The key to create IE specific styling is called 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
