The issue can be observed here:
It doesn't work on emulated ie7 (ie9 -> developer tools).
I tried with many css settings, but probably not with all of them, as I believe there is some solution for this bug.
Jashwant's answer is essentially correct - what you're seeing is IE using the IE7 browser mode with IE9 document standard, in a real IE7 browser the Facebook Like button appears OK. The problem is with the IE developer tools.
When you first open the developer tools, they will display IE9 browser and document mode. If you change the Browser Mode to IE7, the Document Mode appears to automatically change to IE7 standards. However, if you then change the Document Mode to IE9, then back to IE7, you'll find that the Facebook Like buttons now display correctly.
Its in quirks mode. Apply a proper doctype.
And if you using developer tools,
Change document mode to ie7 standards

I'm working on a legacy system that has a mishmash of browser dependent features (don't ask). The plan is to revamp everything to be current, but in the meantime, I need to figure out a way to make the following happen:
If the user has Browser Mode set to compatibility mode for this site or in general, I need to make the Document Mode IE8. This specific case I'm looking into, I'm using IE10. When you switch to IE10 Compatibility mode, the "page default" for the Document Mode is Internet Explorer 7. If I could just make the page default Internet Explorer 8, I think that would solve my case for now.
When I try to use in the header, it ALWAYS forces to IE 8 compat mode.
I realize this is a very strange way to do things, and it's only temporary until I can properly fix the insanity....
Which IE8 mode do you want? IE8 Standards mode or IE8 "use the <!doctype>" mode? If the former, set x-ua-compatible to IE8. If the latter, set it to EmulateIE8. (The various options, in gory detail, can be found here.
(The first value specifically chooses IE8 standards mode as the target mode; the second will pick IE8 standards mode if the page contains a standards mode <doctype> or IE5 quirks mode if the page doesn't contain a <doctype>.)
The key is knowing which legacy document mode that you need for the page. Figure that out and target that mode specifically. (Use the Emulation tab of the Developer Tools to switch between modes until you find the one that works.)
Note that if you deploy the page to an Intranet (right click, choose Properties, and then check out the Zone value), you may wish to add a Mark of the Web to the page so that it opens in the Internet zone and avoids the various defaults that behave otherwise.
I would like to ask, why IE11 does not displays border-radius, justify-content and align-items in my project.
When I create new .html page these tags are supported. But not in my project. Can you please help me how to solve it? Mozilla Firefox display it right and the DOM explorer gives me no error messages.
Internet Explorer 10 and 11 use a squiggly red underline to indicate invalid rules.
Obviously, these are valid rules so referencing this article by John Schneider
When I looked at the CSS styles in use on the page in IE11’s built-in F12 developer tools, I noticed that the border-radius property on my form’s enclosing div was present, but it was missing its enable/disable checkbox, and the name of the style was shown with a red squiggle underline, as though IE didn’t recognize it. It seemed almost as though IE11 was behaving like a legacy browser that didn’t recognize that newer CSS property.
In fact, that did turn out to be exactly the problem. IE11 was rendering the form (running on my local IIS) with its legacy “Compatibility View” engine, which it is by default configured to do for intranet sites. (Oddly, my IE11 was not using Compatibility View to render another copy of the form that I was trying to use to debug the issue that I had IE loading via the “localhost” domain, which had me confused for a while.)
The solution was to disable IE11’s Compatibility View for intranet sites by doing Setting (gear icon) > Compatibility View Settings > uncheck “Display intranet sites in Compatibility View” checkbox. Making that configuration change immediately got IE11 to start rendering the page properly.
Your browser may be in compatibility mode to an older browser.
Press F12 - and check which version it's using.
When i am checking my code with the developer tools (F12), I have seen the option Compatibility view only in IE browsers. Why don't other browsers have this compatibility view mode?
I am confused about this. Can you guys clarify, is there any specific reason for this?
Because IE is the only mainstream browser which was so screwed up in its rendering that developers had to specifically work around IE problems and deliver alternative versions of their pages just for IE. The "compatibility mode" switches between the newer standards compliant mode and the older screw-up mode.
Other browsers don't have it because they've never had an alternative screw-up mode.
As for I know, IE mostly have compatibility issues with the older versions, That's why this option is provided by Microsoft. Moreover, very soon IE will be part of history as Microsoft is launching it all new web browser Microsoft Edge. http://en.wikipedia.org/wiki/Microsoft_Edge
I found a lot of links that said adding
<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" />
or an older version of DOCTYPE forces the browser into compatibility mode. But after repeated attempts with many combinations, seems to me that all it does is alter the Document Mode and NOT the Browser Mode
I bet if you just remove your DOCTYPE tag completely or make it invalid that IE will be forced into compatibility view. Broken markup of some sorts will force this mode. However, this will surely have other negative consequences for non-IE browsers.
You would like to force IE into compatibility mode?
Also, I don't believe IE will display compatibility mode in the console window.
Are you sure you don't mean quirks mode?
The browser mode function (as I understand it) in IE isn't exactly compatibility mode.
I'm just going to copy/paste from the official documentation below.
Browser Mode
Description
IE9
IE9 reports a UA string, version vector, and document mode to match the default browser behavior, which is the most standards-compliant mode in IE9. Use this mode to test how IE9 users experience your site.
IE9 Compatibility View
IE9 reports a UA string, version vector, and document mode, as if it is IE7; however, the UA string also includes the Trident/5.0 token indicating that the browser is really IE9. Use this mode to test how IE9 users experience your site if they click on the Compatibility View button.
IE8
IE9 reports a UA string, version vector, and document mode as if it is IE8. Use this mode to test how IE8 users experience your site.
IE7
IE9 reports a UA string, version vector, and document mode as if it is IE7. Use this mode to test how IE7 users experience your site.
The only way to force this to change no matter what, is to set it on the virtual directory level through IIS in the 'HTTP Headers' section of the properties menu. Changing it here will force the browser into whatever mode you set it to, 100% of the time.
Changing the setting here overrides whatever browser mode is specified at the web page level.
You can't. The Browser Mode is intended to be used by developers to see what their browser would look like with new features disabled (for instance, if I put my IE10 into the IE8 Browser Mode, it will no longer support border-radius, or anything else that was added).
Since it's a developer tool, there is no need for it on the regular user's side.
The Document Mode, on the other hand, involves how the document is rendered, not how it is supported. I can have my document in IE8 mode and still have rounded corners because the browser mode supports it.
That being said, you should ALWAYS use this:
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
If I see a site with a X-UA-Compatible header that contains anything else, I assume that the developer is a lazy bastard.
Is it still worth using the traditional input element for buttons or can I start to use the HTML5 button right away?
I have been able to verify that the button element works on the following, but are there any issues that I need to be aware of?
IE9 (3 modes from F12 tools)
IE9 with IE9 standards
IE8 with IE8 standards
IE7 with IE7 standards
Chrome 13
Firefox 4
Safari 5
Note: I am not supporting IE6-, I am interested in IE7+, Chrome, Safari, FireFox, Opera, etc.
I say use the button element as you then also get free accessibility via the keyboard with it, which can be handy.
Plus if it's a button, use the element that's made for it!
