Can I set the default font for the HTMLViewer to be e.g. Sans Serif?
You could check WebPreferencesMBS class.
There you can define the default fonts for Mac.
This is usually done by the page you view.
Displaying pure HTML here… no sites. I can remember you could set the default font in prefs. In Safari 10.1 though this has disappeared.
If it is your own HTML, you can set the font-family and font-size for Body.
<body style="font-family: Helvetica; font-size: 14pt;">https://www.w3schools.com/cssref/pr_font_font-family.asp

OK, didn’t think of that. Makes sense. Thanks.
