Decrease Font of "Published on" below post title

Hi there,

1. go to Customizer > Typography and Add New Typography
2. in the Target Element list, select Custom
3. in the CSS Class field provided add: .single-post .entry-header .entry-meta
4. Set your font styles.

Thanks! All is good!

I'm guessing that you are still on the old typography system:

Found it, it was there! :)

Glad to hear :)
