Block dashboard 1 zoom in and zoom out options

Hello house!
À quick one. I’ll love to fixed the zoom-in and zoom-out of my dashboard 1 to a particular width and height. I’m sure this can be achieved using the template node and some css code but I can’t figure it out. Please any help will be appreciated

What exactly do you mean by zoom in/out?

Thank you Colin.
On dashboard you can zoom in or out using Ctrl -+ or Ctrl - to have a better view of your data. I want my dashboard to occupy the whole pc screen - which has been done already, and block users from zooming in or out of the dashboard.

That is a browser function, not the dashboard. It works on any web page. I don't know whether it is possible for a site to disable it.
