System Fonts enqueues a stylesheet that lets you use the native font on each operating system and defines a system-ui css @font-face that you can use on the customizer, your theme’s settings or your own code.
The Twenty Seventeen theme uses this css selector for the body text:
body, button, input, select, textarea { font-family: "Libre Franklin", "Helvetica Neue", helvetica, arial, sans-serif; }
We are going to replace it with the default system font.
In you WordPress site, go to Appearance > Customize > Additional CSS
and paste this code
body, button, input, select, textarea { font-family: system-ui; }
Appart from them font-family, there are other font-properties available:
For example this is the code make an element’s text semibold and cursive:
#my-element { font-family: system-ui; font-weight: 500; font-style: italic; }
/wp-content/plugins/system-fonts
directory, or install the plugin through the WordPress plugins screen.
