How to debug css in IE?

Question

Is there a way to debug a css file in IE? I wish to see if a particular background-image is loaded or not.
This is in reference to the question:
extjs gridfilter icon not showing in IE but shows in Firefox

Answer 1

Do you want to target IE specifically in your CSS? If so I wrote a blog post about this not so long ago, please have a read: http://ajthomas.co.uk/blog/?p=299.

Answer 2

Or for any version of IE, try FireBug Lite. You can simply bookmark the link given on that page (bookmarklet) and then, to open a FireBug like thingy whilst on IE, simply click on the bookmark you just added.

Answer 3

Use the built in browser troubleshooting tool (aka Developer Toolbar) by pressing F12.

It is built into IE8 and later, but you can download and install it in earlier versions.
