Why only one font in Confluence?

Wojciech Andryszek_Deviniti

I'm new to the topic. I wonder why users can use only one font in Confluence and other solutions (like Notion). Is there a specific logic behind it, goals, or some overall reason I'm unaware of? I'm just trying to understand.

I appreciate any knowledge you can provide.

It's ease of use, and consistency.

Confluence is a wiki, meaning a place to write stuff to publish to a wide audience for them to read. 

The emphasis on read is important.  If you want people to be comfortable reading a page, do not change fonts at all (you can get away with font changes between obvious titles and sections, but even that is jarring and should be avoided)

People writing pages who think they want to use different fonts are not understanding their audience.  A consistent font makes it easier for dyslexics, people with vision problems, and speed-readers to read the page.

An ideal web page uses a single, sans-serif font, using only underlining or bold for emphasis (italics are bad for many people with dyslexia, and they interrupt speed-readers, who work from the shape of a word rather than actually reading it)

Also, most people who want to change a font, often want to change it to a bad one.  Confluence runs with a font that is not bad for anyone, so you can't make that mistake.
