I increased the font size of the content. Apparently the “Posted on” and “by” right under the post title in single posts also followed.
Is there a way to reduce this down to the original size of the text without affecting the now-bigger content text?
I’ve attached a partial screen shot.
I hope you are well today and thank you for your question.
You can try achieving this by adding the following CSS code in the Custom CSS option of your theme on the below path.
Admin Area -> Appearance -> Customize -> Additional CSS
font-size: 14px !important;
