Question

我有一个<h2>元素，我希望将所附文本垂直居中。它在桌面Chrome上看起来是正确的，但在移动设备（iOS）Chrome上却看不到。我非常感谢对此问题的任何见解。下面是两个（桌面优先，移动秒）屏幕截图的链接：

Desktop (correct behaviour). Mobile (incorrect behaviour).

HTML和CSS代码包含在下面。为了便于阅读，我缩写了HTML代码。非常感谢，互联网！

HTML：

...
<body id="home">
<div id="main">
    <div id="header">
        ...
    </div>
    <div id="content">
        <img src="i/splash.jpg" alt="" id="splash" />
        <div id="inner">
            <h2>hi!</h2>
            <p>Lorem ipsum...</p>
        </div>
    </div>
    <div id="clear"></div>
    <div id="footer">

Answer 1

我认为，问题在于，移动浏览器会调整font-size的大小。这不是一个好习惯，但你可以通过使用：

来避免这种情况

html {
    -moz-text-size-adjust: none;
    -ms-text-size-adjust: none;
    -webkit-text-size-adjust: none;
    text-size-adjust: none;
}

Answer 2

使用em进行字体大小调整 - 这会针对不同的窗口大小正确调整

#inner h2{
font-size: 1em
}

（例如）

Answer 3

我已经检查了多个浏览器（网络/移动设备）。一切都对我很好。但是，您可能遇到3个问题 -

1）字体问题

2）移动网络调整大小问题，如果不是流畅的布局。

3）缓存集
