Styling is the process of binding visual metadata to a document. Questions relating to css should use the css tag instead of this tag. Likewise, more specific style language/technique tags should be used instead of this general tag.

Styling rules can be defined within a document or via an external stylesheet.

An assortment of programming languages may be used to apply styles to digital products.

Most commonly, Joomla! websites are styled largely by Cascading Style Sheets (CSS) and inline style declarations.
