1. Is it possible to edit the default font size for better legibility (on posts)?
2. If posts don’t have a featured image (quotes or links) in similar posts they showing the heading on grey. Is it possible to add there a global default image, may be via the options?
Hi malspiker,
You can try to use this custom css code. (Change the color code)
Wordpress didn’t allow the add the custom image url there but you want to add color to background so this custom css code will solve your issue.
