Extend the 5 AsciiDoc admonitions with 324 ISO-compliant symbols.

Override an admonition with a custom class to display it in the style of the desired ISO symbol. To do this, enter the ISO code above the admonition. Precede it with the admonition type you want to override for this single instance. It doesn’t matter which of the five admonition types you use—all work. Admonitions without a custom CSS class remain in the classic style.

Example:

[WARNING.W001]

General warning
