我已经在我的知识范围内尝试了大多数事情，使菜单行与我的导航栏一致，但它不会起作用。以下是相关的CSS，HTML和Javascript代码..

＆＃13;
＆＃13; 
  (function($) {

  $.fn.menumaker = function(options) {
      
      var cssmenu = $(this), settings = $.extend({
        title: "Menu",
        format: "dropdown",
        sticky: false
      }, options);

      return this.each(function() {
        cssmenu.prepend('<div id="menu-button">' + settings.title + '</div>');
        $(this).find("#menu-button").on('click', function(){
          $(this).toggleClass('menu-opened');
          var mainmenu = $(this).next('ul');
          if (mainmenu.hasClass('open')) { 
            mainmenu.hide().removeClass('open');
          }
          else {
            mainmenu.show().addClass('open');
            if (settings.format === "dropdown") {
              mainmenu.find('ul').show();
            }
          }
        });

        cssmenu.find('li ul').parent().addClass('has-sub');

        multiTg = function() {
          cssmenu.find(".has-sub").prepend('<span class="submenu-button"></span>');
          cssmenu.find('.submenu-button').on('click', function() {
            $(this).toggleClass('submenu-opened');
            if ($(this).siblings('ul').hasClass('open')) {
              $(this).siblings('ul').removeClass('open').hide();
            }
            else {
              $(this).siblings('ul').addClass('open').show();
            }
          });
        };

        if (settings.format === 'multitoggle') multiTg();
        else cssmenu.addClass('dropdown');

        if (settings.sticky === true) cssmenu.css('position', 'fixed');

        resizeFix = function() {
          if ($( window ).width() > 768) {
            cssmenu.find('ul').show();
          }

          if ($(window).width() <= 768) {
            cssmenu.find('ul').hide().removeClass('open');
          }
        };
        resizeFix();
        return $(window).on('resize', resizeFix);

      });
  };
})(jQuery);

(function($){
$(document).ready(function(){

$(document).ready(function() {
  $("#cssmenu").menumaker({
    title: "Menu",
    format: "multitoggle"
  });

  $("#cssmenu").prepend("<div id='menu-line'></div>");

var foundActive = false, activeElement, linePosition = 0, menuLine = $("#cssmenu #menu-line"), lineWidth, defaultPosition, defaultWidth;

$("#cssmenu > ul > li").each(function() {
  if ($(this).hasClass('active')) {
    activeElement = $(this);
    foundActive = true;
  }
});

defaultWidth = lineWidth = activeElement.width();

defaultPosition = linePosition = activeElement.position().left;

menuLine.css("width", lineWidth);
menuLine.css("left", linePosition);

$("#cssmenu > ul > li").hover(function() {
  activeElement = $(this);
  lineWidth = activeElement.width();
  linePosition = activeElement.position().left;
  menuLine.css("width", lineWidth);
  menuLine.css("left", linePosition);
}, 
function() {
  menuLine.css("left", defaultPosition);
  menuLine.css("width", defaultWidth);
});

});


});
})(jQuery);

你可以在不使用jQuery的情况下完成。

只需使用CSS：hover选择器，如
void getPositionXAtHeight(float height, Vec2 pos, Vec2 vel, float gravityForce = 9.8f, float gameWidth, float& positionX) { float a = gravityForce / 2.0f; float b = vel.y; float c = pos.y - height; float t = (sqrtf((b * b) - (4.0f * a * c)) - b) / (2.0f * a); positionX = pos.x + (vel.x*t); }

这是一个很好的响应式flexbox解决方案，您可以从...中借用一些想法。
