I’m having a little difficulty with a CSS override on the blog page.
The idea is to have sub-headings (such as titles) on our web page in a different font and color than the body (content). We can almost get there by setting the font in Appearance > Customize > Typography > Headings; here we can change the typeface of <h2> and <h3> tags but not the color.
On a regular page the CSS override works just fine.
On the blog page, the very same code does not. Using the inspector on the browser I obtained the class and tried to override it that way but it still does not work.
I found the customizer has a setting to change color. So it appears that headings are set in one place (Appearance > Customize > Typography > Headings) and the color property of the headings is in another (Appearance > Customize > Colors > Content) where blog post titles can be changed.
Whew. I’d still like to know why the Custom CSS didn’t work, but that is just curiosity now.
