html - 嵌套选项卡之间的空间

Question

任何人都可以解释为什么在嵌套选项卡中我将它放在第二个选项卡(名为“Letture”的选项卡)中，选项卡右侧有一个空格，而在第一个选项卡中却没有？

两个选项卡的 CSS 代码相同，我不明白为什么它们的行为不同

$('ul.tabs li').click(function(){
		var tab_id = $(this).attr('data-tab');

		$('ul.tabs li').removeClass('current');
		$('.tab-content').removeClass('current');

		$(this).addClass('current');
		$("#"+tab_id).addClass('current');
		
		$('ul.tabs li').each(function () {
			var nimg = $(this).find('img').attr('src');
			$(this).find('img').attr('src', nimg.replace('_r', '_g'));
		});
		
		var img = $(this).find( 'img' ).attr('src');
		$(this).find( 'img' ).attr('src', img.replace('_g', '_r'));
		
	});
$("ul.subtabs li").click(function(){
			var tab_id = $(this).attr("data-tab");

			$("ul.subtabs li").removeClass("current");
			$(".subtab-content").removeClass("current");

			$(this).addClass("current");
			$("#"+tab_id).addClass("current");
			
			$("ul.subtabs li").each(function () {
				var nimg = $(this).find("img").attr("src");
				$(this).find("img").attr("src", nimg.replace("_r", "_g"));
			});
			
			var img = $(this).find( "img" ).attr("src");
			$(this).find( "img" ).attr("src", img.replace("_g", "_r"));
		});

Answer 1

这是因为它们显示为 inline-block ，这是一个内联元素，因此会产生间隙，因此解决此问题的一种方法是设置 font-size:0 到父 ul。
