Color and Width Changes to CSS

A few things for CSS on my desktop version.

1 – I’m curious what to change in CSS for my blog titles to be black (they’re white at the moment).

2 – On my desktop version of my footer, the areas of [shop, product category, new on the blog, join our community] are not evenly spaced apart. New on the blog and join our community are very close together. What should I enter to change this?

3 – On my desktop version of my menu, how can I slightly bring these tabs a little closer together in CSS?

Thanks
