Can't make 100% div height between header and footer with Bootstrap 4

问题

This post could sound like a duplicate but it isn't, please read first.

I want the main container (<main role="main" class="container">) to be full-height between header and footer using Bootstrap 4. Here is my html code :

// 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; 
}

Flexbox is your friend here too.

However, before you read any further: you should not use the alpha version of Bootstrap 4 any more as beta 2 is out!

.container {
    border: solid blue; 
}

html {
    height: 100%;
}
body {
    display: flex;
    flex-direction: column;
    min-height: 100vh;
}

main {
    flex: 1;
    margin-top: 56px;
}

footer {
    height: 10vh;
}

<header>
    <nav class="navbar navbar-toggleable-md navbar-inverse bg-inverse fixed-top">
        <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">
            <span class="navbar-toggler-icon"></span>
        </button>
        <a class="navbar-brand" href="#" data-placement="right" data-animation="false" data-toggle="tooltip" title="Aller à Mes Summaries">My Logo</a>
    </nav>
</header>


<!-- Begin page content -->
<main role="main" class="container">
    <div class="row mt-3" style="border: solid green">
        <div class="col-sm-12 col-md-3" style="border: solid red; height: 200%;">col</div>
        <div class="col-sm-12 col-md-5">col</div>
        <div class="col-sm-12 col-md-4">col</div>
    </div>
</main>

<footer>
    <nav class="navbar navbar-toggleable-md navbar-inverse bg-inverse h-100"></nav>
</footer>


<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.6/css/bootstrap.min.css" rel="stylesheet"/>

Basically this solution makes body a flex container with it's items stacked in columns. With that in place, flex: 1; on <main> stretches <main> to fill the available height and pushing <footer> into the bottom. With that .fixed-bottom is not needed any more.

Update: I've updated the markup above to conform Bootstrap 4 beta 2. This is as follows:

html {
    height: 100vh;
}

body {
    display: flex;
    flex-direction: column;
    min-height: 100vh;
}

main {
    flex: 1;
    margin-top: 56px;
}

footer {
    height: 10vh;
}

.container {
    border: solid blue; 
}

<header>
    <nav class="navbar navbar-expand-md navbar-dark bg-dark fixed-top">
        <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">
            <span class="navbar-toggler-icon"></span>
        </button>
        <a class="navbar-brand" href="#" data-placement="right" data-animation="false" data-toggle="tooltip" title="Aller à Mes Summaries">My Logo</a>
    </nav>
</header>

<!-- Begin page content -->
<main role="main" class="container">
    <div class="row mt-3" style="border: solid green">
        <div class="col-sm-12 col-md-3" style="border: solid red; height: 200%;">col</div>
        <div class="col-sm-12 col-md-5">col</div>
        <div class="col-sm-12 col-md-4">col</div>
    </div>
</main>

<footer>
    <nav class="navbar navbar-toggleable-md navbar-inverse bg-dark h-100"></nav>
</footer>


<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta.2/css/bootstrap.min.css" rel="stylesheet"/>

To update your markup from alpha 6 to beta 2 you have to make the following changes: rename .navbar-expand-md to .navbar-expand-md, .navbar-inverse to .navbar-dark and .bg-inverse to .bg-dark.

Revisiting this question using the newer Bootstrap 4.4.x class (no extra CSS needed)

<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>

The result is a full-height layout header/nav, footer, and scrolling main content area in the middle. The footer is always at the bottom regardless of page height.

Check the snippet. I fix your code and I change html. At this point main content should be fixed position and footer should be fixed height.

// Initialize tooltip component
    $(function () {
        $('[data-toggle="tooltip"]').tooltip()
    })

    // Initialize popover component
    $(function () {
        $('[data-toggle="popover"]').popover()
    })

main{
  height: calc(100% - 54px - 30px); /* Height should 100% - header height - footer height */
  left: 0;
  overflow-x: hidden; /* If you need scrollbar */
  overflow-y: auto;/* If you need scrollbar */
  position: fixed;
  top: 54px; /* Header height */
  width: 100%;
  z-index: 1;
  background-color: #f5f5f5;
  border: 5px solid #ff0000;
}
