When you are using the Google map on your website it will override the the scroll mouse event and act as the zoom on the maps. This feature makes it really easy to zoom on a certain position on the map, you just hover over the location and use your mouse wheel to zoom in or out.
But this causes a problem when you have a large or full screen map, as you scroll on the page the map will zoom out, making it difficult to scroll on the page using the mouse wheel.

Step 2Check the box of ‘Turn Off Scrolling Wheel’ option in the ‘Map information’ section.
