active button { // 改变指示器选中时的样式background-color: #023FB5 !important;border-radius: 50%;outline: none;width: 8px;height: 8px;&:active {display: contents; // 解决左右箭头和指示器点击时有黑色边框}}
</style>

3. 问题解决
   隐藏左右箭头，用 display: none;
   鼠标点击，出现黑边框，用display: contents;
   
   

4. 最终效果
   

5. 数据结构

[{id:1,kind:'课题成果',title:'测试股1',summary:'测试股1',createTime:'2024-01-31 14:16:41'},{id:2,kind:'政策',title:'第二十条',summary:'摘要',createTime:'2024-02-04 15:16:41'}
]

6. 日期格式化 @/utils/utils

/*** 日期格式化*/
export function dateFormat(date, format) {format = format || "yyyy-MM-dd hh:mm:ss";if (date !== "Invalid Date") {let o = {"M+": date.getMonth() + 1, //month"d+": date.getDate(), //day"h+": date.getHours(), //hour"m+": date.getMinutes(), //minute"s+": date.getSeconds(), //second"q+": Math.floor((date.getMonth() + 3) / 3), //quarterS: date.getMilliseconds() //millisecond};if (/(y+)/.test(format))format = format.replace(RegExp.$1,(date.getFullYear() + "").substr(4 - RegExp.$1.length));for (let k in o)if (new RegExp("(" + k + ")").test(format))format = format.replace(RegExp.$1,RegExp.$1.length === 1 ?o[k] :("00" + o[k]).substr(("" + o[k]).length));return format;}return "";
}
