VIM: different font size in each split

Question

Is it possible to set different font sizes in different split views in vim? I often do :vsplit to open documentation in one and source in another view, and would like to use

Answer 1

Type :help 'guifont':

'guifont' 'gfn'     string  (default "")
            global
            {not in Vi}
            {only available when compiled with GUI enabled}

We can see that: guifont is a global option. So when you change it, it affect all windows.

In the future, this option can be global or local to buffer/window(such as cm).
