Your replie certainly hints at an answer my question. Let me see if I get it. I want to design a blog page. It may even be a blog "index" page. I have no guide to the taxonomy of blog pages. So I wonder if there might be more than one kind of blog page: the individual post, the archive of posts, and the display of posts of given category or tag. I do not know if one designed "blog" page becomes the basis for all three. Perhaps you could help me understand this.
Next I am going to guess that a blog page could be designed in Pro's Editor. Your link to wordpress.org makes it seem that this is the process. I design a content-free page which will be assigned the task of being the page for "posts." Once it is assigned that task it can no longer be edited. Is that correct?
If I want all displayed blog posts to contain a fullwidth slider as the unique and primary content of each individual post, then I need to design some kind of fullwidth page, with a content band ready to hold that slider that I will be posting as the content in an individual post. Note that this is not a single slider appearing on all post pages. Each slider is be a unique one; it is the actual content of an individual post (separate projects of the landscape architecture client). Is that possible?
My interest is to find out how to make a custom blog page within Pro. Any help you can write (or existing process text you can direct me to) would be greatly appreciated.
