Classactive

Classactive is a CSS class name used in HTML documents to denote that an element is currently active or selected within a related set. It is not a standardized keyword in HTML or CSS; its meaning and styling are defined by the project’s CSS rules and scripting.

Typical usage involves marking the active item in navigation menus, tabs, accordions, sliders, or item collections. When an element has the class classactive, CSS selectors such as .classactive enable distinct styling—commonly changes to color, background, font weight, or borders—to visually indicate the active state. The class is usually toggled by JavaScript in response to user actions or by server-side rendering, rather than by a built-in browser state.

Classactive is distinct from the :active pseudo-class, which reflects a momentary state while an element is being activated by user input. A class such as classactive persists across events and can be updated to reflect changes in selection or focus.

Accessibility considerations include using the class as a presentational cue in combination with accessible semantics. For example, an active link may also use aria-current="page" or a similar ARIA attribute to convey the current state to assistive technologies, in addition to styling via the class.

Implementation tips include using element.classList.add('classactive') and element.classList.remove('classactive') to toggle the state, and adopting descriptive names such as is-active or active-item when appropriate. Care should be taken to ensure consistent naming and to provide accessible cues beyond visual styling.
