我是 html/css 的初学者,我正在通过 bootstrap 封面示例 ( http://getbootstrap.com/examples/cover/ ) 实现一个网站。我为主页、功能和联系页面使用相同的布局。但是在“功能”页面中,我有一个更大的内容需要滚动。但是这个 css 不允许这样做,导致元素被定位在中心并且页面保持浏览器屏幕的大小。我想进行更改,以便页面根据我添加的内容量(没有固定大小)增长,保持相同的布局样式,而且我在测试中遇到的另一个问题是导航栏是固定的并且覆盖了内容在滚动期间。

CSS:

/*
* Globals
*/

/* Links */
a,
a:focus,
a:hover {
color: #fff;
}

/* Custom default button */
.btn-default,
.btn-default:hover,
.btn-default:focus {
color: #333;
text-shadow: none; /* Prevent inheritance from `body` */
background-color: #fff;
border: 1px solid #fff;
}


/*
* Base structure
*/

html,
body {

height: 1000px;
/*
padding-bottom: 70px;
padding-top: 70px;*/
background-color: #333;
}
body {
color: #fff;
text-align: center;
text-shadow: 0 1px 3px rgba(0,0,0,.5);
}

/* Extra markup and styles for table-esque vertical and horizontal centering */
.site-wrapper {
display: table;
width: 100%;
height: 100%; /* For at least Firefox */
min-height: 100%;
-webkit-box-shadow: inset 0 0 100px rgba(0,0,0,.5);
box-shadow: inset 0 0 100px rgba(0,0,0,.5);
}
.site-wrapper-inner {
display: table-cell;
vertical-align: top;
}
.cover-container {
margin-right: auto;
margin-left: auto;
}

/* Padding for spacing */
.inner {
padding: 30px;
}


/*
* Header
*/
.masthead-brand {
margin-top: 10px;
margin-bottom: 10px;
}

.masthead-nav > li {
display: inline-block;
}
.masthead-nav > li + li {
margin-left: 20px;
}
.masthead-nav > li > a {
padding-right: 0;
padding-left: 0;
font-size: 16px;
font-weight: bold;
color: #fff; /* IE8 proofing */
color: rgba(255,255,255,.75);
border-bottom: 2px solid transparent;
}
.masthead-nav > li > a:hover,
.masthead-nav > li > a:focus {
background-color: transparent;
border-bottom-color: #a9a9a9;
border-bottom-color: rgba(255,255,255,.25);
}
.masthead-nav > .active > a,
.masthead-nav > .active > a:hover,
.masthead-nav > .active > a:focus {
color: #fff;
border-bottom-color: #fff;
}

@media (min-width: 768px) {
.masthead-brand {
float: left;
}
.masthead-nav {
float: right;
}
}


/*
* Cover
*/

.cover {
padding: 0 20px;
}
.cover .btn-lg {
padding: 10px 20px;
font-weight: bold;
}


/*
* Footer
*/

.mastfoot {
color: #999; /* IE8 proofing */
color: rgba(255,255,255,.5);
}


/*
* Affix and center
*/

@media (min-width: 768px) {
/* Pull out the header and footer */
.masthead {
position: fixed;
top: 0;
}
.mastfoot {
position: fixed;
bottom: 0;
}
/* Start the vertical centering */
.site-wrapper-inner {
vertical-align: middle;
}
/* Handle the widths */
.masthead,
.mastfoot,
.cover-container {
width: 100%; /* Must be percentage or pixels for horizontal alignment */
}
}

@media (min-width: 992px) {
.masthead,
.mastfoot,
.cover-container {
width: 700px;
}
}

最佳答案

您在媒体查询上有一些 fixed position 导致了这种情况。

@media (min-width: 768px) 中注释以下属性:

.masthead {
/* position: fixed; */
/* top: 0; */
}
.mastfoot {
/* position: fixed; */
/* bottom: 0; */
}

  • 请注意,我将 background: gray 添加到 body 只是为了查看 nav 链接。
