CSS to hide blog post metadata i n 7.1

I'm building a website for a book author. He has a blog, but I am also using a blog format to display his books.

He wants metadata for the blog (date published and author), but not for his books.

How can I hide metadata for one blog while keeping it displayed on another?

Thank you!

If you use Business Plan or higher, you can add this code to Book Blog Page

<style>
  .blog-meta-section {
    display: none;
}
  div.blog-item-author-date-wrapper {
    display: none !important;
}
</style>

If you use Personal/Basic Plan, please share link to Book blog page, we can give new code

Once again you save the day.

Thank you!
