javascript运行后，页面在右侧被截断

时间：2016-04-26 00:33:58

标签： javascript jquery html css

当我向下滚动时，页面的右侧会被切断并出现毛刺。应该发生的事情是，当您向下滚动页面时，滚动标题直到它到达导航栏，然后导航栏会向下滚动并向下滚动页面的其余部分。我觉得这是一个我忽略的简单错误。任何帮助表示赞赏：）

<script>
var  mn = $(".main-nav");
    mns = "main-nav-scrolled";
    hdr = $('header').height();

$(window).scroll(function() {
  if( $(this).scrollTop() > hdr ) {
    mn.addClass(mns);
  } else {
    mn.removeClass(mns);
  }
});

你的JavaScript看起来很好。我确实注意到你的文档中有一些错误。清理它，使它看起来像这样。 

<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。有许多边距缺少px单位。例如，margin:15。您正在div上应用列表样式。例如list-style-type: none; header, .main-nav-scrolled，-webkit-column-count: 3; /* Chrome, Safari, Opera */ -moz-column-count: 3; /* Firefox */ column-count: 3; ，不需要。还要更新列css，以便它支持所有浏览器。例如; 

<div>

但是.main <ul>的宽度在右侧切断的真正原因，或者只是普通的缩小是因为您在顶级<ul>列表项上使用了浮点数。你需要清除这些浮子。 Read more: All About Floats

发生的事情是，当您滚动并且标题和主导航变得固定时，顶部<div>后面的下一个元素是.main clear:both;。如果您将.main添加到{{1}}以解决您的问题。
