Hi,
I want to disable the featured images from appearing at the top of the posts. How should I do that?
Also, how to reduce the font size of the title? Do I need to enable the typography element to do that? If so will it add more requests/size to my page?
2. Yes you need to enable the Typography module then you can adjust the sizes in Customizer > Typography. Enabling this module and changing the font size will not increase requests / page size.
NOTE: If you add more fonts eg. have a different font family for other headings – this will increase the number of requests.
