how to delete author and internal navigation in post

Hi there,

Welcome to GP :)

You can hide author in Blog > Blog Content: https://docs.generatepress.com/article/blog-overview/#blog-content

Option to hide post navigation is coming very soon. For now use this CSS:

.post-navigation {
    display: none;
}

Adding CSS: https://docs.generatepress.com/article/adding-css/

Let me know.

Is there a way to hide the author on individual blog posts? I have a news blog, and some of the articles are written and submitted by authors who aren't Editors on the blog. I want to be able to post their content and give them credit without giving them access to the site. I can give them a byline within the body copy, but then I want to be able to hide the author on just those posts. Is there a way to do that? Or is there a different solution for my situation?

If you use Tom's Simple CSS plugin: https://docs.generatepress.com/article/adding-css/#additional-css
It gives a CSS metabox for each page/post.

Then on the post you want to hide the author, add this CSS in:

.site-main .author {
    display: none;
}

Let me know if this is what you wanted.

Would I be able to use this code in the Code Snippets plugin? I prefer to install as few plugins as possible, and I'm already using Code Snippets for adding Google fonts.

No code snippet is for PHP.

The code I provided is CSS.
