Possible to apply zoom-buttons zoom to mouse-scrollwheel zoom?

As can be seen on this embedded map, when user scrolls mousewheel up one notch on Windows 10), it zooms in A LOT further than when user clicks “+” zoom in button in top left corner of embedded map. Can a website-owner change the amount it zooms in/out when scrolling mousewheel? If not, can we please have mousewheel to zoom in just as little as the “+” and “-” buttons zoom in/out on Windows 10?



It’s not a windows setting is it? On Windows 10 here mouse wheel zoom in goes one zoom level at a time (on openstreetmap.org). Your site doesn’t load currently.
