If you read this blog, there is a 99% chance you've had a hair-pulling experience with IE. But if you are worth your salt as a CSS coder, you should be able to deal with it. I am of the opinion that you can handle anything IE can throw at you without the use of hacks. Hacks are dangerous, since they are based on non-standard exploits, you can't predict how they are going to behave in future browsers. The tool of choice for fighting IE problems is the conditional stylesheet. IE provides comment tags, supported all the way up to the current IE 8 to target specific versions, as well as greater-than/less-than stuff for targeting multiple versions at once.
Why use conditional stylesheets?
- You got problems, they need fixin'
- Keeps your code hack-free and valid
- Keeps your main stylesheet clean
- Perfectly acceptable technique, sanctioned by Microsoft
And remember, these conditional tags don't have to be used only for CSS. You could load JavaScript, or even use them down in the content of your site to display special IE-specific messages.
The Code
This would go in your <head> with all the other regular CSS <link>ed CSS files. The opening and closing tags should be familiar, that's just regular ol' HTML comments. Then between the brackets, "IF" and "IE" should be fairly obvious. The syntax to note is "!" stand for "not", so !IE means "not IE". gt means "greater than", gte means "greater than or equal", lt means "less than", lte means "less than or equal."
Note that IE 10 and up DO NOT support conditional comments at all.

Universal IE 6 CSS
Dealing with IE 6 and below is always an extra-special challenge. These days people are dropping support for it right and left, including major businesses, major web apps, and even governments. There is a better solution than just letting the site go to hell, and that is to serve IE 6 and below a special stripped-down stylesheet, and then serve IE 7 and above (and all other browsers) the regular CSS. This is been coined the universal IE 6 CSS.
<!--[if !IE 6]><!--> <link rel="stylesheet" type="text/css" media="screen, projection" href="REGULAR-STYLESHEET.css" /> <!--<![endif]--> <!--[if gte IE 7]> <link rel="stylesheet" type="text/css" media="screen, projection" href="REGULAR-STYLESHEET.css" /> <![endif]--> <!--[if lte IE 6]> <link rel="stylesheet" type="text/css" media="screen, projection" href="http://universal-ie6-css.googlecode.com/files/ie6.0.3.css" /> <![endif]-->Hacks
If you must...
IE-6 ONLY
* html #div {
height: 300px;
}IE-7 ONLY
*+html #div {
height: 300px;
}IE-8 ONLY
#div {
height: 300px\0/;
}IE-7 & IE-8
#div {
height: 300px\9;
}NON IE-7 ONLY:
#div {
_height: 300px;
}Hide from IE 6 and LOWER:
#div {
height/**/: 300px;
}html > body #div {
height: 300px;
}Argument against conditional stylesheets
We shouldn't need them. They are against the spirit of web standards.
