CSS:
.navbar{
padding: 7px 0;
margin-bottom: 0;
}
.jumbotron {
background-image: url(http://cdn.wallpapersafari.com/97/93/UE7u4i.jpg);
background-size: cover;
color: white;
margin: 0;
}
.vertical-center {
min-height: 100%; /* Fallback for browsers do NOT support vh unit */
min-height: 100vh; /* These two lines are counted as one :-) */
display: flex;
align-items: center;
}
.btn-jumbotron{
background-color: black;
border-color: white;
}
我正在尝试让jumbotron拥有浏览器窗口的全高,但没有静态导航栏的高度。我确实通过使用height: min-height:100vh
和它的中心将它设置为完整视口的大小,但正如你可以从jsfiddle示例中看到的那样,由于导航栏的高度 - 64px
,我有一个滚动条。
我该如何删除?

使用calc
.vertical-center {
min-height: 100%; /* Fallback for browsers do NOT support vh unit */
min-height: 100vh; /* These two lines are counted as one :-) */
min-height: calc(100% - 64px); /* */
min-height: calc(100vh - 64px); /* */
display: flex;
align-items: center;
}

添加到.navbar位置:绝对;顶部:0;宽度:100%;和填充顶部:64px;到.jumbotron
