Represents a conditional comment.
Conditional comments are used to control the display of elements in order to create a more consistent viewing experience. In order to make a number of features visible in a Web browser, you can specify HTML elements that are used only by Web browsers to display content. Conditional comments are specified around these elements.
A conditional comment can have one of two forms. The down-level-revealed form reveals the contents of the comment in Web browsers. The down-level-hidden form hides the contents of the comment.
Down-level revealed comment
Down-level hidden comment
In the following example, the content is displayed if the browser is a version of Internet Explorer 5 or later.
