• Correct the HTML or CSS for the webpage.
• Set the X-UA-Compatible item through the Meta tag or the HTTP header to force a rendering mode.
• Use the client-side Internet Explorer 7 Compatibility View mode

Back to the top

1. You add a hostname.tld or hostname to the Quirks policy list. For example, you add Microsoft.com or MyWebServer (netbios name). In this case, all webpages that are displayed in Quirk mode reference primary hostname.tld or hostname.
2. You have to send the Meta tag or the HTTP header to override Quirks mode policy list for a hostname or a hostname.tld for particular websites or webpages that should not be displayed in Quirks mode.
   
   Note There is an order of precedence that has to be observed when you use the Quirks mode policy list:
   1. The presence of the X-UA-Compatible item in the Meta tag or the HTTP header overrides Internet Explorer 7 Compatibility View and Quirks Compatibility View.
   2. Internet Explorer 7 Compatibility View overrides Quirks Compatibility View.
   3. Quirks Compatibility View overrides the Intranet zone. By default, the Intranet zone displays all websites in Internet Explorer 7 Compatibility View.
   4. If the website uses the Intranet Zone and none of the above is true, the webpage will be displayed in Internet Explorer 7 Compatibility View.
3. Sub-domains are not supported with the Quirks mode policy list. The same is true for the Internet Explorer 7 Compatibility View mode.
