Some of my users a reporting that my page does not render correctly in their IE browser. What could be the cause?
If your page look fine in IE normally, you can usually get that broken presentation by switching IE to "Compatibility Mode", which is usually reserved for viewing pages with older non-standards based markup and CSS. Since your page is perfect in normal, standards-based mode you really want to prevent users form being able to switch into Compatibility Mode. Fortunately Microsoft has made this easy by proving a simple <meta> tag that you can add to your page(s).
In Code View, Copy and Paste this into the <head> region of your page, usually right after the <title> tag:
<meta http-equiv="X-UA-Compatible" content="IE=Edge" />
This tag will assure that all IE browsers render your page in modern standards-based mode regardless of the users browser settings.
