You who said that IE should be the main concern for testing on : you're absolutely Wrong dude !!!
I am actually coding another but small website of mine. I do not use dreamweaver anymore: I use only open-source syntax highlighters, such as jEdit or the excellent "programmer's notepad" (or notepad.exe ^.^) because I learned the code enough. and testing on the layout view of Dreamweaver is a bad idea. Visitors won't open your website with Dreamweaver.exe =D (his layout rendreing is based on IE's i think)
But testing on IE is even worse.
One only throws html-tag soup garbage and proprietary code out there and it works fine.
Result: we have within all IRC and Forums complaining about websites uncorrectly viewed on Firefox. It's the opposite: YOU are the one who did retarded code that works fine in IE, because IE is retarded.
I'll return to what I first said: I am actually making this website, and you know what? I have Opera, Firefox and IE open at the same time, and refresh the page each time I add a line of html or especially Css.
I know it wastes time, but you keep on track of every change that will happen, so that you can correct a "bug" if it happens cause you know the modification you did for that to happen. So you end up gaining so much time amongst other things.
In this website, I did sth different: I tested only in Opera and FF. the small bugs that I had, was only concerning differences between margin/padding on absolute or fixed blocks. anyway. The website was perfect on both different browsers (=different layout engines

and when I opened the webpage on IE waiting for real-world bugs to appear, and wasn't surprised.
After a bunch of tricks that did not work, I thought I would just ignore IE and design the site for modern browsers only, but i said to myself: professional webdesigners spend valuable time caring about IE, so I decided to do that too, even if it's only a small very personal website.
I unlinked the main stylesheet, and started making a new one for IE (to appear and function as on FF+OPR). Finally, with the help of Dean Edwards' extraordinary scripts that enable position:fixed and CSS2 selectors and pseudo selectors, and while rebuilding the whole stylesheet, I made it work 99.5% like on FF+OPR, which I am very proud of.
Linked the special stylesheet for IE using conditional <!--comments--> (without ignoring the CSS' cascade system) . that's all.
"The only reason I test in IE is because I tend to use it more often" - So funny man!! Do _you_ make a website for yourself ? ;D
"No matter how much you deny it, IE MUST be your primary concern when testing, since it's still most used browser" - No way mister. If webdesigners (especially advanced ones) keep on doing that, then we won't have any web standards anymore. If you were able to design real web standard compliant websites, you would have appreciated them, and respected them so much, and hated IE forever: preceding, actual and future(?) versions =D
Besides, you say that IE7 is standards compliant: Hahahaahahah !!
IE7 will be just like a patch to IE6 that hasn't been updated (standards-speaking) since 99's. Especially Css support. But not everything, far less.
Even, IE7 won't support the MIME type required for files coded as XHTML 1.1, the application/xhtml+xml, and IETeam is saying it proudly on their PR
weblog, proudly.
What make me laugh so hard even more, is that IE7 will somewhat have a bit of Css suport fixed, that most websites (tested in IE) will BREAK in IE7. Yes! That's awesome.
"IE7 Beta 3, even though only beta still, is way superior to FF in every way (speed, security, JS support) and is W3C compliant." - IE7 is not standards compliant. and as much as secure it will be, it will be CERTAINly brought down. unlike FF and Opera. FF is constantly updated with security fixes.
then, if you're saying that IE is fast, I do agree, but only in program loading, not webpage rendering or browsing. It is logical, since it is embedded and part of Windows OS. while FF is Not. But FF is far more speedy in web browsing and in STANDRADS compliance.
Wait a second, ain't I using Opera? yes, and it is the best browser ever. and the fastest too ; ).
you Really should see this. Really.
Opera, on each update, doesn't fix its program, bnut adds features.
Opera 9 actually has (without speaking of the browser):
*Rss support (very good, compared to FF's)
*email client
*IRC client
*widgets
*newsgroups
*bittorrent DL
*content blocking
*voice controls and mouse gestures
*restoring all tabs (+history) after an eventual crash
*zoom text + images
*fit to window width : for annoying horizontal scrolls ; D
*ability to undisplay images on websites
*site preferences ......
etc. etc.
Really: What else do you still want?
I'm a real Opera fan I must admit.
I have come to an end of this reply, hope it was useful.
oh no I forgot; Opera is the REAL standard browser also, because it has fully passed the
Acid2 test. Check out the test result in IE6 LOL!!
I have come to an end this time, and it is the last time i'm saying this.
So, well, see ya
