I think, it is good to learn CSS and create site for all browsers. In other hand like admin you have right to do whatever you want on your site. I am thinking little bit about problem and, in that situation, I will do something like that:

<style type="text/css">
<!--
.whatever{  
display : block;
}
-->
</style>
<!--[if IE]>
<style type="text/css">
.whatever{  
display : none;
}
</style>
<![endif]-->

<div class="whatever">This site is created for best preview in IE browsers. </div>

In that case users with non IE browsers will get simple message how their browser maybe will not produce the best preview.

Wow, so you want to block 25% of your visitors?

Okay then.

Google "PHP browser recognition", and then use that PHP code to find and ban anyone who uses Firefox.

Edit: Actually, Shivaji's post above does it best. Although just a quick thing: the display: ; elements are the wrong way around.

You'd actually want to do "display: none;" to everyone, but then do "display: block;" only to those using IE

I am no expert for sure but it looks like Shivaji's code is correct.

If IE do nothing and if not IE display this message.

He isn't blocking them. He is warning them.

Makes me wonder what the installed base of computers world wide would be if all you saw when you turned them on was the flashing C:\>

Somehow I think maybe there would be a lot less users.

Ah sorry, my bad! You are correct there

What I was thinking is that, with regards to the OP's original problem (i.e. he wants to block everyone who isn't using IE), they could do something like:

<style type="text/css">
<!--
body {
display: none;
}
!-->
</style>
<!--[if IE]>
<style type="text/css">
body{
display: block;
}
</style><![endif]-->

Although I wouldn't recommend blocking everyone but IE - for one, IE is an awful browser. We should be blocking everyone who uses it And secondly, at least 25% of people use Firefox and other browsers. Hence blocking all of these would be a huge mistake.

Are you sure ?
I was playing with MS-DOS 3.3 when my school was teaching word processing on Mac Plus and OS/2 computers.
And there where multiple other alternatives that where created at the end of the seventies, beginning of the eighties already:

http://en.wikipedia.org/wiki/Xerox_Star
http://en.wikipedia.org/wiki/Apple_Lisa

The industry is not where it is today because of Ms.
If Ms would not have filled that gap, another company would have.
They where at the right place at the right time, and made the right decision.
Nothing else.

If memory serves, it was like that: until MS copied Mac's "windowed" design... Then, years later, Vista would be known to copy Mac, yet again. If Mac's didn't have everything bound to their specific stuff and was more programmer friendly, then I'd be on one of them (well, probably Linux, but I just haven't gotten around to learning Linux yet and am not too sure about the GUIs available).

The GUI interface would have come along even if MS hadn't been the one to steal things first for the pc and Windows 3.0 was certainly no prize-winner. There's just no way you can say we'd have nothing if not for MS. One or more of the companies that MS stole from, 'acquired' or crushed might have been the dominant player instead. No way to really know who would have stepped up, but things would not have stayed a C:\> and if you want to split hairs, originally there was no C drive!

Hi
I would never dare to deny my website to 25% or more of the users of other browsers. But I see on many sites the warning about the site being best viewed in IE, and that would be better than just outright not show them the site
My opinion, of course.
Thanks

How well I recall using a tape recorder as a drive.

Delighted when I got the wife model* real PC.

*Not quite enough memory and two floppies.

Sorry. The devil made me do it.

Keep this thread alive! Let's go for three pages!

I find it interesting that the OP has not returned though. Obviously there's a general consensus that the idea is not a good one.

Idea is not good definitely. Users don't like blank pages. Some of them can report broken link if you have site submited in directories, etc.

Horrible idea! Optimize your site for multiple browsers ~!!~

It is sad but typically the longest threads with the most responses, feature authors who only post their initial question and probably never return.

I think the longest threads are usually in response to easy questions. People love to jump onto bandwagons. Look at me! Wheee! I'm riding! Keep the thread alive. Ok... stopping... really...
