Categories & Post

[theron]

Hello.

I'd like to ask about two things.

1. I don't want categories at all. Is there any way to disable them?
2. "Written by..." under the post(article) title. I want to change it to show on the right side of the post name, without "Print" and so that would look like this: "Written by Author on 15th Dec 2016" for example. No " | ", no Print button. I don't want "Written by Author in SampleCategory".

And besides I'd like to remove the social icons, "search this site" box.

Can I just edit the css? Thanks in advance.
