我想让我的导航栏固定在顶部并在我打开折叠菜单时按下内容，就像通常在静态或只是导航中所做的那样。

像这样:(https://getbootstrap.com/examples/navbar-static-top/)但我希望导航栏固定在顶部。

我之前读过这个:Navbar-fixed-top pushes content on page up

但是加padding不行，请帮我解决这个问题xD

我的代码

CSS 和 HTML:

/*------------------------------------------------- Hero Image -------------------------------------------------*/

		.calltoaction {
		text-align: center;
		-webkit-user-select: none; /* Chrome/Safari */
		-moz-user-select: none; /* Firefox */
		-ms-user-select: none; /* IE10+ */
		/* Rules below not implemented in browsers yet */
		-o-user-select: none;
		user-select: none;
		}

		.calltoaction h1 {
		text-align: center;
		display: inline-block;
		font-size: 70px;
		/*text-transform: uppercase;*/
		letter-spacing: 2px;
		border: 8px solid #FFFFFF;
		border-radius: 13px;
		padding: 17px 20px;
		color: white;
		font-family: sans-serif;
		font-weight: 900;
		}

		.calltoaction h3 {
		color: #FFFFFF;
		font-size: 29px;
		text-align: center;
		}


		#hero-image {
		height: 870px;
		background: #e8eced url('http://twnateserver.no-ip.org/Pictures/taiwan-taipei.jpg') no-repeat center;
		}

		#hero-image h1 {
		margin: 215px 0 7px 0;
		}

		#hero-image h3 {
		margin: 3% 0 7px 0;
		}


		/*#hero-image a {
		margin: 3% 0 7px 0;
		}*/



/*------------------------------------------------- Hero Image -------------------------------------------------*/




/*------------------------------------------------- navbar----------------------------------------------*/
.navbar {
background-color: rgba(15, 91, 121, 0.03);
background: rgba(15, 91, 121, 0.03);
border-color: rgba(15, 91, 121, 0.03);
margin-bottom: 0px;

/*Line 4213-4217 in Bootstrap.css*/
/*Goal effect: http://www.w3schools.com/bootstrap/tryit.asp?filename=trybs_navbar_collapse&stacked=h*/

}

.navbar li {
color: #000;
}


.dropdown-menu {
  position: absolute;
  top: 100%;
  left: 0;
  z-index: 1000;
  display: none;
  float: left;
  min-width: 160px;
  padding: 5px 0;
  margin: 2px 0 0;
  font-size: 14px;
  text-align: left;
  list-style: none;
  background-color: rgba(233, 237, 239, 0.42);
  -webkit-background-clip: padding-box;
          background-clip: padding-box;
  border: 1px solid #ccc;
  border: 1px solid rgba(15, 91, 121, 0.03);
  border-radius: 4px;
  -webkit-box-shadow: 0 6px 12px rgba(0, 0, 0, .175);
          box-shadow: 0 6px 12px rgba(0, 0, 0, .175);
}

最佳答案

如果padding不适合你，试试这个 <nav> :

nav.navbar-fixed-top {
  position:fixed;
  top:0;
}

然后是下面的 <body> :

body::before {
  display:block;
  content: '';
  height:60px; /* or whatever */
}
