Answer 1

あなたが.columns-containerの宣言にtext-align: centerを追加した場合、彼らは中央で揃える：

.columns-container { 
    display: table-cell; 
    height: 100%; 
    width:600px; 
    text-align: center; 
}

    <footer class="section"> 
 
    bar

</div>

これは、.column要素をtext-align: leftにリセットする必要があります（と仮定すると、は左揃え、明らかに（JS Fiddle demo）とします）。

ただ、将来の訪問者のためにあなたのCSSに

ショートスニペットをこのクラスを追加 - 水平テーブルのセル（+垂直）

html, body { 
 
    width: 100%; 
 
    height: 100%; 
 
} 
 

 
.tab { 
 
    display: table; 
 
    width: 100%; 
 
    height: 100%; 
 
} 
 

 
.cell { 
 
    display: table-cell; 
 
    vertical-align: middle; 
 
    text-align: center; /* the key */ 
 
    background-color: #EEEEEE; 
 
} 
 

 
.content { 
 
    display: inline-block; /* important !! */ 
 
    width: 100px; 
 
    background-color: #00FF00; 
 
}

<div class="tab">
