Template Tag body_class

The coming WordPress 2.8 provides a new Template Tag, body_class. This function gives the body element different classes, which gives you the possibility to use it effectively with CSS.

Like in the comment area and post classes, the WordPress-Developer get the best out of the database. Here an example if you open a page template “tutorial.php”:

All in all, there are following classes available:

  • rtl
  • home
  • blog
  • archive
  • date
  • search
  • paged
  • attachment
  • error404
  • single postid-(id)
  • attachmentid-(id)
  • attachment-(mime-type)
  • author
  • author-(user_nicename)
  • category
  • category-(slug)
  • tag
  • tag-(slug)
  • page-parent
  • page-child parent-pageid-(id)
  • page-template page-template-(template file name)
  • search-results
  • search-no-results
  • logged-in
  • paged-(page number)
  • single-paged-(page number)
  • page-paged-(page number)
  • category-paged-(page number)
  • tag-paged-(page number)
  • date-paged-(page number)
  • author-paged-(page number)
  • search-paged-(page number)

Template Tag automatic_feed_links

This function is in the function.php of the Default-Theme. automatic_feed_links() enables the automatic output of feed links in the header area of the document. This function is active by default, but you can turn it off, it won’t output any feed links anymore:

automatic_feed_links(false);//no output
automatic_feed_links();//no output

In single view there is the output of feed, comment feed and additionally the post-comment-feed.

    The upcoming new version of Thematic Framework For WordPress will provide classes based on the browser, the version of the browser and the os where the page is running.
    I think this is really helpful for styling..

    Drupal has been using this feature for a long time..I am going take a guess here that wordpress got the idea from Drupal.

    Hi there… I really enjoyed the post and have had fun using the body_class() function–successfully–for the ‘home’, ‘single’ and ‘page’ classes. However, I’m trying to figure out how to use the function with “specific WP pages” and for some reason I can’t figure it out. In other words, how can I set up a body class that applies only to particular WP page (e.g. page ID 19)? Any help you can offer would be much appreciated. Thanks.

    Best, Chris

    Chris, for a page i have the following output from body_class():

    page page-id-18 page-parent page-template page-template-default logged-in

    So you can use .page-id-18 in your stylesheet.

    This is very useful, makes our blog integrations so much easier. Is there any way to remove any of those ‘reserved’ class names though?

    Thanks!
