Document what diagrams fontSize works with

[PaulRBerg]

I have spent a few hours trying to understand how the fontSize config option works, only to find out that it doesn't work with flowcharts:

#2896

My documentation request is to add an explainer in your docs website to clarify what diagrams fontSize can be used with.

Hi @PaulRBerg

There are two ways of customizing themes: site-wide and to individual diagrams.

To set the font size to an individual diagram, modify the themeVariableby setting fontSize to the desired size. The default is 16px.

Here is a link to our documentation on Theme Configuration.

Here is an example from Mermaid.Live( (screenshot below) where I have set the fontSize of my flowchart to 150px.

Also, if you haven't joined already, there is a Slack workspace where you can post questions or see if someone else has posted a similar question for a quicker resolution.

Thanks for your answer, @huynhicode.

It's still unclear from this if it is possible to customize the font size of all flow charts. From issue #2896, I would be inclined to believe that the answer is "no," but I am not sure.

Thanks, but I would prefer to keep chatting here so I don't have to sign up on another Slack workspace.
