+You can add classes, attributes, and other identifiers to regions of content using Divs and Spans.
+Although the terms *Div* and *Span* originate in HTML, the syntax is used in Quarto across output formats.
+For example, [Callout Blocks](#callout-blocks) are specified using the div syntax, and [Small Caps](#other-spans) are specified using the span syntax, and both work for many formats beyond HTML.
+You may also use CSS and/or a [Filter](/docs/extensions/filters.qmd) along with Divs and Spans to provide styling or other behavior within rendered documents beyond what Quarto provides.

 Fences without attributes are always closing fences. Unlike with fenced code blocks, the number of colons in the closing fence need not match the number in the opening fence. However, it can be helpful for visual clarity to use fences of different lengths to distinguish nested divs from their parents.

 ### Ordering of Attributes
 
 Both divs and spans in Pandoc can have any combination of identifiers, classes, and (potentially many) key-value attributes. In order for these to be recognized by Pandoc, they have to be provided in a specific order: identifiers, classes, and then key-value attributes. Any of these can be omitted, but must follow that order if they are provided. For example, the following is valid:
