How to change the ie browser mode as Quirks mode and what is Quirks mode?
In Internet Explorer press F12 and then change the document mode. Alternatively in IE you can press Alt Q.
Quirks mode is to allow you to develop for older browsers, i.e. I.E 6. Mainly for backwards compatibility.

How do you activate quirks mode only for IE versions below IE8 on a page where the doctype html5 is set? Or, is possible to interpret a piece of code in quirks mode?
It appears to be possible to achieve this by combining any HTML comment (<!-- anything -->) before the doctype (this triggers Quirks mode in IE6—9) and <meta http-equiv="X-UA-Compatible"content="IE=Edge"> (which has precedence over the doctype and triggers Standards mode in IE8—9). So only IE6—7 will have Quirks mode, and IE8+ and all non-IE browsers will switch to Standards mode.
I was wondering if there is a way that my IE10 browser would be set to Quirks Mode automatically when I open it? I'm using a windows 8 64-bit. I am accessing a site that needs to be in Quirks Mode and when I open my browser I still need to change it to quirks mode to be able to access the site properly. And when I restart my computer and open the browser again I have to set it again to quirks mode. And this is really tiring.
Thanks!
Specification of an IE rendering mode also applies to IE5 Quirks Mode. To run instances of a WebBrowser control in IE5 Quirks Mode, insert the following value into the registry:
[HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_NATIVE_DOCUMENT_MODE]
"iexplore.exe"=dword:C350
[HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION]
"iexplore.exe"=dword:C350

Obsolete Feature Controls
When a DOCTYPE isn't defined or is mispelled, etc. are the older IEs the only browsers that go into quirks mode?
Or does super old Firefox, Safari, etc. do this as well?
No, browsers generally have a quirks mode. Each browser has its own quirks mode, though they share some of the behavior. There have been attempts to specify what exactly happens in quirks mode (more or less making it defined behavior), but the current situation is a mess: if you do not use a doctype string that triggers “standards mode”, you will get different quirks on different browsers.

A short look into Wikipedia answers this...
For some reason that I can't make out, the player is defaulting to flash in IE, although it works just fine in Chrome and FF. I've added in all three recommended video formats (mp4, webm, and ogv).

Any help would be most appreciated!
IE 9 renders your page in quirks mode. While in quirks mode, IE can't play MP4 natively so the Flash fallback is needed.
If you open IE's developer tools (press F12) and switch the document mode from "Quirks" to "Internet Explorer 9 standards", you'll see the player on the reloaded page can now use the browser's native MP4 support.
Also try this in the console of developer tools. In quirks mode it will error because canPlayType is not a function.
document.createElement("video").canPlayType('video/mp4; codecs="avc1.42E01E, mp4a.40.2"');
See this question for how to coax Internet Explorer into using standards mode.
I have a project experience map that is generated by JetPhoto software... it's wonderful, and is exactly what I needed. Unfortunately, it seems to get stuck in IE9. If I tell IE9 to use "compatibility mode", all the pins load fine (like in every other browser). The portfolio is up here: http://www.aboutcis.com/experience/
Is there any way to tell IE9 to load the page in compatibility view for all users?
I'm not much for HTML (it's gotten so complicated compared to when I learned it), but I came across the following tag...
<meta http-equiv="X-UA-Compatible" content="IE=7">
Is this the intended use of this tag? Am I on the right track? Does anyone have a tip or idea that might help me understand how to overcome this? Is this a DOCTYPE issue maybe (which I understand nothing about)?
Thanks!
The syntax for compatibility mode is:
<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE9" >
The content attribute specifies the mode for the page; to mimic the behavior of Internet Explorer 7, specify IE=EmulateIE7. Specify IE=5, IE=7, IE=8 or IE=9 to select one of those compatibility modes. You can also specify IE=edge to tell Internet Explorer to use the highest mode available.
Understanding Document Compatibility Modes
Internet Explorer supports a number of document compatibility modes that enable different features and can affect the way content is displayed:
IE9 mode provides the highest support available for established and
emerging industry standards, including the HTML5 (Working Draft), W3C
Cascading Style Sheets Level 3 Specification (Working Draft),
Scalable Vector Graphics (SVG) 1.0 Specification, and others.
IE8 mode supports many established standards, including the W3C
Cascading Style Sheets Level 2.1 Specification and the W3C Selectors
API; it also provides limited support for the W3C Cascading Style
Sheets Level 3 Specification (Working Draft) and other emerging
standards.
IE7 mode renders content as if it were displayed in standards mode by
Internet Explorer 7, whether or not the page contains a <!DOCTYPE>
directive.
Emulate IE9 mode tells Internet Explorer to use the <!DOCTYPE>
directive to determine how to render content. Standards mode
directives are displayed in IE9 mode and quirks mode directives are
displayed in IE5 mode. Unlike IE9 mode, Emulate IE9 mode respects the
<!DOCTYPE> directive.
Emulate IE8 mode tells Internet Explorer to use the <!DOCTYPE>
directive to determine how to render content. Standards mode
directives are displayed in IE8 mode and quirks mode directives are
displayed in IE5 mode. Unlike IE8 mode, Emulate IE8 mode respects the
<!DOCTYPE> directive.
Emulate IE7 mode tells Internet Explorer to use the <!DOCTYPE>
directive to determine how to render content. Standards mode
directives are displayed in Internet Explorer 7 standards mode and
quirks mode directives are displayed in IE5 mode. Unlike IE7 mode,
Emulate IE7 mode respects the <!DOCTYPE> directive. For many web
sites, this is the preferred compatibility mode.
IE5 mode renders content as if it were displayed in quirks mode by
Internet Explorer 7, which is very similar to the way content was
displayed in Microsoft Internet Explorer 5.
Edge mode tells Internet Explorer to display content in the highest
mode available. With Internet Explorer 9, this is equivalent to IE9
mode. If a (hypothetical) future release of Internet Explorer
supported a higher compatibility mode, pages set to edge mode would
appear in the highest mode supported by that version. Those same
pages would still appear in IE9 mode when viewed with Internet
Explorer 9.
Because edge mode documents display webpages using the highest mode available to the version of Internet Explorer used to view them, it is recommended that you should only use this document mode for testing purposes only. Do not use it for production uses.
