kab*_*ice 4 html css twitter-bootstrap bootstrap-4
这篇文章可能听起来像重复，但事实并非如此，请先阅读。
我希望主容器 ( <main role="main" class="container">) 使用 Bootstrap 4 在页眉和页脚之间是全高的。这是我的 html 代码：
// Initialize tooltip component
$(function () {
$('[data-toggle="tooltip"]').tooltip()
})
// Initialize popover component
$(function () {
$('[data-toggle="popover"]').popover()
}).container{
width: 100%; min-height: 100% !important;
min-height:calc(100% - 110px); !important;
margin: 0 auto -33px;
border: solid blue;
}<!DOCTYPE html>

还有更多……但在我的情况下没有任何作用。
请帮忙！
Flexbox 也是您的朋友。
\n\n\n\n\n然而，在您继续阅读之前：您不应该再使用已经发布的
\nalphaBootstrap 4 版本！beta 2
.container {\r\n border: solid blue; \r\n}\r\n\r\nhtml {\r\n height: 100%;\r\n}\r\nbody {\r\n display: flex;\r\n flex-direction: column;\r\n min-height: 100vh;\r\n}\r\n\r\nmain {\r\n flex: 1;\r\n margin-top: 56px;\r\n}\r\n\r\nfooter {\r\n height: 10vh;\r\n}<header>\r\n <nav class="navbar navbar-toggleable-md navbar-inverse bg-inverse fixed-top">\r\n <button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarsExampleDefault" aria-controls="navbarsExampleDefault" aria-expanded="false" aria-label="Toggle navigation">\r\n <span class="navbar-toggler-icon"></span>\r\n </button>\r\n <a class="navbar-brand" href="#" data-placement="right" data-animation="false" data-toggle="tooltip" title="Aller \xc3\xa0 Mes Summaries">My Logo</a>\r\n </nav>\r\n</header>\r\n\r\n\r\n<!-- Begin page content -->\r\n<main role="main" class="container">\r\n <div class="row mt-3" style="border: solid green">\r\n <div class="col-sm-12 col-md-3" style="border: solid red; height: 200%;">col</div>\r\n <div class="col-sm-12 col-md-5">col</div>\r\n <div class="col-sm-12 col-md-4">col</div>\r\n </div>\r\n</main>\r\n\r\n<footer>\r\n <nav class="navbar navbar-toggleable-md navbar-inverse bg-inverse h-100"></nav>\r\n</footer>\r\n\r\n\r\n<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.6/css/bootstrap.min.css" rel="stylesheet"/>基本上，这个解决方案创建了body一个弹性容器，其中的项目堆叠在列中。就位后，flex: 1;进行<main>拉伸<main>以填充可用高度并推<footer>入底部。这样.fixed-bottom就不再需要了。
更新：\n我已更新上面的标记以符合 Bootstrap 4 beta 2。如下：
html {\r\n height: 100vh;\r\n}\r\n\r\nbody {\r\n display: flex;\r\n flex-direction: column;\r\n min-height: 100vh;\r\n}\r\n\r\nmain {\r\n flex: 1;\r\n margin-top: 56px;\r\n}\r\n\r\nfooter {\r\n height: 10vh;\r\n}\r\n\r\n.container {\r\n border: solid blue; \r\n}<header>\r\n <nav class="navbar navbar-expand-md navbar-dark bg-dark fixed-top">\r\n <button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarsExampleDefault" aria-controls="navbarsExampleDefault" aria-expanded="false" aria-label="Toggle navigation">\r\n <span class="navbar-toggler-icon"></span>\r\n </button>\r\n <a class="navbar-brand" href="#" data-placement="right" data-animation="false" data-toggle="tooltip" title="Aller \xc3\xa0 Mes Summaries">My Logo</a>\r\n </nav>\r\n</header>\r\n\r\n<!-- Begin page content -->\r\n<main role="main" class="container">\r\n <div class="row mt-3" style="border: solid green">\r\n <div class="col-sm-12 col-md-3" style="border: solid red; height: 200%;">col</div>\r\n <div class="col-sm-12 col-md-5">col</div>\r\n <div class="col-sm-12 col-md-4">col</div>\r\n </div>\r\n</main>\r\n\r\n<footer>\r\n <nav class="navbar navbar-toggleable-md navbar-inverse bg-dark h-100"></nav>\r\n</footer>\r\n\r\n\r\n<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta.2/css/bootstrap.min.css" rel="stylesheet"/>要将标记从alpha 6to更新beta 2，您必须进行以下更改：重命名.navbar-expand-md为.navbar-expand-md、.navbar-inverseto.navbar-dark和.bg-inverseto .bg-dark。
使用较新的 Bootstrap 4.4.x 类重新审视这个问题（不需要额外的 CSS）
<div class="d-flex flex-column overflow-hidden min-vh-100 vh-100">
<header>
<nav class="navbar navbar-expand-md navbar-dark bg-dark">
...
</nav>
</header>
<main role="main" class="flex-grow-1 overflow-auto">
<div class="container">
<div class="row mt-3">
<div class="col-sm-12 col-md-3">
Aside
</div>
<div class="col">
Main
</div>
</div>
</div>
</main>
<footer class="container-fluid flex-grow-0 flex-shrink-1">
...
</footer>
</div>
结果是全高布局页眉/导航、页脚和中间滚动的主要内容区域。无论页面高度如何，页脚始终位于底部。
