Go to the Customizer -> Blog Settings.
It is recommended that you have a blog page open when starting to customize blog content, as the changes you make here won’t be visible otherwise.
Show Post Author Info in Sidebar
Enable this option to include a section dedicated to information about the post author, in the blog sidebar.
Show Post Title in Post Page
If you enable this option, the post title will be displayed in the post page. For not showing a title, leave the checkbox unchecked.
Highlight First Post
Enable this option to showcase the most recent post on the blog. It will help you make that post stand out, especially if you have multiple posts already published and you want to put an emphasis on the most recent one.
