javascript运行后，页面在右侧被切断

当我向下滚动页面的右侧时，会发生切断和毛刺。应该发生的事情是，当您向下滚动页面滚动页眉直到它到达导航栏，然后导航栏粘贴并向下滚动页面的其余部分。我觉得这是我忽略的一个简单的错误。任何帮助表示赞赏:)javascript运行后，页面在右侧被切断

只给''.main'宽度：100％' – danyamachine

你的JavaScript看起来很好。尽管我在文档头中发现了一些错误。清理它，看起来像这样。

<head> 
<meta charset="utf-8"> 
<title>Officers</title> 
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> 
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1"> 
<link href="css/style.css" rel="stylesheet" type="text/css" media="all"> 
<link href="css/owl.carousel2.css" rel="stylesheet" type="text/css"> 
<link href="css/magnific-popup.css" rel="stylesheet" type="text/css"> 
<link href="css/paragraph.css" rel="stylesheet" type="text/css"> 
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script> 
</head>

你的CSS也有一些错误。有一些边缘缺少px单位。例如，margin:15。你在div上应用列表样式。例如，在header, .main-nav-scrolled上的list-style-type: none;，这不是必需的。同时更新你的列CSS，使其支持所有浏览器。例如;

-webkit-column-count: 3; /* Chrome, Safari, Opera */ 
-moz-column-count: 3; /* Firefox */ 
column-count: 3;

但真正的原因。主要<div>的宽度切断右边，或只是简单越走越窄是因为彩车已在顶部<ul>列表项使用。你需要清除这些浮标。 Read more: All About Floats

发生了什么事是，当你滚动并成为标题和主导航固定后面的顶部<ul>下一个元素是。主要<div>。如果您将clear:both;添加到.main即可解决您的问题。

感谢一大堆。我发现这个社区有很多人会花时间帮助别人解决他们的编码问题。我从中学到了很多东西，希望最终能够把这种恩惠归还给其他人。再次感谢一吨:) – VladKrav
