Are IE8's Development Tools Browser and Document Modes the same as using IE7

Question

In Internet Explorer 8 when I bring up the Developer tools window (F12), it gives you the option to change browser mode and document mode. I am need to test some scripts to see if they will be fine in IE 7 which is what my client runs on, but I only have IE 8 on my machine.

If I set Browswer Mode to IE 7 along with IE 7 standards for document mode is this the same as if I were to open my pages in the IE 7 browser? ？

Answer 1

Nothing will be the exact same unless you really use IE7. However the differences are pretty insignificant and usually pretty low level or so specific, that 99% of the users (and even developers) will never notice or face them.

However you might want to install this tool as well. It's handy to have all those IE-s in one place for testing purposes.
