引導4 - 山坳垂直對齊工作不正常

讀取引導文件，你可以得到的alignment examples section.引導4 - 山坳垂直對齊工作不正常

它告訴你可以使用使用Flexbox的對齊工具來垂直和水平對齊列作爲引導CSS類align-items-start，align-items-center和align-items-end，但是當我嘗試它的內容與全高container預期的那樣垂直對齊，請看下面的代碼：

html, 
 
body { 
 
    height: 100%; 
 
} 
 

 
.fill { 
 
    min-height: 100%; 
 
    height: auto !important; 
 
    height: 100%; 
 
    background-color: lightblue; 
 
} 
 
.col { 
 
    border: 1px solid red; 
 
}

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.6/css/bootstrap.min.css" integrity="sha384-rwoIResjU2yc3z8GV/NPeZWAv56rSmLldC3R/AZzGRnGxQQKnKkoFVhFQhNUwEyJ" crossorigin="anonymous"> 
 

 
<div class="container fill"> 
 
    <div class="row align-items-start"> 
 
    <div class="col text-center"> 
 
     align-items-start 
 
    </div> 
 
    </div> 
 
    <div class="row align-items-center"> 
 
    <div class="col text-center"> 
 
     align-items-center 
 
    </div> 
 
    </div> 
 
    <div class="row align-items-end"> 
 
    <div class="col text-center"> 
 
     align-items-end 
 
    </div> 
 
    </div> 
 
</div> 
 

 
<!-- jQuery first, then Tether, then Bootstrap JS. --> 
 
<script src="https://code.jquery.com/jquery-3.1.1.slim.min.js" integrity="sha384-A7FZj7v+d/sdmMqp/nOQwliLvUsJfDHW+k9Omg/a/EheAdgtzNs3hpfag6Ed950n" crossorigin="anonymous"></script>

我預計將有在container底部的垂直中間align-items-center內容和align-items-end。

我做錯了什麼或我誤解了什麼？

爲了垂直對齊flex-container中的項目，您需要將height設置爲flex-container。

.row{ 
    min-height:100px; 
}

html, 
 
body { 
 
    height: 100%; 
 
} 
 

 
.fill { 
 
    min-height: 100%; 
 
    height: auto !important; 
 
    height: 100%; 
 
    background-color: lightblue; 
 
} 
 
.col { 
 
    border: 1px solid red; 
 
} 
 

 
.row{ 
 
    min-height:100px; 
 
}

    <div class="row align-items-start">

     align-items-start 
 
    </div> 
 
    </div> 
 
    <div class="row align-items-center"> 
 
    <div class="col text-center"> 
 
     align-items-center 
 
    </div> 
 
    </div> 
 
    <div class="row align-items-end"> 
 
    <div class="col text-center"> 
 
     align-items-end 
 
    </div> 
 
    </div> 
 
</div>
