An example of a conditional comment is shown in the following code block:
Anything placed inside this comment will only be shown in Internet Explorer 6??”all other browsers ignore the content. This is most useful for adding IE-specific style sheets to a web page, within which you can place overrides. For example, rather than using the box model hack shown earlier in the chapter, you would have a clean style sheet, and then override specific values in a separate style sheet for Internet Explorer 5.x, attached within a conditional comment. Generally, problems with Internet Explorer fall into the following camps: rare issues with Internet Explorer 7, problems that affect versions 6 and below, and problems that specifically affect version 5.x. With that in mind, I mostly add three IE-specific style sheets to my web pages, with the newest release at the top. Conditional comments are generally added after the ???default,??? or clean, style sheets (which in this case are the main style sheet added using a style element, and a print style sheet added using a link element).
