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 that make them quite different from Posts.

• pages are last time dependent that post
• they can be organized into pages and subpages
• each page can have different page templates

What Pages are Not:

• Pages are not Posts. They do not cycle through your blog’s main page. (Note: You can include Posts in Pages by using the Inline Posts Plugin.)
• Pages cannot be associated with Categories and cannot be assigned Tags.
• Pages are not files. They are stored in your database just like Posts are.
• Although you can put Template Tags and PHP code into a Page Template, you cannot put these into the content of a Page and expect them to run.
