JQuery toggleClass问题没有按预期工作

我最近开始了一个基于我为我的投资组合网站创建的虚拟公司的项目。我在实现一段jQuery代码时遇到问题，以切换一个名为hidden的类，该类将设置该类所放置的显示为none。我正在使用此类在某些媒体查询断点处切换移动导航。但是隐藏的toggleClass不起作用。你们中的任何人都可以帮忙吗？ 这是我的网站： https://jorgeg1105.github.io/JG-Photography/ 

//When the page loads, Fade in all divs with class hidden.
//Then Remove hidden class.
$(document).ready(function () {
    $('div.hidden').fadeIn(2000).removeClass('hidden');
});

//Fade In all h3 with class hidden.
//Remove hidden class.
$('h3.hidden').fadeIn(3000).removeClass('hidden');

//Image Filter
$(document).ready(function () {
	$("#mainnav ul li a").click(function (){
		var category = $(this).attr("class");

		if (category == "all" ){
			$("#imgcontainer img").addClass("hidden");
			setTimeout(function (){
				$("#imgcontainer img").removeClass("hidden");
			});
		}
		else {
			$("#imgcontainer img").addClass("hidden");
			setTimeout(function(){
				$("."+category).removeClass("hidden");
			});
		}
	});
});


//When burger is clicked. Mobile nav and mainnav are toggled.
$(".burger").on("click", function (){
	$("#mainnav").toggleClass("hidden");
	$(".mobilenav").toggleClass("hidden");
});

答案 0 :(得分：2)

隐藏的toggleClass无效，因为您在媒体查询中设置了CSS规则，如果max-size为600或740，则应用覆盖隐藏类属性的显示块或flex属性以使隐藏类工作那样做：

.hidden{
 display: none !important;    
}

我在这里添加了！important，因为你已经在#mainnav中设置了display属性，它比任何类（没有！important规则）具有更高的优先级，并覆盖了另一个类属性。
