无法使Bootstrap列的高度充满整个页面

Question

无法使Bootstrap列的高度充满整个页面

htmlcsstwitter-bootstrap

3

我似乎无法使列的高度完全展开。它们的高度略高于总高度，这会创建一个垂直滚动条。我正在遵循这个SO线程的答案。

如果您运行下面的代码，它不会正确工作，但是这个bootply能够正确演示我的问题。两个列在页面底部溢出。

以下是我的代码和bootply。

因为我对bootstrap、html和css并不是很熟悉，如果有更好的方法，请告诉我？谢谢！

我的代码片段：

html, body, .container-fluid {
            height: 100%;
        }

        .container-fluid {
            display: table;
            width: 100%;
            margin-top: -50px;
            padding: 50px 0 0 0; 
            box-sizing: border-box;
        }

        .row {
            height: 100%;
            display: table-row;
        }

        .col-sm-5 {
            background: pink;
            border: 1px solid purple;
        }

        .col-sm-7 {
            background: yellow;
        }

        .row .no-float {
            display: table-cell;
            float: none;
        }

使用CSS的calc()函数可以解决问题。这将帮助您消除垂直滚动条。例如：

html,body,.container {
    height: calc(100% - 18px);
}

同时删除 .container 中的 margin-top: -50px。而是从nav.navbar中删除 margin-bottom。

请查看下面的片段 (使用全屏预览):

html,body,.container {
    height: calc(100% - 18px);
}
nav.navbar {
  margin: 0;
}
.container {
    display: table;
    width: 100% !important;
    padding: 0 !important; /*set left/right padding according to needs*/
    box-sizing: border-box;
}

.row {
    height: 100%;
    display: table-row;
}

.col-md-3 {   
    background: pink;
}
.col-md-9 {
    background: yellow;   
}

.row .no-float {
  display: table-cell;
  float: none;
}
