Este plugin no ha sido probado con ninguna las 3 últimas versiones principales de WordPress. Puede que ya no se mantenga o no tenga soporte, y puede que tenga problemas de compatibilidad cuando se utiliza con versiones más recientes de WordPress.

Ambrosite Body Class Enhanced


When activated, this plugin causes the body_class template tag to output five additional classes.

On single posts (is_single) :
postname-[permalink slug]
single-[category slug]
parent-[parent category slug] (all parent and grandparent categories in a hierarchy of any depth)

On pages (is_page) :
pagename-[permalink slug]

On category archives (is_archive and is_category) :
parent-category-[parent category slug] (all parent and grandparent categories in a hierarchy of any depth)

Custom Taxonomies

As of version 1.3, the plugin now supports custom hierarchical taxonomies. The new body classes take the following form:

On single posts (is_single) :
single-[taxonomy]-[term slug]
parent-[taxonomy]-[parent term slug] (all parent and grandparent terms in a hierarchy of any depth)

On taxonomy archives (is_archive and is_tax) :
parent-term-[parent term slug] (all parent and grandparent terms in a hierarchy of any depth)

For single posts, the taxonomy name is included in the class name, because I felt it was important to be able to distinguish between taxonomies in cases where a post is assigned to more than one custom taxonomy, and when the same term might appear in two or more taxonomies. For example, suppose you had a real estate site with property listings in New York City, and you had two custom taxonomies defined: City and State. Then the classes would look like this:

single-city-new-york single-state-new-york

Multisite Support

As of version 1.3, the plugin now supports multisite installations. If a multisite install is detected, the plugin will output the follow additional body class on every page of the site:

site-[site ID]


If you have a post titled “Top 10 Decorating Ideas”, in category “Christmas”, with a parent category of “Holidays” and a grandparent category of “Calendar”, the additional body classes will be as follows:

postname-top-10-decorating-ideas single-christmas parent-holidays parent-calendar

Why is this useful? Because it enables you to style individual posts and pages, as well as entire categories of posts, using only CSS, without having to edit the template files or create new templates.

Continuing the above example, if I wanted to give all of the posts in the Christmas category a green heading (to give them some extra holiday cheer), I could use a CSS selector like this:

body.single-christmas h1 {
    color: green;

Going further, suppose I want to attach a background image of a Christmas tree ONLY to the “Top 10 Decorating Ideas” post:

body.postname-top-10-decorating-ideas {
    background: url('images/xmas_tree.gif') no-repeat left top;

What if I want all posts categorized under Holidays (Christmas, Thanksgiving, Easter, whatever) to have a sidebar with a gold border?

body.parent-holidays div#sidebar,  /* all posts assigned to a subcategory of Holidays */
body.single-holidays div#sidebar { /* any posts assigned directly to the Holidays category */
    border: solid 2px gold;

These are just a few examples. If you are experienced in writing CSS selectors, you will find many more uses for the new body classes. For further discussion, check this support forum thread:


  • Upload ‘ambrosite-body-class.php’ to the ‘/wp-content/plugins/’ directory.
  • Activate the plugin through the ‘Plugins’ menu in WordPress.
  • Verify your theme has the body_class function on the body element in header.php, as explained in the WordPress Codex:


The body_class template tag is already outputting the post and page IDs. Aren’t the slugs redundant?

Yes, the post IDs can be used in CSS selectors. However, the slugs are much easier to remember and use. They will also make the CSS file a lot more readable when you come back to it a month or a year later.

The post_class template tag is already outputting the category slug. Isn’t it redundant to put it on the body as well?

Putting the category slug on the body makes it possible to target elements outside of the post div. For example, if you wanted to style the sidebar on a per-category basis (e.g. change it’s width for all posts in a certain category, or even hide it completely), you could do it using the body class, but not the post class.

Still works fine. Please release an updated version so it's not flagged as obsolete.
