我真的被我网站上的一个小问题困住了。
每当我向我的 HTML 添加一个视口(viewport)时，即使没有溢出的内容，它也会创建一个滚动条。
我使用 Bootstrap 作为 CSS 框架。
body {
/* Location of the image */
background-image: url(http://www.haristechnology.com/images/footer_lodyas.png);
/* Background image is centered vertically and horizontally at all times */
background-position: center center;
/* Background image doesn't tile */
background-repeat: no-repeat;
/* Background image is fixed in the viewport so that it doesn't move when
the content's height is greater than the image's height */
background-attachment: fixed;
/* This is what makes the background image rescale based
on the container's size */
background-size: cover;
/* Set a background color that will be displayed
while the background image is loading */
}
ul {
list-style-type: none;
margin: 0;
padding: 0;
overflow: hidden;
}
.navbar-default .navbar-brand {
color: rgba(255, 255, 255, 1);
}
.navbar-default {
font-size: 26px;
background-color: rgba(0, 0, 0, 1);
border-width: 0px;
border-radius: 0px;
}
.navbar-default .navbar-nav>li>a {
color: rgba(255, 255, 255, 1);
background-color: rgba(0, 0, 0, 1);
}
.navbar-default .navbar-nav>li>a:hover,
.navbar-default .navbar-nav>li>a:focus {
color: rgba(255, 255, 255, 1);
background-color: rgba(12, 245, 229, 0.59);
}
.navbar-default .navbar-nav>.active>a,
.navbar-default .navbar-nav>.active>a:hover,
.navbar-default .navbar-nav>.active>a:focus {
color: rgba(20, 250, 39, 1);
background-color: rgba(0, 0, 0, 1);
}
.navbar-default .navbar-toggle {
border-color: #000000;
}
.navbar-default .navbar-toggle:hover,
#nav.navbar-default .navbar-toggle:focus {
background-color: #000000;
}
.navbar-default .navbar-toggle .icon-bar {
background-color: #000000;
}
.navbar-default .navbar-toggle:hover .icon-bar,
.navbar-default .navbar-toggle:focus .icon-bar {
background-color: #000000;
}
.custom{
margin-top:15%;
}

如有任何帮助，我们将不胜感激。
注意:到目前为止，此问题仅在 Chrome 中发生，而在 Internet Explorer 中未发生？
最佳答案
这是你的 div#nav。当您将 Logo 从底部向上设置动画时，Chrome 无法正确计算高度，并且文档底部会出现大量溢出。
在您的 div#nav 的 CSS 中，添加 overflow: hidden;，您的问题就会消失。
关于css - 没有内容只是背景，为什么有滚动条？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/30175861/
