How to realize the mouse wheel zoom in and out of the page in WinForm

There's a discussion about this at https://magpcss.org/ceforum/viewtopic.php?f=6&t=16480

Hooking the event in JavaScript is probably easier, might look something like the following

        // Ctrl+Mousewheel handler for zoom in and out...
window.onwheel=function(event)
{
          if (event.ctrlKey){
           if (event.wheelDelta < 0){
        
              // Use CefSharp.PostMessage to notify zoom out;
            }
            else if (event.wheelDelta > 0){
        
              // Use CefSharp.PostMessage to notify zoom in
            }
          }
 };
