//! Character Styles and Paragraph Styles panels.
|
|
//!
|
|
//! A style is a named, partial set of attributes ([`TextStyleDef`]); text using it records the
|
|
//! name in `CharStyle::style_name` / `ParaStyle::style_name`. Applying a style sets its attributes
|
|
//! (Clear Overrides first resets to the Normal style). Redefining a style updates its users but keeps
|
|
//! their local overrides: an attribute changes only where it still had the old style's value.
