Whenever anyone says they have "cross browser issues", they almost always mean "it doesn't work in IE". Frequently, the developer uses IE as their reference for how things work which is the worst thing they could do since IE is 13 years behind all other browsers in modern standards and compliance and inept at best.
每当有人说他们有“跨浏览器问题”时，他们几乎总是指“它在 IE 中不起作用”。通常，开发人员使用 IE 作为他们工作原理的参考，这是他们能做的最糟糕的事情，因为 IE 在现代标准和合规性方面比所有其他浏览器落后 13 年，而且充其量也无能为力。
Therefore, always use a modern browser (anything but IE) to initially test your markup. Along with validation of HTML and CSS, this will make your code work everywhere in most cases. Then you know your code is written correctly. As you go along, look in IE to see how it screws everything up but the quirks and bugs of IE are well known, as are the hacks to fix it.
因此，始终使用现代浏览器（IE 除外）来初步测试您的标记。随着 HTML 和 CSS 的验证，这将使您的代码在大多数情况下无处不在。然后你知道你的代码是正确编写的。随着您的进行，在 IE 中查看它是如何搞砸一切的，但 IE 的怪癖和错误是众所周知的，修复它的技巧也是如此。
Never, ever trust IE to do anything right. Do NOT fall for the fallacy that IE9 will be any savior either.
永远，永远不要相信 IE 会做正确的事情。不要误以为 IE9 将成为任何救星。

there are 2 possibilities when it comes to cross-compatibility:
在交叉兼容性方面有两种可能性：
- handle cross-compatibility by yourself -> this is almost impossible for non-experts (keep in mind that you have to know how every browser is interpreting HTML/CSS/JS)
- use a javascript library like:
the library will handle cross-compatibility ;)
该库将处理交叉兼容性；)

对于 IE，你可以使用这个小技巧..：
<!--[if IE]>
<link rel="stylesheet" type="text/css" href="file.css"/>
