推荐答案

如果在 .columns-container 的声明中添加 text-align：center 然后它们集中对齐：

If you add text-align: center to the declarations for .columns-container then they align centrally:

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

，但需要将 .column 元素重置为 text-align：left （假设您 左对齐，显然（ JS Fiddle demo ）。

This does, though, require that you reset the .column elements to text-align: left (assuming you want them left-aligned, obviously (JS Fiddle demo).
