What is a Page?
Posts are time-oriented objects. You write them at a specific time, and that time defines their context.
Pages, on the other hand, are most often used to present information about yourself or your site that is somehow timeless - information that is always applicable. For example, you might write a Post describing what you did or thought on a particular morning ("Breakfast was good"), but on a Page you might write something whose context is less time dependent ("This site is about breakfast").
Of course, this is your WordPress; you can do whatever you want with it and its features. Pages can be used to present any information you want to live "outside" your blog. Experiment and be creative. And, as always, have fun doing it!
Some examples of Pages to create on your site may include, Copyright, Legal Information, Reprint Permissions, Contact Information, About Me, About Site, Accessibility Statement, among other things.
In general, Pages are very similar to Posts in that they both have Titles and Content and can use your site's Presentation Templates to maintain a consistent look throughout your site. Pages, though, have several key distinctions which makes them quite different from Posts.
Writing a Page
The process of writing a page is almost exactly like writing a Post.
- Login to the Administration Panel. You'll see your Dashboard.
- Click the dark blue tab for Write. You'll see the Write Post page. Select the white Write Page tab.
- Start filling in the blanks. The most important are Page Title and Page Content. You can drag the lower right corner of the post box to make it larger.
- You can change the order in which Pages are displayed in your index by using the Page Order box on the right-hand side.
- You can use the Page Parent box to create a hierarchy of related pages; for instance, you could put detail about projects you mention in your CV Page into Sub-Pages of that CV page.
- When you are ready, click Publish. You can also Save a work in progress, then come back later and Publish when you're ready to let others see your work.
