I'm seeing some really strange css float behavior in IE and I'm trying to diagnose the issue. Is there an equivelent to Firebug or Chrome's "Inspect Element" in IE?
How do you typically debug CSS positioning issues in IE?
There are a couple of options available, IE8 has a decent developer toolbar built in, you can access it by pressing F12 or if not going into the options menu and using developer tools, it doesn't work as well as firebug, but once you are able to select an element, you can easily change the styles. Firebug lite is another option though I havent used it in IE.
Have you tried firebug lite?
IE9 has got great debugger, check it out. You can also set compatibility mode to IE8 or IE7 if you want.

in firefox I can usee firebug, in chrome I can use the css console. Both to make live changes to css for troubleshooting purposes. However I do not know of a way to do this in IE, which is where I have the most css issues.
So, whats the best way to troubleshoot css issues in IE?
Thanks!
Use the IE Dev Tools (video).
And here for more links and information.
They are built into IE 8 and can be invoked by F12.
If you like using Firebug, give Firebug Lite a try.
Edit: In case it's not clear, Firebug Lite is for any browser. It is created with JavaScript, it is not an extension/plugin.
This makes CSS debugging easy on IE7 and even IE6.
IE Developer tool .. if you are using IE8 .. just hit F12
or
click Tools -> Developer Tools
The most popular for IE is:
Internet Explorer Developer Toolbar
IE Developer Tools http://msdn.microsoft.com/en-us/library/dd565627%28v=VS.85%29.aspx
So I do quite a lot of CSS development, and I work with Firefox / Firebug A LOT. I generally know how to debug for IE6/IE7 (as far as techniques) and if I have the source, I can easily just edit the actual files and run a local server on a linux machine and test it in IE, going back and forth until it's fixed.
I find myself lately being asked to debug problems in IE6 when I don't have the source. Is there anyway to emulate a firebug like flow in IE6?
Firebug Lite doesn't allow you to change css values, nor does IETester. It doesn't necessarily have to be an inline tool (maybe there is some utility to quickly download 1 off webpages and their dependencies), but I'm definitely looking for the most productive solution to fixing bugs in IE when I don't have the source readily available to me.
Try the IE Dev Toolbar.
It's not as convenient or user-friendly as Firebug, but it can modify CSS and HTML attributes.
Firebug Lite is the best way to debug html in IE.
Firebug is an extension for Firefox,
but what happens when you need to test
your pages in Internet Explorer,
Opera, and Safari?
The solution is Firebug Lite, a
JavaScript file you can insert into
your pages to simulate some Firebug
features in browsers that are not
named "Firefox".
Firebug Lite creates the variable
"firebug" and doesn't affect or
interfere with HTML elements that
aren't created by itself.
Since you already know about it and it doesn't fit what you need, take a look at DebugBar. There is also a MS solution with Internet Explorer Developer Toolbar.
you have tryed Internet Explorer developer toolbar
Why, the IE developer toolbar of course!
It allows manipulation of HTML and CSS values.
3 solutions which i use always
Use IE 8 with developer toolbar in IE 7 emulation mode to solve problems of IE 7 and for IE 8 use in normal mode
for IE 6 it's best till date for me i use this a lot http://www.paciellogroup.com/blog/?p=7
and this to judge right selectors it's very good http://www.westciv.com/mri/ ( i use this for all browser, because it can tell perfect selector for element )
Firebug lite and IE developer toolbar on IE7 not much useful
Are there tools other than Firebug Lite that might help one get into Internet Explorer's buggy little mind and find out precisely where and why it's mangling my CSS so badly?
Firebug Lite is a useful tool of course, but it seems to be missing the crucial feature (present in the 'full' Firebug plugin) that allows you to see which parts of which declarations are ignored in favor of other declarations.
For example, using Firefox with Firebug I can see that .foo {color: red} is overridden by .bar {color: blue} later in the stylesheet.
But, Firebug lite only seems to show the final, calculated style -- I can't tell which declarations are being ignored, which are being overridden, which aren't supported at all, and which are just plain buggy.
Is there another tool that might be helpful here?
I am using IE8 Developer Tools (which is included out of the box), it can show style tracing.
IE7 have also Microsoft-supplied add on called IE Dev Toolbar. Have not used this extensively though.
What version of IE are you using?
Yes. In IE8 hit F12. In previous versions, install this.
The developer tools included with IE8 works quite well.
I have found jQuery to be helpful in figuring out what's going on "under the hood" so to speak. For instance, I had a situation recently where I found that I could not trust the Developer Tools that come with IE 8 (which, by the way, I was running in IE 7, standards not quirks, compatibility mode. Some CSS properties declared in the stylesheet were not being shown as computed, in addition to other IE-strangess I was experiencing. So, I just threw some javascript on the page, including jQuery, which would allow me to type up some code and have it evaluated without relying on IE Developer Tools, Firebug or the Web Inspector in Safari. You can evaluate statements like:
$('body').css('background-image');
which might return:
'/images/default_background.png'
or whatever.
YMMV, but it's worth the time to try it.
I don't know if it has the ability to check specific css overriding, but I'd start out the Internet Explorer Developer toolbar
Another one is the Debug Bar. Works in IE 7 or 8; and is similiar to Firebug
You can use my new tool to view the layout of any element you can mouse over.

