Overview - ISO/IEC 18036:2003 (Web browser toolbar icons)
ISO/IEC 18036:2003 defines a consistent set of icon symbols and functions for World Wide Web browser toolbars. It specifies the primary purpose, typical visual components, and allowable variations for common toolbar icons so that users can reliably identify and invoke browser actions. The standard covers icons such as Back, Forward, Reload/Refresh, Home, Search, Print, Stop, Bookmarks/Favourites, and Save (Page) and describes how these icons should behave and appear on screen.
Key topics and requirements
- Primary functions and specific instances: Each icon is defined by its main function (e.g., Back returns to the previously viewed page) and a recommended graphic representation (e.g., left-pointing triangle for Back).
- Icon components and graphics: Detailed component descriptions for each symbol (triangles and shafts for Back/Forward, cyclic arrow for Refresh, house for Home, torch for Search, printer for Print, white “X” in a dark/red circle for Stop, folder with “+” for Bookmarks, and open folder with arrow for Save).
- Interaction and selection: Icons must be selectable by common pointing devices (e.g., mouse click) and act upon pre-selected or default objects.
- Arrangement and grouping: Related toolbar icons should be grouped and visually organized (rows, columns, or boxes) for ease of use.
- Visual feedback and status: There must be clear visual discriminability between available and unavailable functions, consistent feedback when functions are invoked, and status indication for ongoing actions.
- Recommendations: Guidance on color use, visual prominence, avoiding text inside icons unless necessary, and permitting user customization of icon arrangement.
Practical applications and users
- Browser vendors and UI designers: Use the standard to ensure consistent, recognizable toolbar controls across platforms and to improve usability and accessibility.
- Software developers and product managers: Apply the icon definitions and interaction requirements when implementing browser features, extensions, or embedded web viewers.
- UX researchers and accessibility specialists: Reference the visual feedback, grouping and text/typeface recommendations to design inclusive toolbars.
- Corporate IT and product teams: Adopt the standard when creating custom browsers or web-based applications that expose toolbar controls.
Benefits include improved user recognition, reduced learning curve for browser controls, and consistent behavior across implementations.
