My clients site is complete, but he requested that I center the heading titles:
"Gallery" "Demo Video" "Thumbtack Pro Reviews" "Contact Us"
Not possible... GoCentral's themes and layouts are what they are with no access to the background code or CSS to make any changes. That's what a web builder is. It makes it easy to have a great looking site bit but you do not have the ability to modify the core files that control many of the features and design.
If you want that level of flexibility and control take a look at WordPress... 😉
@Mellowatts You are using the "Clarity" theme... it's titles are left justified. All the other themes have centered titles. Maybe look at those themes for your website.
