Label definition and instructions for use

Comment tags are used to insert comments in the source document. Comments are not displayed in the browser.

You can use comments to interpret your code, which helps you edit the code at a later time. It is especially useful when there is a large amount of code.

You can also store customized information for the program in the comments content. In this case, this information is not visible to the user, but is available to the program. It is a good habit to put comments or style elements in the comment text to prevent old browsers that do not support scripts or styles from displaying them as plain text.

Comment: the last two forward slashes (/ /) on the command line are JavaScript comment symbols. This ensures that JavaScript does not execute the-- > tag.

In addition to having a very obvious role in the source document, many Web servers also use annotations to implement the unique features of the document server software. These servers can scan the document, find a specific sequence of characters in traditional HTML/XHTML comments, and then take action based on the commands embedded in the comments. These actions may simply include text from other files (so-called server-side inclusion, server-insideinclude), or complex execution of other commands to dynamically generate the contents of the document.