I am a CSS newbie. Is there a tool that can help debug CSS styles applied to a web page.
How does one generally debug CSS and resolve issues when some elements on the page are not appearing as they should? For now, I have to painfully comment out CSS declarations one by one to understand how the styles are getting displayed.
By browser:
Firefox there is a plug in module called Firebug. It is easy to install and very powerful. It is even better when combined with 'Web Developer' for Firefox.
Internet Explorer has a Developer Toolbar, which is not as good as Firebug but good enough to check things still work in IE. Additionally there is a tool called IE DOM inspector. There is also a version of Firebug for IE caled Firebug Lite.
Google Chrome comes with built in tools similar to Firebug. See the 'tools->developer' option in the pull down menu to the right of the address bar. This allows you to see the css rules used by each element. It also has Javascript debugging support.
Safari uses a tool called Web Inspector.
Opera has a built-in utility called Dragonfly.
You use Firebug in Firefox, which makes debugging a lot more easy.
And built-in DragonFly in Opera.
You can use the Firebug plugin for Firefox. It is very useful for CSS.
You can dynamically switch on and off styles and fields from styles. It is great.
If you're not using Firefox you can now get Firebug Lite which you can use in IE etc.
Web developer tools like Safari’s Web Inspector or Firebug for Firefox can help you to debug your CSS. Those tools can show you the rule cascade applied to a specific element and allow you to change or disable particular properties.
Use Firefox to develop and test your CSS first, then switch to other browsers to test your code. This is a generally accepted method IMHO.
Firebug is great, but it works even better if you combine it with Web Developer plug in for FF.
There is a great site, worth checking out, with lots of info about CSS and HTML development.
When you need to debug IE - specific problems. I've heard people telling IE DOM inspector is not too bad. You can also try tools described in this post.
Now you can use my newly released tool for this in most modern browsers!

I have an ASP.NET page where I need to figure out where the style for a textbox is coming from. There are several style sheets defined for the page and I want to be able to use some sort of tool / editor that will tell me what styles were used and from what file(s) to render the textbox.
Thank you.
Use Firefox with Firebug and inspect the Text-box. Firebug is the most useful tool to do exactly that.
In IE you can use the IE Developer Toolbar. But I'm a fan of FireBug for FireFox.
From comments: Bernard Chhun recommended FireBug Lite as an alternative to IE Dev Toolbar. It also works for Opera and Safari too.
Most browsers have developer tools (build-in or as extension) that can show you the cascading order of the applied rules.
For Firefox there is the Firebug extension, Safari (WebKit) has Web Inspector, Opera has Dragonfly and for the Internet Explorer there is the Internet Explorer Developer Toolbar.
The web developer toolbar for Firefox has CSS and element inspectors which I find very useful.
You can also modify the CSS in the browser so you can tweak layout without going back to your IDE
