A ruler bar is a tool used in graphic design and desktop publishing software to measure and align objects on a page. It typically appears as a horizontal or vertical strip with markings for units of measurement. Users can drag it from the edge of the software window to measure distances accurately.
The edge of the Word window typically features a variety of elements, including the title bar, which displays the document's name and the program name, and the ribbon, which contains tabs and tools for formatting and editing text. Additionally, the status bar at the bottom provides information about the document, such as page number and word count. Various buttons for minimizing, maximizing, and closing the window are also present on the top right corner.
