Probably better if all font sizes were in ems not px, I'm sure on @codebrainz 4k monitor 14px is small but its ok on my 2k and huge on the laptop.

(or maybe @codebrainz just needs glasses :grin: )

`em`s and `rem`s are ultimately based on the browser setting (unless somebody hard coded a `px` somewhere in the inheritance tree). The browser setting is controlled by the user to make text readable to them, webpages should not override the user by hard setting `px` when they don't know what device it is shown on.

And as usual the web is dominated by the wrong way to do things, from the Mozilla docs:

``` Note: Defining font sizes in px is not accessible, because the user cannot change the font size from the browser. For example, users with limited vision may wish to set the font size much larger than the size chosen by a web designer. Avoid using them for font sizes if you wish to create an inclusive design. ```

1em is fine (with default browser size of 16px).
