The conditional statement is contained within square brackets, and begins with if followed by an expression. The enclosed HTML content is delimited by the opening statement. In the example above, the enclosed HTML content??”a tag??”will be revealed to all IE browsers that support conditional comments. It links to a style sheet that only IE will see. All browsers other than IE versions 5 and later will see the code above as one simple HTML comment. If we remove the brackets and text for the sake of clarity, we??™re basically left with a normal comment structure as follows: link href="iecss.css" rel="stylesheet" type="text/css" > --> Conditional Comment Operators As we mentioned already, we can use conditional comments to apply CSS rules to specific IE browser versions with the help of comparison operators that allow each version of IE to be targeted precisely. We can write complex expressions using one or more of the operators listed in Table 17.
