Hi!
I’m using blix too. As you add pages the page buttons will automatically show up in the horizontal nav bar beside Home and About.
for an example see my site:
https://careerspaceezine.com
There is really only 4-5 spaces for buttons though so if you want to create more pages you will have to create a secondary nav bar (which is detailed in the Blix readme.html file), if you haven’t located it already…..
There is a cheat sheet for Blix that comes with your theme although you have to dig for it in your theme files. It will show you how to hook up your archive and contact (with a handy contact form) that is included with your theme. It will also show you how to add an “about” shorty in your side nav bar as well as the secondary nav bar.
The version of wordpress will be in the wordpress readme.html file. It will also say in the main template.
For editing the color of the words my guess would be to try an inline class of CSS. An inline will override the set CSS font color for the website.
