Hi @NitaHarun, 

You can easily add a grid to a web map in Map Viewer in the Editor Settings. This grid consists of horizontal and vertical lines that can be used as a reference guide to snap to while drawing or placing features on the map. 

However, if you require a grid in a specific coordinate system or projection, then this support article can walk you through some other options: https://support.esri.com/en-us/knowledge-base/how-to-add-a-grid-layer-in-arcgis-online-000024951
