对于全高布局,需要告诉父元素
columns
要获取该视区的所有可用高度,可以定义下一个类:
full-height {
height: 100vh;
}
并将该类分配给
row
包裹着
柱
. 在此之后,您需要设置
height
三列的属性
100%
(因此它们将使用父元素的100%高度)。
现在,在小型设备上(
性虐待
,您希望更改以前的布局:所有列都将使用12个可用的引导网格。因此,您必须使用与下一个类似的媒体查询来管理列的高度(这里记录了引导3个断点:
Bootstrap 3 Media Queries
):
@media only screen and (max-width : 992px) {
.leftHalf {
height: 40%;
}
.centerHalf {
height: 20%;
}
.rightHalf {
height: 40%;
}
}
前面的所有解释都用于下一个工作示例,检查它是否在全屏模式下播放,并调整浏览器的大小。这是你的家庭作业,正确显示中间的布局
navbar
. 希望这能帮助您作为所需布局的基础。
.full-height {
height: 100vh;
}
