How is the tag parameter used in WP _ query?
The tag parameter takes the tag slug for its value and can be used to find posts with one tag or with any of a string of tags.

So the above will query posts with either or both of tags 21 or 23 but not tag 22. This parameter lets you find posts with one or more of an array of tags. It works in the same way as tag when used with an array: This will query posts with any or all of the tags listed.
Can you use category name in WP _ query?
The category_name parameter uses the category slug, not the name (confusing, I know!). Again, you can use it with a single category or with a string of categories to find posts that are in any of the categories. And to find posts in one or more of a number of categories, use this:
