当一个元素悬停并影响CSS中的另一个元素/类时，如何添加悬停效果？

拉纳博士

当我将鼠标悬停在一个班上时会怎么办？

如果我将鼠标悬停.service_text并.service_icon应该更改的背景颜色.service_bar_1

例如链接：https://codepen.io/aasaadzaman5/pen/XWJPjpN时

.service_content .service_text:hover .service_bar_1,
.service_content .service_text:hover .service_bar_2,
.service_content .service_text:hover .service_bar_3 { 
          background-color: #e74c3c; 
          height: 2px; 
 }

通过jquery可以实现。在您的代码笔中尝试以下代码

$(document).ready(function() {
  $(".service_icon_1").hover(function() {
    $(".service_bar_1").css("background-color","#e74c3c");
  }, function() {
    $(".service_bar_1").css("background-color","#2a2a2a");
  });
   $(".service_icon_2").hover(function() {
    $(".service_bar_2").css("background-color","#e74c3c");
  }, function() {
    $(".service_bar_2").css("background-color","#2a2a2a");
  });
   $(".service_icon_3").hover(function() {
    $(".service_bar_3").css("background-color","#e74c3c");
  }, function() {
    $(".service_bar_3").css("background-color","#2a2a2a");
  });
});

Codepen中的代码段

  $(".service_icon_1").hover(function() {
    $(".service_bar_1").css("background-color","#e74c3c");
  }, function() {
    $(".service_bar_1").css("background-color","#2a2a2a");

   $(".service_icon_2").hover(function() {
    $(".service_bar_2").css("background-color","#e74c3c");
  }, function() {
    $(".service_bar_2").css("background-color","#2a2a2a");
  });
   $(".service_icon_3").hover(function() {
    $(".service_bar_3").css("background-color","#e74c3c");
  }, function() {
    $(".service_bar_3").css("background-color","#2a2a2a");
