Can we use the native font instead of Arial for Stack Exchange sites?

Question

First of all, I'm a bit allergic to default fonts like Arial, Times New Roman etc.

You already are aware that, all the Stack Exchange sites (except a few) recently switched to the default fonts:

font-family: Arial,"Helvetica Neue",Helvetica,sans-serif;

That's not bad and works everywhere - that's the real cause - I appreciate that.

But the good thing is: recently Github and WordPress switched to the Native Font Family that's nicer to me.

+-----------+-----------------------------------------------------------------------------------------------------------------------------------------------------+
| Github    | font-family: -apple-system, BlinkMacSystemFont, "Segoe UI", Helvetica, Arial, sans-serif, "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol";
+-----------+-----------------------------------------------------------------------------------------------------------------------------------------------------+
| WordPress | font-family: -apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, Oxygen-Sans, Ubuntu, Cantarell, "Helvetica Neue", sans-serif;
+-----------+-----------------------------------------------------------------------------------------------------------------------------------------------------+

I think it's a community decision that's not that bad to follow.

It may look like I'm proposing something that interests me only — but actually I'm asking for something nicer, soothing and not buggy. I hope I'm clear with my POV.

Can we go with such a native font family?

Answer 1

You can do this yourself, just add a custom stylesheet (how this works varies per browser) with the following rule:

body {
    font-family: -apple-system, BlinkMacSystemFont, "Segoe UI", Helvetica, Arial, sans-serif, "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol" !important;
}
