Set default config fonts in ckeditor 5

Question

I have project with ckeditor 5. I try to set default config for family and size font's. In ckeditor 4 we could set default config fonts by

font_defaultLabel and fontSize_defaultLabel.

So how i can set this same in ckeditor 5 ?

 function SetDefaultFont(fontSize) {
        CKEDITOR.config.fontSize_defaultLabel = fontSize;
    }

function SetDefaultFontFamily(fontFamily) {
    CKEDITOR.config.font_defaultLabel = fontFamily;
}

Answer 1

I don't know if this is the answer you're looking for, but I also had a similar problem and found the following solution while searching.

By default, the default font-size is 1em. Therefore, if you adjust the font-size of the parent element, the font size inside the editor is linked and adjusted.

You can do that by setting a css variable and set the variable as your preferred one.

css class:

.ck-editor__editable_inline p
{
  font-size: var(--fontSize) !important;
  font-family: var(--fontFamily) !important;
}

and then ngOnInit (I'm using Angular version)

 ngOnInit() { 
  document.documentElement.style.setProperty('--fontSize', '15px');
  document.documentElement.style.setProperty('--fontFamily', 'Cairo');
 }
