页脚文本和垂直对齐问题

Question

我试图让页脚文本在页脚DIV内垂直居中，但这并不起作用。我尝试了vertical-align: middle，但没有成功。问题出在哪里？非常感谢。 JSfiddle：http://jsfiddle.net/Grek/hqdP2/

CSS（层叠样式表）：

/* Footer

    width: 100%;

    line-height: 1;
    letter-spacing: 0.10em;
    text-transform: uppercase;
    padding-bottom: 1px;
}
.footer p.right {
    display: inline-block;
    float: right;
    padding-right: 20px;
    color: #fff;
    padding-left: 20px;
    vertical-align: middle;
    font-family: 'Futura W01 Heavy', Arial, sans-serif;
    font-size: 10px;
    line-height: 1;
    letter-spacing: 0.10em;

Answer 1

我会对你的CSS进行以下调整：

.footer {
    height: 50px;
    line-height: 50px;
    vertical-align: middle;
}

.footer p.left {
    xxvertical-align: middle;
    xxline-height: 1;
}
.footer p.right {
    xxvertical-align: middle;
    xxline-height: 1;
}

在你的 .footer 中声明 height 和 line-height 为一些固定值。在 p.left 和 p.right 中删除这两个属性。只要内容是单行的，这样做就可以了。

Answer 2

你的.footer p有一个底部边距。可以使用上下边距覆盖它，例如：

.footer p {
    margin: 10px 0;
}

Answer 3

一种可能的解决方案是调整.footer p.left和.footer p.right中line-height的值。例如，line-height: 2.0em将基于您现有的示例垂直对齐。或者您应该在.footer中设置一个height，并使.footer p.left和.footer p.right中的line-height等于.footer中的height。
